Possible options for solving the error “DNS server is not responding. What to do if the DNS server does not respond: step-by-step instructions

DNS (Domain Name System) is an add-on over the TCP/IP Internet protocol that allows you to use familiar site names like www.yandex.ru instead of incomprehensible addresses like 147.15.28.677. This mechanism is implemented both on the provider side (using DNS servers) and on client equipment using special services and operating system services. Also additional support DNS can be provided by the client's communication equipment: router, access point or 3G modem. For the average user, a Domain Name System (DNS) problem is like an Internet connection going down because they can't access web pages. Therefore, it is very important to understand what problems may arise in the operation of DNS services and how to quickly resolve them.

Causes of DNS Service Errors

An important element of the Internet infrastructure are domain name servers (DNS). They are the ones who convert the symbolic name of the site into the IP address through which access occurs. As a rule, such servers are part of the hardware and software package of your Internet provider, but there are also alternative sites that can be accessed through the appropriate settings of the network adapter or home router. Since the DNS server is regular computer(or a cluster of computers), it may freeze, become infected with a computer virus, or be attacked by a spam network. Eventually, a power failure may occur at the site and the DNS server will stop working. The result will be the impossibility of normal Internet surfing, since the symbolic names of your sites will not be converted to IP addresses and you will see a message like the following in the Internet browser window:

A message like this indicates a problem with the DNS system.

Checking and changing the DNS server settings in the connection properties, registering an alternative DNS address

The first thing to do when faced with a DNS addressing error is to check DNS settings both in the network connection properties and in the control panel of your home router. If your ISP's DNS server is down, you can connect to one of alternative DNS servers and restore the functionality of the Internet channel. This is not difficult to do.

On operating systems Windows 7, 8, 10

In OS Windows family DNS settings located in the TCP/IP protocol settings of the network adapter. To check and change them, you need to perform the following manipulations:

1. Using a window command line Open the Network Connections snap-in.

   Open the Network Connections snap-in using the Windows command line

2. In the Network Connections window, select network adapter, through which access to the Internet is organized and open its properties.

   Select the network connection through which Internet access is organized and open its properties

3. From the list of network adapter properties and services, open the TCP/IP v4 protocol settings.

   The TCP/IP protocol is the basis for connecting to the Internet and DNS parameters are in its settings

4. DNS settings - two fields at the bottom of the window, for the main and alternative server. If these fields are empty, the operating system will use the DNS server address provided by the provider or registered in the control panel of the home router.

   By default, DNS addresses are obtained automatically; to enter addresses manually, turn on the “use the following DNS server addresses” mode

5. To use an alternative DNS server, enter its primary and alternate addresses in the appropriate fields of the dialog box. In this case, the popular Google DNS server is used.

   There are both pros and cons to using alternative DNS servers. A huge advantage is the ability to bypass blocking of some sites that were introduced by the provider or system administrator of the enterprise

6. Click the "OK" button for the changes to take effect.

In the settings of the router (router)

The control panels (web interfaces) of routers look different for different routers, but they are all intuitive and designed for an untrained user. Having learned how to change the DNS server settings on one model of router, it will be easy to do this on others.

In order to access the router's web interface, you need to find out network address. This can be done using the ipconfig command, calling it from the command line. The “default gateway” item displays the router’s network address. To access the router's web interface, you need to enter this address in your Internet browser.

Using the ipconfig command, you can find out the router's address and access its web panel

Having opened the web interface, we will enter the DNS server addresses into the settings. Let's do this using the example of the settings of a router from the popular TP-Link family.

1. After entering the router address, we get to the main page of its web panel. This is usually the status page.

   On home page the router's web panel displays all basic settings

2. Go to the “Network” section, to the “WAN” tab. Here you can find the settings for connecting to your Internet provider. If the connection type is “dynamic IP” (Dynamic IP) or “static IP” (Static IP), then you can specify the addresses of the DNS servers directly on this tab, in the appropriate fields.

   DNS server addresses can be specified in the WAN settings if the connection type is without authorization (just an IP address)

3. If the connection type to the provider is “PPPoE”, “PPTP” or “L2TP”, server settings DNS is better make in the DHCP section.

   In the DHCP settings you can also specify alternative DNS server addresses

Scan your system for viruses

The category has existed for quite some time computer viruses, specializing in the theft of users’ personal data. One of the tactics used by such “Trojan horses” is to connect a fictitious domain name server to the operating system. This allows attackers to redirect the user instead of the site mail program, payment system or electronic wallet to specially created fake copies, which are used to steal passwords, electronic keys, and even two-factor authentication parameters.

If your frequently visited pages do not open the first time, with a long delay or do not open at all, and the banking program website begins to look a little different, there is a reason to stop authorization attempts, disconnect your computer from the Internet and full check systems using antivirus program. Although there are a large number of shareware and freeware antivirus packages, count on real protection is only possible using a commercial “first echelon” antivirus package: Kaspersky, Dr. Web or ESET NOD32.

