• Diagnostics of computer networks using standard operating system tools. Server Maintenance

    Almost every organization in Moscow strives to supplement its office with modern office equipment. Priority tasks in organizing office activities are performed by computers, which often operate on the basis operating system Windows. Microsoft Products have a user-friendly interface, are regularly updated and are perfectly adapted to work with different software.

    To ensure efficient work information systems you can use the server administration services provided by our company. Our company is among the leaders in server maintenance services in Moscow.

    High-quality maintenance of server computers allows you to:

    • reduce costs;
    • ensure uninterrupted and efficient operation of the server;
    • get things going local network;
    • timely adjust the IT infrastructure according to the needs of the company;
    • timely correct breakdowns that may negatively affect the work of the organization.

    Work with the server may include the following services:

    • diagnostics and management of hardware and software;
    • setting up services;
    • installation of programs;
    • remote administration;
    • secure data transfer, security control;
    • current repairs and prevention;
    • optimization of server operation.

    Servers based on Windows OS are maintained using programs Windows Server different years of manufacture. Installing packages of these tools is different from normal installation software on PCs and laptops.

    All Windows tools Server are perfectly adapted for remote administration. Windows program Server 2012 is an improved version and is especially popular. Helpful changes have been made to improve performance and safety.

    New functions improve network diagnostics and simplify the administrator’s work, reducing the likelihood of failure. This system allows you to restore data, as it provides protection against network failures, scales applications and distributes the load between local node and cloud service.

    Remote server administration tools for Windows 10 are no less convenient to use and install than Windows Server 2012, but they can only be installed on computers with Windows 10.

    Remote server administration tools for Windows 10 are designed for Windows 10 x64 and x86 architectures. When installing this type of software, you must remove all old versions of packages and packages for different languages and keyboard layouts.

    Setting up and maintaining computers and servers is a chain of actions that make the company’s work more comfortable. Since the server is connected to the organization’s local network, its breakdown can lead to a complete shutdown of the infrastructure.

    It is best to entrust this work to the professionals of our company, who have the most positive reviews from its clients in Moscow. They will expertly make the necessary adjustments.

    Work with servers is carried out in the following areas:

    • installation and configuration of mail for corporate needs;
    • domain structure maintenance;
    • organizing the work of a proxy server, its modernization and configuration, setting rules for use, restoration;
    • working with fax services;
    • file storage maintenance;
    • backup and restoration.

    Many users periodically encounter one or another network problems. The situations here may be different. For example, the quality of communication may deteriorate and some servers may become unavailable. Such failures can be critical for users of online services, for example, traders trading in the stock market, players in network games etc. It happens that after changing some settings on the computer or changing the provider, it is not possible to access the network at all, and when setting up home network, for example, it turns out that only one of the computers has access to the Internet, etc. In many such cases it is necessary to carry out diagnostics network connection and check the performance of a particular remote node.

    ⇡ Built-in Windows tools - Ping and Tracert utilities

    OS Windows has several utilities for diagnosing network status, but the most commonly used are Ping and Tracert. The Ping program sends a request to the specified network node and records the time between sending the request and receiving the response (RTT, from the English Round Trip Time), in other words, the utility allows you to determine the response time of the server of interest. It is clear that the smaller it is, the faster the data exchange with this server is. The Tracert program sends a test packet to the specified host, displaying information about all intermediate routers through which the packet passed on the way to the requested host, as well as the minimum, maximum and average response time of each of them. This allows you to estimate how long the packet has traveled and in which section the greatest delays associated with data transmission occur. What do the results produced by the Ping and Tracert utilities mean? For example, the lack of response from the remote server may indicate that it is currently unavailable, or that the server administrator has blocked echo requests (while other server services may be working normally). If the response time (RTT) of remote servers is too long and does not depend on their location, most likely the quality of your connection leaves much to be desired and you should contact your provider. However, you can get some speed gains by setting up your Internet connection to maximum performance, for which it is better to use special optimizer utilities such as TweakMASTER, but this is a completely different topic. The route to the server of interest is too “long” (that is, large number intermediate routers on the way to connect to the server) often leads to slower communication with it. If this is critical, then it makes sense to try to look for options to reduce the length of the route. For example, in case game servers you can make a choice in favor of those that are as close as possible to the server of your Internet provider. If the utilities show that test packets do not pass further than your provider’s server, it is very likely that problems have arisen on its side, or maybe this is scheduled maintenance work. There are no tricks in using the Ping and Tracert utilities, but technically using them is not very convenient. To run a ping test or trace, you will have to open a command line window and enter a command, possibly with parameters that you either need to remember or refer to help each time. For example, to check the functionality of the www.site site, you will need to enter command line team ping www.site, and to find out the path of packets to a given node - the command tracert www.site. The results of these commands are presented below and are several lines of text. Note that you can also run the specified commands through the “Start” > “Run” menu, but in this case the program window will automatically close immediately after its completion and all results will be lost.

