Hardware and software setup

The main dns server is not connected. Can't find dns server address: how to fix? How to change the DNS server: the necessary settings on the video

To digital IP sequences. Thanks to them, we do not have to remember numbers - the real addresses of resources on the network, but rather more understandable letter combinations. If DNS server does not respond, you will not be able to visit the desired site. Let's figure out how to solve this problem.

If the DNS (DNS) server is unavailable, what to do first:

  • reboot the router by turning off its power for 20 seconds or by pressing the reset button on the back;
  • shut down and restart your computer.

After a reboot, the settings are updated and the problem often goes away. If access to the resource did not appear, and you are connected to the network through a router, connect directly. Also check if there is access on other devices.

If the error appeared after installing new programs or browser extensions, disable or remove the applications. Close the antivirus for a while, if you use a firewall and firewalls - suspend them.

Turn on the service in Windows

When the DNS server is not available, it is worth checking the activity of the corresponding Windows client. Hold Win+R and paste services.msc. In the list, find "DNS client", click on it right click mouse and open "Properties". The startup type should be here - “automatically”, if you have something else selected, change it.

Click "Run" and save the settings. In the end, it's better to reboot.

Changing connection settings

When the DNS (DNS) server does not respond, in Windows OS you can change network settings:

  1. click in the tray next to the clock on the network icon, launch "Open Settings";
  2. at the bottom, under the connection status, go to the "Network Control Center ...";
  3. among the settings, select "Change adapter settings";
  4. select your connection in the list and open its properties;
  5. go to "IP version 4" and select "Properties" again;
  6. move the checkbox to automatic receipt DNS addresses.

Another option on how to fix the unavailability of the server is to write addresses from Google in this form. Move the checkbox to "Use the following addresses ..." and enter the values ​​\u200b\u200bof 8.8.8.8 and 8.8.4.4, respectively, as the preferred and alternative servers.

If these settings helped determine the DNS server, they can be specified in the router settings so that there are no access problems on all devices. In the router management interface desired values look in the WAN or Internet sections. On Mikrotik devices, configuration is carried out in the Winbox application: launch IP in the menu, then DNS, enter the address in the window, you still need one more - click on the down arrow.

Uncheck "Allow remote request" and save everything.

Clean up network settings

Sometimes the DNS server does not respond due to incorrect parameters in the address cache. Windows 10 has a handy cleanup utility that resets all OS, adapter, and network card settings to factory settings. To start the reset, launch the settings in the "Start" and select "Network and Internet". On the first tab, scroll down to the "Network Reset" item. Confirm the action and wait for the reboot.

In early Windows versions you can reset the settings from the command line by running it as an administrator. To do this, copy and run one directive at a time:

  • ipconfig /flushdns
  • ipconfig /registerdns
  • ipconfig / renew
  • ipconfig /release

The DNS cache will be cleared sequentially and the IP protocol will be reconfigured.

If only some sites are blocked

If the Internet connection is working fine, and the error with incorrect DNS appears only on certain resources, this means that they have been blocked by the provider or network administrator. Often this occurs on a work computer, when trying to access a social network or entertainment portal.

You can get around this restriction - to visit closed resources, use anonymizers or VPN. Anonymizers are sites that mask banned addresses. VPNs work in a similar way - you can install them in your browser as a corresponding extension or use Opera, which has a built-in VPN function.

Conclusion

We figured out how to solve the problem with the DNS server. If a simple reboot of the devices does not help, proceed to changing the settings in Windows. The last resortfull reset network settings, it will clear all changes, returning them to the factory state.

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 obscure addresses like 147.15.28.677. This mechanism is implemented both on the provider's side (with the help of DNS servers) and on client equipment by special services and services of the operating system. Also, additional DNS support can be provided by the client's communication equipment: a router, access point, or 3G modem. Domain Name Service (DNS) problems for the average user are tantamount to a failure of the Internet channel, since he cannot open web pages. Therefore, it is very important to understand what problems can occur in the operation of DNS services and how to quickly resolve them.

Causes of DNS Errors

Domain name servers (DNS) are an important element of the Internet infrastructure. It is they who convert the symbolic name of the site into an IP address, through which access takes place. As a rule, such servers are part of the hardware and software complex of your Internet provider, but there are also alternative sites that can be accessed by the appropriate settings of the network adapter or home router. Since the DNS server is an ordinary computer(or a cluster of computers), then it may “hang”, be infected with a computer virus, or 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 in the Internet browser window you will see a message similar to the following:

A message of this kind indicates a problem with the DNS system.

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

The first thing to do when encountering a DNS addressing error is to check the DNS settings in both the network connection properties and the control panel of your home router. If the ISP's DNS server is down, you can connect to one of the alternative DNS servers and restore the Internet channel. To do this is easy.

In operating systems Windows 7, 8, 10

In OS family Windows settings DNS are 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 command prompt window, open the Network Connections snap-in.

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

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

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

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

    TCP / IP protocol - the basis for connecting to the Internet and DNS settings are located in its settings

  4. DNS settings - two fields at the bottom of the window, for the primary and alternate 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, enable the "use the following DNS server addresses" mode

  5. To use an alternate 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 the blocking of some sites that the provider has introduced or System Administrator enterprises

  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 unprepared user. Having learned how to change the DNS server settings on one router model, it will not be difficult to do this on others.