In addition to the high efficiency of scanning and cleaning your computer from virus debris, these packages contain resident modules for monitoring Internet activity and will be able to nip attempts in the bud virus programs take control of your system.

The NOD32 antivirus package will provide protection against a wide range of viruses in real time

Setting up antivirus and firewall

With rare exceptions, the settings of the antivirus package and firewall (firewall) should not lead to disruption of DNS services. The only reason for this can be changing the settings of the “expert” mode inexperienced user. Try disabling the firewall for a short period of time and antivirus protection. If this fixes the problem, reset the antivirus package or firewall settings to the preset “default” settings.

Recovery initial settings built-in Windows Firewall will help eliminate problems with opening some sites

Updating network card drivers

Installing more up-to-date new network adapter drivers will help your Internet connection work more efficiently, ensuring quick access to DNS servers and eliminate errors that occur when opening web pages.

1. Using a keyboard shortcut bring up the system information window, and from there open the “Device Manager” link.

   Open Device Manager from the System Information window

2. Expand the “Network adapters” section, select the one you need from the list and right-click on it to open the context menu.

   Expand the list of network adapters and select the one whose drivers need to be updated

3. In the opened context menu select “Update drivers...” and wait for the update to complete.

   Run the procedure automatic update drivers

Automatic updating of network card drivers will only be possible when the Internet connection is working.

Rebooting the computer and router

To “bring to life” the equipment - the network adapter of a computer or laptop, a router, an access point, sometimes it is enough to reboot these devices.

The computer is restarted using standard operating system tools Windows systems. Just select the shutdown icon from the Start menu and select “restart” from the drop-down list.

Restart your computer using the operating system's Start menu

The router can also be restarted using the corresponding section of the web interface, but a more reliable method would be a power reboot: turn off the device using the switch on the rear panel or by unplugging its AC adapter from the socket. Wait 15-20 seconds and then turn the power back on.

If there is no power switch on the back of the router, turn it off by unplugging the AC adapter from the outlet.

Restarting and diagnosing the Windows DNS Client service

Like many other system services, the DNS Client is turned on, turned off and restarted through the standard Administrative Tools applet in the Windows Control Panel:

Clear DNS cache and other network settings via the command line

During active Internet surfing, a significant amount of data about the addresses of visited resources accumulates in the DNS cache. Using a DNS cache by your browser instead of calling a DNS server should improve page opening speed, but in practice the data in the cache may become out of date and the page may no longer be able to be opened. In this case, the DNS cache needs to be cleared, which is easy to do using Windows command line tools.

1. While holding down the Windows key, press the X key.
2. Select "Command Prompt (Admin)".
3. At the command prompt, type “ipconfig /flushdns” and press enter.
4. Type ipconfig /registerdns and press Enter.
5. Type ipconfig /release and press Enter.
6. Type ipconfig /renew and press Enter.
7. Enter netsh winsock reset and press Enter.
8. Restart your computer.

Nothing helps: what to do

If all your attempts to “reach” the necessary sites have not been successful, the problem is on the side of the Internet provider. In this case, we can only rely on the efficiency of the service technical support and the qualifications of service engineers who will troubleshoot problems as quickly as possible. By and large, a call to hotline Internet provider should be the first thing the user does when web pages stop opening for him.

If having an Internet channel 24 a day, seven days a week is vital for you, it’s a good idea to take care of a backup channel that will cover your needs while the main one is undergoing maintenance. It can be implemented using the link wireless router with a USB port where you need to connect a cellular 3G modem. The router settings allow you to connect 3G Internet only when the main channel is unavailable.

A router with a USB port will allow you to organize a backup Internet channel using a 3G cellular modem

The Domain Name System (DNS) is one of the most important, as it provides the level of transparency and comfort without which the Internet would remain closed network for IT specialists and geeks. Fortunately, each type of DNS problem is fairly easy to diagnose and fix, both on the client side and on the provider side. Follow the instructions exactly and your browser will never display the same annoying error window.

This article will discuss the situation when, when connecting to the Internet, the system reports that the DNS server is not responding. Fixing this problem is quite simple; all you need to do is follow the recommendations from the article.

To fix the problem you will need to follow these instructions:

1. Open Start and go to Control Panel.

2. In the new window, go to the "Administration" section, and then open the "Services" link.

3. Find “DNS Client” in the list of services and check if this service is running. If not, right-click on it, and then go to “Properties”.

4. In the window that appears, in the “Startup type” column, select the “Automatic” option. Save your changes before exiting.

If everything is fine with this service, then you additionally need to perform some more actions:

1) Open Start and go to Control Panel. Open the "Network and Sharing Center" section shared access».

2) In the new window, pay attention to the right side and open the “Change adapter settings” menu.

3) Right-click on your Internet connection and select “Properties”.

4) In the list of components we need “IP version 4 (TCP/IPv4)”. Select it with one click, and then click the activated “Properties” button.