    It is much more convenient to use specialized utilities that can trace the “travel” of packets over the network and report it using the server’s IP address additional information. Such utilities can be very useful for quick analysis and source identification network problems. We will focus on using such utilities in this article.

    ⇡ Diagnostic services

    First, let's briefly talk about alternative network diagnostics - using special online services. Examples of these include WhatIsMyIPAddress.com and Yougetsignal.com, as well as Whois service. Using the WhatIsMyIPAddress.com service you can find out your external IP address if you do not know it or if it is dynamic. You can also see the path of packets between your computer and this server. This is easy to do, you need to select the “Visual Traceroute” function in the “IP Tools” menu, enter your external IP address and click on the “Visual Traceroute” button.

    You can also use the "IP lookup" tool to find out some details about the IP address of interest, including the host name, geographical coordinates and location on the world map. Why is this necessary? Well, for example, to get to the source of an intrusion into your system, if you have detected one. Using the "Visual Trace Route Tool" function on the Yougetsignal.com service, you can also conduct a trace by simply entering the server URL or its IP address and clicking on the "Host Trace" button. As a result, the service will display the path of the packets on a world map, as well as in the form of a list of intermediate servers indicating the total number of transitions and the belonging of each of them to a specific country. By activating the "Network Location Tool" function, you can find out the geographical location of any server by its IP address. And using the "WHOIS lookup Tool" function you can get information about the server from information service WHOIS.

    The Whois service will help you establish the response time of the server of interest (the “Ping” function), determine the path of the request to the server and find out how many and which intermediate Internet servers, routers and other devices are involved in sending data to the server and back (Tracert).

    In addition, using the "IP Lookup" function, you can find out its IP address by the host name (or vice versa), and the "Whois" function will tell you whether the specified domain is free or busy. If a domain is taken, you can identify its owner and how to contact him (if, for example, you want to buy this domain name).

    What is the server for?

    File server

    You have accumulated a lot of files that do not fit on your computer, what if they all disappear? Your employees need general access to files?

    Maintaining computers and servers is an important task for any enterprise, especially large ones. Today, the activities of any company directly depend on computers. Their condition determines the speed of work and its quality. Setting up and maintaining servers is a whole chain practical actions. They can be committed both by employees of the enterprise, which is not always profitable, and by special companies.

    Server Maintenance

    Information security and permanent job systems directly require server maintenance. Maintaining a server requires many steps, such as installation and Before installing the equipment, you need to check it. Afterwards, the server equipment is installed and launched. It is also important to install and configure software. Additional safety equipment can also be installed. It is important to take maintenance seriously, otherwise it may result in loss of information.

    Subsequent operations

    After completing all operations and starting the system, it is necessary to constantly monitor the system parameters and make sure that the batteries, cables, and wires are in good condition. The heating of system equipment, which depends on the proper operation of air conditioners and fans, must also be controlled; it is also important to ensure uninterrupted power supply. A constant supply of electricity is one of the most important points. Therefore, for serious work, it is better to immediately install so-called uninterruptible power supplies, thanks to which system equipment will be able to work even if there is no electricity.

    Server subscription service

    Subscriber service for servers is nothing more than improving the company’s performance by assigning responsibilities for server repair, configuration and service to professionals. A server is a computer equipped with peripherals that allow it to work continuously twenty-four hours a day and process huge amounts of information. The operation of portals and websites on the Internet depends on the server.

    Using the server and the special software installed on it, it is possible to access the Internet, safe storage important and necessary information and even restoration of lost information. It is important to know: the larger the company, the more powerful the server should be, since a large company has many employees. This means that in order to maintain the operation of this equipment it is necessary to provide this work professionals in their field. Often the solution to minor problems is left to private employees, but in more serious cases they still provide repairs. server equipment IT company specializing in this area. Good server maintenance will avoid loss important information and system failures.

    Remote administration

    Let's figure out what remote administration is.

    This is one of the types of server services that involves system management and accounts at a distance. Remote work creates a certain comfort for users. Remote control involves reviewing system logs and troubleshooting for subsequent configuration. Control is underway backup. Also included is the ability to change or update the operating system.

    After server maintenance, there is an opportunity to reduce costs due to the use of IT services. Also, thanks to the use of these services, it is possible to achieve uninterrupted operation of the server, and therefore the enterprise. This will ensure the security of stored information and the ability to obtain it for a certain class of users.