5) More than likely, in the window that opens you will have the option “Obtain DNS server address automatically” checked. It needs to be changed to “Use the following DNS server addresses.”

6) In the “Preferred DNS Server” column, enter 8. 8. 8. 8, and in the “Alternative DMS Server” column, enter 8. 8. 4. 4. These parameters are the public addresses of Google servers.

If these actions do not bring results, then there may be a problem with the operating system itself. You can perform a system rollback to the restore point when the problem did not yet make itself felt. To do this, open “Start” and use the search to find the “System Restore” menu. Open it and roll back the OS. Please note that after performing the restore, the computer will need to be rebooted.

What to do if the DNS server does not respond?

When the DNS server does not respond, it’s a shame not to know what to do. After all, all the equipment is in good working order, there are funds on the balance sheet. But there is no Internet itself due to a banal error in the settings. At the same time, you cannot complain about a breakdown of your laptop or computer, the modem is in perfect order and the provider itself has no problems. But don’t worry, the settings change within a minute and are updated almost instantly. This will be discussed below.

Why are DNS servers needed?

Before moving on to the problem, you need to understand what DNS servers are. By accessing any page located on the network, you gain access to a specific section of the remote server. This directory stores files that the browser interprets and provides information to you in the form of an information page. Each server has its own IP address, which is used to gain access. This practice was convenient when the Internet was a network of several dozen servers. The set of numbers was ideal for scientists accustomed to strict consistency and hierarchy of data. But as soon as the Internet went beyond the laboratory and became an entertainment public network, there was a need for some other way to identify sites. In order to meet the growing demands of the audience, domains consisting of Latin characters were introduced. Several years ago, their Cyrillic counterparts appeared for visitors from the CIS.

Watch a video about how DNS servers work:

DNS servers exist to correctly redirect from IP to domains.

What problems might arise?

Who most often has problems with servers? Most susceptible to it are owners of modems who do not want or cannot switch to the connection option using a network cable. In the last few years, such a failure has become very common among providers from Belarus. If you are not using a wireless connection, this problem can only occur if you yourself changed something in the Internet settings. Or as a consequence of a virus or other malicious software affecting the system. Then first of all check the activity of your firewall and the activity of your antivirus. Both programs have been disabled long time without your knowledge? Reason to worry about your network security. Often the problem occurs with a factory modem that the user decided to configure himself. Missing several points in the instructions or inconsistently performing moves leads to the appearance of such an unpleasant notification.

DNS server is not responding, how to fix it?

What can we do without having access to the network:

1. Reboot the modem. The simplest and effective way, just reboot the device. Helps with eliminating most minor troubles if a problem arose during use. After a reboot, the equipment returns to the original parameters that were at the time of startup.
2. Check if the DNS address is specified correctly in the settings. To do this we need “Internet Protocol v4”, which can be found in the properties of “connections via local network». Required address You can find out from your provider; it must be indicated in the documents issued to you.
3. Update the drivers for the network card. This manipulation helps solve the problem if previous driver did not work correctly.
4. Check your antivirus and firewall settings again. Some systems block access to the network through wireless networks or specific IPs. Go to settings and make sure everything is in order.

Device or resource DNS server is not responding

All these methods are designed to assume that the provider does not have any problems, and the problem lies in your lost settings or a faulty network card. But sometimes things may be different. Due to congestion or purely technical problems, the operator does not have enough capacity, and some of its DNS servers are not working. No amount of “dancing with a tambourine” will help you in such a situation, because the problem was not created by you.

In this case, there are two generally accepted solutions. If you do not have an urgent need to gain access in the next few minutes, simply notify the operator about the current situation and demand as much as possible prompt solution. But you understand perfectly well that any malfunction requires a certain time to eliminate it. The servers will start working in a few hours, your time will be wasted. If deadlines are running out, important work has not been completed, or you urgently need to contact someone, the proposed option is not suitable. If you have a DNS client service running, you can use Google's DNS. Most often, the user makes a mistake by changing the server settings to connect using a network cable, leaving the data for the same wireless connections. If you are afraid of confusion, change the parameters in both fields; this will not reduce the performance of your laptop or computer.

What if it's not a fault?

Public access points and workplaces often block access to certain resources. The list of “undesirable” sites includes:

1. Social media.
2. Online cinemas.
3. Torrents.
4. Resources with prohibited content.

In this case, you can also correct the situation in two ways. Either talk to the network administrator and ask to remove the restriction, or use anonymity tools. Most of the restrictions help you bypass proxy servers. Dozens of websites and browser extensions are now available, thanks to which even a beginner can understand the issue. More advanced users can use the TOR or i2p browser. These last two options are not suitable for visiting social networks.

When the DNS server does not respond, not all experienced network users know what to do. It is enough to call the provider at the main office and ask him to quickly resolve the problem. Even if she is on your side, the employees will explain what needs to be done and in what order.