    Terminal servers


    Often there is a desire to connect personal computer to the Internet. Some users want to create a comfortable user network for total control over all aspects of their activities and simplify the process of use. To do this, a terminal server is installed, which stores information from all computers on the network. Typically, the terminal computer is not used for direct work. But if any computer on the network fails, all data can be saved on the terminal server, which allows you to very quickly restore work without serious losses.

    On at the moment many economic entities can afford to have service complexes, but this entails large costs: firstly, for assembly, configuration, installation and technical service, and secondly, for the maintenance of this complex, since it consumes large amounts of electricity .

    Remote server maintenance

    Remote server maintenance is widely used in the activities of any company. Today there are many organizations that can maintain computers and servers remotely. In such situations, a unique type of device is used to ensure communication between remote nodes. For this, a remote access server that can process data different computers, connect to the network. This technology is widely used, as it makes the activities of all kinds of companies easier and more comfortable.

    Remote control and remote nodes are all types of remote access servers. Remote node services have the meaning of connecting users to each other. controls, in turn, transfer data and can also open various files on computers, creating an image on the screen of another computer of this file. They work with the Windows operating system.

    Domain controller server maintenance

    Improving any IT infrastructure is nothing more than customizing the operating system. For example, you can limit access to the Internet - this will greatly improve the productivity of employees. If you want to reduce Internet traffic costs, you need to install an Internet gateway and proxy server. May require full control email correspondence at the enterprise. This is possible when installing letters. There will no longer be a need for the services of hosting providers. If the enterprise needs to organize collaboration with large amounts of information, it is best to configure a database server.

    Server maintenance is essential to ensure that all equipment does not fail, which is extremely important in any enterprise. It also significantly extends the service life installed equipment and prevents sudden failure. You can quickly respond to system errors and effectively eliminate them even from remote access. Therefore, it is absolutely not necessary to keep a highly paid employee on staff. It is much more profitable to entrust server maintenance to a company working in this profile.

    A server is a computer that provides its resources (disks, printers, directories, files, etc.) to other network users.

    The file server serves workstations. Nowadays it is usually fast acting PC based on Pentium processors, working with clock frequency 500 MHz and higher, with volume RAM 128MB or more. Most often, a file server performs only these functions. But sometimes in small LAN The file server is also used as workstation. The file server must have a network operating system as well as network software. Server network software includes network services and protocols, as well as server administration tools.

    File servers can control user access to various parts of the file system. This is usually done by allowing the user to attach some file system(or directory) to the user's workstation for further use as local disk.

    As the functions assigned to servers become more complex and the number of clients they serve increases, servers become increasingly specialized. There are many types of servers.


    • Primary domain controller, the server on which the user budget database is stored and the security policy is maintained.

    • Secondary domain controller, the server on which the backup database of user budgets and protection policies.

    • A universal server designed to perform a simple set of various data processing tasks on a local network.

    • A database server that processes queries sent to the database.

    • Proxy server that connects a local network to the Internet.

    • A web server designed to work with web information.

    • A file server that ensures the functioning of distributed resources, including files and software.

    • An application server designed to run application processes. On the one hand, it interacts with clients, receiving tasks, and on the other hand, it works with databases, selecting the data necessary for processing.

    • A remote access server that provides employees, sales agents working at home, branch employees, and people on business trips with the ability to work with network data.

    • A telephone server designed to organize telephony services on a local network. This server performs the functions of voice mail, automatic call distribution, cost accounting telephone conversations, interface with external telephone network. In addition to telephony, the server can also transmit images and fax messages.

    • A mail server that provides a service in response to requests sent via email.

    • An access server that makes it possible to share resources among users who find themselves outside their networks (for example, users who are on business trips and want to work with their networks). To do this, users via communication networks connect to the access server and the latter provides the necessary resources available on the network.

    • A terminal server that unites a group of terminals, simplifying switching when they move.

    • A communications server that performs the functions of a terminal server, but also performs data routing.

    • The video server, which is best suited for image processing, supplies users with video materials, training programs, video games, and provides electronic marketing. Has high performance And great memory.

    • Fax server that provides transmission and reception of messages in fax communication standards.

    • A data protection server equipped with a wide range of data security tools and, first of all, password identification.

    Topic 5. Network operating systems

    Network operating systems ( Network Operating System (NOS) is a set of programs that provide data processing, storage and transmission on the network.

    To organize a network, in addition to hardware, you also need a network operating system. Operating systems by themselves cannot support networking. To complement some OS network means a network installation procedure is required.

    A network operating system is needed to manage message flows between workstations and file server. It is an application platform that provides a variety of network services and supports the operation of application processes implemented in networks. NOS use a client-server or peer-to-peer architecture.

    NOS defines a group of protocols that provide basic network functions. These include:


    • addressing network objects;

    • functioning of network services;

    • ensuring data security;

    • network management.