What to do if the DNS server is unavailable

The problem when the DNS server does not respond persistently haunts users of the Russian segment global network. Although you can easily get rid of most of the difficulties that arise simply by reconfiguring the DNS for the proper functioning of the Internet on the user’s computer.

If the DNS server is unavailable, and all the user’s devices are in good condition and there are no financial debts to the provider, then, as a rule, there is no access to world wide web due to incorrect settings. You just need to know how to correct errors in the settings and there will be no difficulties with Internet access.

Below is a detailed guide to fixing the problem; you just need to strictly follow all the sequential steps of the instructions.

What are DNS servers used for?

What is it and why are DNS servers needed? When going to any website on the Internet, a certain directory on the server becomes available to the user. This section stores information that the user's computer's Internet browser reproduces in the form of a familiar web page. All servers have an individual “IP”, through which login is carried out.

The main requirement for DNS is that they provide accurate redirection from the “IP address” to domains that no longer have a digital address, but an alphabetic one. For example, the Internet resource “nastrojkin.ru” has a domain name of “nastrojkin” and a zone of “.ru”. On the World Wide Web, this site has an IP - 46.36.219.125. The DNS service, if necessary, gives the user access to nastrojkin.ru with the digital address 46.36.219.125, because machines can only understand numeric codes, not alphabetic ones. However, sometimes it happens that the servers do not work correctly and then an unpleasant message is displayed on the user’s monitor: “The DNS server is not responding.”

A yellow triangle with “!” appears on the Set panel. inside.

Instructions for troubleshooting

The following sequential steps must be performed:

When the above service is running, but there is still no Internet access, you need to take the following steps:

If there is no access to the Internet after carefully following the above steps, most likely there are errors directly in Windows work. You can use the well-known function of rolling back the OS to a time when everything worked fine. To this end, you only need to take a few steps:

1. Through “Start” open the “System Restore” window;
2. Select a restore point and roll back the system.
3. Restart PC.

Most common difficulties

Often, such difficulties appear when users entered network settings incorrectly or due to computer infection malicious applications. Therefore, it is recommended to make sure that the anti-virus databases of the installed utility are up to date and that the firewall is active.

Sometimes problems appear due to incorrectly entered parameters in the interface of your router or banal omissions of some items in its settings.

192.168.1.1

Beginner users of high-speed Internet access, due to their lack of any experience with computer networks, periodically encounter various problems that a more experienced user or IT specialist would solve “one or two”. One of these common problems is the error: DNS server is not responding. The most interesting thing is that Internet access itself usually works fine, Skype and ICQ also work, but the pages in the browser do not open. What to do?

Let's first figure it out - what kind of server is this and what is it for?!

What is DNS, how does it work?!

As you already know, the names of sites on the global page are written in letters so that they can be easily read and subsequently easily remembered. But the computer network itself (both local and Internet) is built on digital IP addresses. That is, behind a beautiful symbolic name there is a set of numbers hidden.

So, DNS (from the English Domain Name System) is a complex step-by-step hierarchical system that stores all the information about the symbolic names of nodes on the Internet and quickly allows you to convert an address from one type to another. For example, you want to go to the website privet.ru and enter it in the browser. Your computer sends the DNS server a request like:

"What is the IP address of the site privet.ru?"

DNS checks information against its database or contacts higher-level servers. The resulting result will be like this:

"The site privet.ru has an IP address of 190.16.99.134"

It is sent back to the computer that sent the request. Thus, if the DNS server does not respond or there are some problems with it, then the user will not be able to open any site or page. And yes, Internet access itself will work great, like all programs that access hosts directly via IP. But the browser will not open the page. If the DNS server does not respond, then in the browser Google Chrome(and all others on this platform) will display the error: net err name not resolved. Example:

That is, the browser cannot perform the resolv operation - that is, it cannot convert a letter address into a digital one and displays the message "Name not resolved".

Let's look at what options there may be to solve the DNS problem.

If the DNS server does not respond, change it!

Each more or less large provider has its own DNS servers. And all network settings are made in such a way that when a subscriber connects, he automatically receives everything he needs to work. Including addresses required servers. But here stable work Not everyone can boast. Some telecom operators generally leave their DNS at the “as is” level, without paying due attention to it. But in the end, it works very poorly, problems constantly arise with it and it crashes, causing users to receive errors like “The DNS server is not responding.” The use of public servers from the largest IT companies in the world will help solve the problem. I prefer to use public servers Google:

Or from Yandex:

77.88.8.8 77.88.8.1

How to register them in Windows 10?! Very simple! Click the Start button and open Operating System Settings. We need the "Network and Internet" section:

In the menu on the left, you need to select the type of connection through which you access the Internet, and on the right, click on the link “Configure adapter settings.” A window should open " Network connections Windows":

Right-click on the connection icon and select “Properties” from the menu that appears. The following window will open:

Here you need to find and double-click on the line “IP version 4 (TCP/IPv4)” to open the Internet Protocol properties window:

Here you need to check the “Use the following DNS server addresses” checkbox at the bottom of the window. After this, two fields below will become available, in which you need to enter DNS IP addresses. Above you see an example with Google servers, and below - from Yandex:

After that, click on the OK button to apply the changes. Now we launch the browser again. The "err name not resolved" error should be resolved.

The antivirus has blocked DNS and it is not responding!

In some cases, the cause of problems with access to the Internet is an overly active antivirus, or rather its network module - Firewall or Firewall. He may not like any request and will easily block access to a particular site on the Internet. Or, alternatively, it can block the work Windows DNS client and he will not be able to send or receive requests, which means the normal operation of the PC on the global web will be paralyzed and the error “DNS server is not responding” will start to appear.

Therefore, when such a picture appears, for diagnostic purposes, it is worth trying to briefly disable the Firewall of the antivirus, as well as the Web Anti-Virus module, if it is present in your security system.

In the case where your Firewall is installed separately, you must also suspend its operation for the duration of the diagnostics.

If after this the problems with the DNS stop and the sites begin to open normally, the reason must be looked for in the firewall rules. By the way, don’t forget to turn it back on, otherwise you risk getting a number of other problems due to network activity malware.

Windows DNS client does not work

For how the operating room Windows system contacts the DNS server, a special network module - the DNS client - responds. He is the one responsible for sending and receiving requests for domain names. But sometimes it can start to fail. First you need to restart it. Right-click on the computer icon on the desktop and select the “Manage” menu item:

In the “Computer Management” window that opens, select the “Services” section. On the left will be displayed full list all available system windows services 10. Find the DNS client line in it:

We check that the status column has the value “Running”. After that, right-click on the line and select the “DNS client” item. In the menu that appears, select "Restart".

Note: If the client is disabled or suspended for any reason, you must enable it again. To do this, double-click on this line to open the service properties:

We check that the startup type is set to “Automatic”. After that, click on the “Run” button. Checking Internet access.

When all else fails

If, despite all the steps taken above, your pages still cannot open, your browser writes “net err name not resolved,” and Windows throws up the error “DNS server is not responding,” then a global failure of the operating system is most likely to blame. To finally verify this, try connecting another PC, laptop or tablet instead of your computer. If everything works perfectly on it, then only windows recovery. To use it, go to windows settings 10 and select the "Update and Security" section:

Here you need to go to the "Recovery" subsection and find the item "Return the computer to initial state". Click on the "Start" button and follow the instructions of the wizard. After the procedure is completed, you will receive a working operating system with it completely restored to its original state system files. You can check Internet access.

How to solve DNS server problems

Before you find out why the DNS server is not responding or unavailable, as well as solving other problems with it, it is important to get information about the server itself or refresh your memory if you have dealt with this before. The DNS server is designed to provide information, communication between computers on the network and other similar operations. The abbreviation DNS itself stands for Domain Name System, which means their totality. For clarity, let's look at a small example.

Sometimes there may be problems with the DNS server, but they can be solved if you follow all the instructions

Let's imagine that all computers on the network are people who are assigned a number at birth (for a PC on the network this is an IP address). For even greater understanding, we will assume that the address in question belongs to some site. So, so that people don’t get confused with numbers, they give each other names. In our case, this will be the name of the site, that is, what you type in address bar browser. But people understand names, but machines need numbers, which is why IP addresses exist. Thus, to ensure this exchange between alphabetic and digital data, a domain name system was invented, which stores in its memory the correspondence of IP addresses and site names. If you access www.google.ru, for example, and the DNS server at your Internet provider has fallen, then you will not go to the site, but will see an error warning. Now, if we understand a little about the essence of how this service works, we can move on to solving the problem.

Can't find address

What to do if you can’t find the DNS server address? This problem is also very common, but there can be many reasons for its occurrence. Therefore, we will consider the most popular:

1. First, be sure to check the operation of your router (that is, there may be a problem with the connection you are using). You can reboot your Wi-Fi router or a wired modem, then try logging into the site again.
2. Secondly, you may experience a failure on the provider side, then you should contact them directly. This will significantly save your time and nerves.
3. The browser used to access the Internet is also important, which may also be the reason why it is not possible to resolve the DNS server address. Try using a different program or application.
4. If problems occur only on one of your devices, then you should definitely correct its settings. First, you can try to check whether the client service itself is running. Launch Control Panel on your computer or laptop. Open the “Administration” item, where, in turn, launch “Services”. In the “General” tab, check the following parameters: startup type should be automatic, status “Running”. If it is turned off, then click the “Run” button in the same window.
5. If you cannot find the server address on only one or two sites, then it is likely that the error lies in the site itself. Then it will be enough to wait some time until the work is restored. It's also worth trying out on multiple devices. If the problem occurs at all, then we turn to the second point above.
6. If the above methods do not help, try using Microsoft utility FixIt, which can be downloaded for free from the official website (http://support.microsoft.com/kb/299357/ru). It can also help if you are unable to resolve the server's DNS address.

DNS server is not responding

So what should you do if your DNS server isn't responding? Now we will solve this unpleasant problem. Please note that this solution is also suitable if the server's DNS address cannot be resolved. We will look at several ways to eliminate this problem, since, unfortunately, there is no single “life preserver”.

Switch to DNS from Google

1. First, you will need to clarify the question: is the DNS client running on your device (computer or laptop)? For this purpose in search bar“Start”, write “Run” and run the found utility. In the field of the window that appears, enter services.msc. Now, in the list of services that appears, find the client we need. If it has an automatic startup option and operating status, then move on to the next point. Otherwise, set these items according to the specified criteria.
2. Next, you will need to switch to public domain name systems from search giant Google. The only thing you should pay attention to is that when working with some providers, redirection to a page with a notification about the end of funds in your personal account may not work. But if this is not a critical problem for you, and correct work server is more important to you, we will describe to you how to do this.
3. Launch Network and Sharing Center in your computer's Control Panel. Open the “Change adapter settings” tab, where you need to select the one from which your Internet works. If you have both a wired and wireless connection, then configure both adapters just in case to avoid conflict situations.
4. Right-click on it and in properties select “Internet Protocol Version 4”, where we will also need properties.
5. In the "General" tab, enter the following parameters:

• The preferred DNS server will be 8.8.8.8
• The alternative will be the following: 8.8.4.4

1. Click OK and close all settings. Check if the problem is resolved. Usually, in most cases, switching to Google's DNS helps when the DNS server does not respond or the server's DNS address cannot be resolved. Therefore, we hope that everything was resolved successfully for you too.

1. Network problems. You need to check that the server has an active allowed connection: check the client’s hardware settings, as well as their serviceability. Make sure you can communicate with other devices or modems that are on the same network as the DNS server. To do this, you can easily use the ping command.
2. If the previous solution did not help, then you need to do additional check. Using the nslookup command, check the ability of your server to respond to clients themselves if the DNS server does not respond.
3. It happens that the browser writes that it cannot find the address. It is possible that the IP address you are interested in simply needs to be added to the list of restricted interfaces for the server (addresses allowed for servicing). This solution will help those users who had a setting on the server to limit the IP addresses that need a response.
4. Be sure to check your computer for viruses or malicious codes using a special antivirus utility. Very often, computer or network problems arise due to viruses on your PC or laptop. Therefore, do not omit this item under any circumstances and conduct a deep scan and, if necessary, clean up of infected files.

Conclusion

Dear friends, today we learned how to solve several problems, namely, what to do if: the DNS server does not respond or is unavailable, you cannot find the DNS server address or convert the DNS server address. We hope that you were able to resolve this issue and it no longer torments you with its presence. Please note that most methods are suitable in almost all cases, so try using universal solutions first and then specific solutions.

Windows, just like any other operating system, can experience errors. Here is an example of one of these errors: “The computer settings are configured correctly, but the device or resource (DNS server) is not responding.” In this case, it is impossible to connect to the Internet. How can you solve this problem?

I want to say right away that I will only describe possible solutions that can help. Each situation must be considered separately.

Possible solution

So, the first and simplest solution is to . To do this, unplug it from the outlet and wait about 10 seconds. In this case, all warning lights on the device will go out. After the specified time, connect the router to power and wait a while until it connects to the network.

If the above method does not help, then you need to use the command line, with which you can clear the cache of some parameters. Run a command prompt as an administrator: click the “Start” button, and in the “Search programs and files” line write cmd. A program shortcut will appear at the top of the window. You need to right-click on it and select “Run as administrator”:

ipconfig /flushdns

ipconfig /registerdns

ipconfig /release

Enter each command by pressing the Enter key after EACH one.

It may be a problem with the TCP/IP settings if certain DNS server addresses are set. This actually happens, but with some types of connections you need to register strictly the DNS addresses that the user receives from the provider. Be extremely careful.

In the control panel, select the “Network and Sharing Center” section, opening which you will see basic information about the network. On the left side of the window, select “Change adapter settings.”

Select your connection, right-click, click on “Properties”.

In the new window, select “Internet Protocol version 6 (TCP/IPv6)” and “Internet Protocol version 4 (TCP/IPv4)” in turn, and click on the “Properties” button.

Check the boxes “Obtain an IP address automatically” and “Obtain a DNS server address automatically.” Click OK.

I repeat once again that you need to be extremely careful with these actions, because if the connection requires a specific IP address and DNS addresses, the Internet will stop working altogether until you enter the addresses that your provider gave you. All responsibility for this falls on your shoulders.

By the way, if the solution for obtaining automatic addresses helps, you can register Google’s DNS servers: 8.8.8.8 and 8.8.4.4, which, as Google itself assures, provide faster loading of web pages by increasing the efficiency of data caching, as well as improved protection against spoofing.

Do you have alternative solutions? I will be glad if you share them in the comments.

There are situations when computer users are faced with the fact that their Internet does not work. One of the most common reasons Why this happens is the “DNS server is not responding” error.

Inexperienced people immediately panic, but this should not be done. The article will describe this problem in detail and suggest ways to solve it.

To fix the problem, you need to learn more about the error that says the DNS server is not willing to respond. . First you need to understand what a DNS server is.

This is a specially designed tool that redirects requests received from the client from a computer or laptop to the Internet domain of interest. When a user accesses any page located on the “global network,” he gains access to a specific remote server, or rather, to one of its sections containing the necessary data. For convenient viewing and scaling they are converted to text view using built-in browser mechanisms.

Any remote server, regardless of its subject matter or place of registration, corresponds to a specific IP address. When sending a request from a computer, the client addresses this address. Sometimes a situation arises when the browser does not display necessary information. This is the desired “DNS server is not responding”, and the error in question is displayed on the screen.

Problems with the provider

Most often, DNS server failure occurs because the error originated with the service provider.

Inexperienced users should not panic and take rash actions that could aggravate the situation and lead to additional problems. The only correct solution is to find the support phone number indicated on the pages of the concluded agreement for the supply of Internet services and contact a specialist.

After this, the wizard will ask you to provide the data necessary to determine the cause of problems with the DNS server:

• first and last name of the subscriber;
• number of the concluded contract;
• time of failure, etc.

If the problem is technical and is on the side of the Internet service provider, the provider’s representative will report this and indicate an approximate time frame for correcting the situation. In general, technical specialists are competent people; in any case, they will give advice on what to do next.

If the provider is “not to blame”, but the device or specific resource gives an error: “DNS server” is not responding , will be checked by a special service responsible for correct work DNS servers. It is not difficult to find it in all Microsoft operating systems. Windows 7 contains it in the Services section.

1. To do this, after right-clicking on the “My Computer” shortcut, select the “Management” sub-item.
2. The window that opens shows the “Services” section, click on it, find the one required by the user, which has the word DNS in the name.
3. Next, right-click to select the startup type “Automatic”.
4. Then, for security, select the “Recovery” tab, where the service is set to restart if problems occur.
5. Windows 10 contains a Services tab in the Task Manager.

Ways to resolve the error

A problem in which it is not possible to contact a remote server due to problems with DNS occurs either on one Internet resource, or when trying to simply connect to the “global network”. Many users are interested in how to quickly fix a DNS error. .

The problem is being solved in different ways, the main thing that is done to successfully correct the situation is to determine the reason why the DNS server on Windows experienced failures.

The first way is when DNS fails , is to change the current DNS server settings. The easiest way to install servers is Google, the largest Internet company in the world. They are guaranteed to work; a situation in which DNS cannot be found is excluded.

• Next, you need to go to the “Network Control Center”.
• To do this, just click on “Start”, then find “Control Panel”, go there, select the desired item.
• You can also right-click on the wifi icon at the bottom right of the screen and select the desired item.
• Determine the section where the adapter parameters are changed.
• Find an existing Internet connection.
• In its settings, the checkbox responsible for automatically obtaining DNS server addresses is removed. Fill in empty fields addresses provided by Google: 8.8.8.8 and 8.8.4.4.

Another way to fix DNS server error is to clear the cache. The easiest way to do this is through the command line.

1. Opens by pressing two Windows keys and R.
2. Then the field is filled with the cmd value and the OK button is pressed.
3. Several commands are entered: ipconfig/flushdns, ipconfig/registerdns, ipconfig/release, ipconfig/renew.
4. After this, restart your computer.

Based on the results of these manipulations, there should be no problems with the DNS server.

Antivirus blocked DNS

In some cases, DNS failure is caused by the fact that the Anti-Virus installed on a laptop or computer blocks the ability to access DNS. This happens for several reasons. Sometimes a computer is infected with a virus that blocks the ability of DNS to work, but most often the antivirus software incorrectly configured. It is capable of “not allowing” access to a certain resource or even completely blocking DNS in the operating system. The Anti-Virus is disabled for 10 minutes. At this time, you need to go to the browser and try to go to some site. If everything is successful, then you should look for an error in the settings of other security software parameters.

Sometimes the cause is a firewall. Moreover, it is blocked by the pre-installed firewall of the operating system or the one built into the Anti-Virus. To check, it is enough to temporarily disable it, similar to Anti-Virus. This is done in the “Control Panel” in the “Security” section.

In some companies and organizations, firewalls, antiviruses and networks are configured by system administrators in such a way as to prevent employees from visiting third-party sites. These include social networks, torrent trackers and other types of entertainment Internet resources that distract from work. This is done, among other things, by blocking the DNS server. To solve the problem, portable configuration programs and anonymizers are used.

Updating network card drivers

The DNS server often does not work in Windows 10. This is the latest system, sometimes causing errors due to the use of old drivers installed for the network card. The problem can be easily solved through specialized applications like Driver Booster. It is enough to download it from the official website, install it according to the available prompts and run it. After this, the program will find problem areas, redirect the user to download drivers from the “global network”, and help install them.

However it is not difficult to do in the usual ways, preinstalled in the operating system. To do this, open “Device Manager”, find “ Network card" Having found out the name, download required driver, and then click "Update".

The most common problems with DNS servers are problems that occur on the router. In order to determine that it is he who is “to blame,” a computer or laptop is connected directly to the cable installed in the apartment by the Internet service provider. If everything works, the DNS server is blocked by the router. The easiest way to solve problems caused by the router is to reset the settings to factory settings. Depending on the model and manufacturer, this is done in different ways. Sometimes it is enough to hold down the WPS/RESET button or insert something like a needle into a special hole. If desired, the router can be configured from the inside, for which you need to go to the address 192.168.1.1 and solve the problem in the administrator interface.

When all else fails

If none of the above methods corrected the situation, the DNS error is still displayed, there is nothing left to do but call a specialized specialist.

The easiest way to do this is to contact the company with which the user has an agreement for the supply of Internet services. A technician will come from the provider, who will set up and fix any problems for a fee.

When an error appears on your computer indicating that the DNS server is not responding, there is no reason to panic. There are many reasons leading to failure and solutions to fix it.

Sometimes after rebooting the computer, or even for no obvious reason, instead of home page favorite site, a frightening message “Dns server address not found” is displayed (sometimes the message is even more succinct “DNS server error”).

And in this article we will look at why the dns server does not respond, and what to do when Windows OS cannot find the dns address of the server.

Cannot find server dns address: possible causes of the problem

Among the most common causes of DNS server errors are:

1. Technical work on the site itself or on the side of the ISP that “hosts” the Internet resource.

2. Technical work on the side of your Internet provider.

3. Network settings on your computer have failed.

If a DNS server error “pops up” only on one site (and the rest of the web pages “load” without problems), then the problem is most likely on the side of this web resource and there is nothing you can do here: for sure, site administrators know about problems and will fix the problem as soon as possible.

If the DNS server is unavailable on several sites, then it is worth checking the loading of these resources from other computers/mobile devices: if the unfortunate error occurs on all PCs, then this is either a problem with the provider or a problem with your network device(for example, a router).

In this case, you should trust the complex network magic using auto-tuning and:

1. Turn off the power to the router, wait 30 seconds and turn on the router again.

2. Take out network cable from the LAN port of the computer and reconnect the connector to the network card connector.

3. Restart your computer.

In most cases, after such “operations” Windows is able to find the dns address of the server, and your favorite sites work without problems.

If the browser still writes that the DNS server is not responding, then you will have to “uncover the heavy artillery.”

There are several other possible reasons for this error:

1. Viruses that automatically change network settings Windows 7 OS.

2. An unlucky wizard who manually set .

3. DNS settings that are broken after removing any system/network programs or problems with automatic start DNS services.

How to fix the “DNS server unavailable” error?

1. DNS cache is a data storage on your computer in which the names of sites are recorded - this is necessary to speed up the connection to the desired resource. Perhaps clearing the cache will help - to do this, press “Win” + “R”, run the command “ipconfig /flushdns” in the terminal and try to access the site again.

2. If updating the cache did not help, you will have to manually register the DNS servers - most likely, these are problems on the provider’s side. To do this, open the command line terminal again via “Win” + “R” and execute “ncpa.cpl” - the “Network Connections” menu will open.

2.1. Select the one that is used to access the network -> Properties -> Internet Protocol Version 4 -> Properties.

2.2. If something is indicated in the “Primary” and “Alternate” servers, try checking the “Receive DNS data automatically” box, apply the changes and reboot.

2.3. If initially there was a checkbox for automatic retrieval, then in the “Preferred DNS server address” indicate “8.8.8.8”, and in the “Alternative” - “8.8.4.4”.

So you indicated Google servers Public DNS that works flawlessly. Apply the settings, restart your computer and try connecting to the desired site again.

If the computer cannot find the DNS server address when connecting through a router (and not directly), you need to find it in the tab with DNS servers and specify the same two addresses there. If there are more fields for addresses or other addresses are specified, do not be alarmed, just specify two addresses and save the settings.

3. If this does not help, perhaps the error appears due to a virus.

In this case, a full system scan with antivirus software, such as Dr.Web, Avira, Avast or Kaspersky, will help.

4. Check if the autostart of the DNS service works correctly. To do this, go to Control Panel -> Administration -> Services,

find in the list DNS service and check if “Automatic” is listed in the “Startup Type” column.

5. If after all the above measures the problem “cannot find the dns address of the server” is not resolved, you will need to reset the TCP/IP settings on the computer. Here you will find free utility from Microsoft and user instructions - https://support.microsoft.com/ru-ru/kb/299357