In order to access the web interface of the router, you need to find out its network address. This can be done using the ipconfig command, by calling it from the command line. The "default gateway" item displays the network address of the router. To access the web interface of the router, you need to enter this address in an Internet browser.

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

Having opened the web interface, we will add the addresses of the DNS servers to the settings. Let's do this using the example of the settings of a router of the widespread TP-Link family.

  1. After entering the router address, we get to home page its web panel. Usually this is the status page.

    On the start page the web panel of the router displays all the basic settings

  2. Go to the "Network" section, to the "WAN" tab. Here are the settings for connecting to the Internet provider. If the connection type is “Dynamic IP” (Dynamic IP) or “Static IP” (Static IP), then you can specify the DNS server addresses 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 type of connection to the provider is "PPPoE", "PPTP" or "L2TP", it is better to configure the DNS servers in the DHCP section.

    You can also specify alternative DNS server addresses in the DHCP settings.

Scanning the system for viruses

The category has been around for a long time. computer viruses specializing in the theft of personal data of users. One of the tactics of 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 e-wallet to specially created false copies, with the help of which passwords are stolen, electronic keys and even two-factor authentication options.

If your frequently visited pages did not open the first time, with a long delay or did not open at all, and the website of the banking program began to look a little different, there is a reason to stop authorization attempts, disconnect your computer from the Internet and conduct a full system scan using antivirus program. Although there is a large number of shareware and free anti-virus packages, you can count on real protection only using the first-tier commercial anti-virus 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 Internet activity control modules and will be able to nip in the bud the attempts of virus programs to establish control over your system.

NOD32 antivirus package provides real-time protection against a wide range of viruses

Configuring antivirus and firewall

With rare exceptions, the settings of the anti-virus package and the firewall (firewall) should not lead to disruption of the DNS services. The reason for this can only be a change in the settings of the "expert" mode by an 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 "defaults".

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

Update network card drivers

Installing the latest new network adapter drivers will help your Internet connection work more efficiently, provide fast access to DNS servers and eliminate errors that occur when opening web pages.

  1. Using keyboard shortcuts call 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 context menu that opens, select the "Update drivers ..." item and wait for the update to complete.

    Run procedure automatic update drivers

Automatic updating of network card drivers will be possible only with a working Internet connection.

Restarting the computer and router

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

Computer restarts standard means operating room Windows systems. It is enough to select the shutdown icon from the Start menu and select the "restart" item from the drop-down list.

Restart your computer using the Start menu of your operating system

The router can also be restarted using the corresponding section of the web interface, but more in a reliable way there will be a power reset: turn off the device using the switch on the rear panel or by unplugging its AC adapter from the outlet. 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 power adapter from the wall socket

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:

The "Services" window allows you to view the status of services and services of the system, as well as stop and start them

  • In the properties window, verify that the service is running and functioning correctly.

    The properties window of the DNS Client service allows you to restart it in case of failure or error

  • If the service is not running, it must be restarted. By successively clicking on the "Stop" and then "Start" buttons, you will restart the "DNS client" service and restore its normal operation.
  • Clearing DNS cache and other network settings via command line

    With active Internet surfing, a significant amount of data about the addresses of visited resources is accumulated in the DNS cache. Using a DNS cache instead of a DNS server should improve page opening speed, but in practice the data in the cache can become out of date and the page can no longer be opened. In this case, the DNS cache needs to be flushed, which is easy to do using the Windows command line tools.

    1. Holding down 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. Type netsh winsock reset and press Enter.
    8. Reboot your computer.

    Nothing helps: what to do

    If all your attempts to "reach out" to the necessary sites have not been successful, then the problem is on the side of the Internet provider. In this case, it remains to rely only on the promptness of the service technical support and the qualifications of service engineers who will resolve problems as quickly as possible. By and large, calling the ISP's hotline should be the first thing a user does when their web pages stop opening.

    If the availability of an Internet channel 24 hours a day, seven days a week is vital for you, it's a good idea to take care of a backup channel that will provide for your needs while the main one is being prevented. You can implement it by linking a wireless router with 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 not available.

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

    The domain name mechanism (DNS) is one of the most important, as it provides that level of transparency and comfort, without which the Internet would remain a 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 old window with an annoying error.

    The problem of unavailability of DNS servers can become a pressing problem for every person who has access to the Internet. DNS technology is required in order for the browser installed on the device to function correctly and transmit information.

    Modern routers have automatic retrieval of server information. And such a problem as the DNS server does not respond should be absent.

    To solve the problem, you need to run troubleshooting and wait a while until the cause is found.

    After the troubleshooting wizard finishes its work, you need to restart your computer. Then, go to the required resource and wait a while.

    If the problem persists, look for the network connection icon. If it displays Exclamation point, check your internet balance or contact your ISP.

    To fix a problem with the DNS server, you must:

    • If the DNS server is not responding, check if the service responsible for connecting to servers on your computer is running;
    • Go to the public servers provided by the Google search engine.

    To fix the server connection problem, you can do this:

    On the keyboard, you need to type the command "Win + R". After the working window is displayed, you need to type the services.msc command. A list of system services will appear, we are looking for a DNS client. Then, you need to check the startup type, it should look like this: Startup type - automatic, status - connected. If the status indicates that the service is in connecting status, wait a while. If the problem persists, go to the next step.

    We switch to public servers provided by search engine Google.

    If the DNS server does not respond too often, it will be enough to go to public settings. Unlike those servers that the provider provides, they have no problems and work constantly.

    Click on the start icon, control panel, network and sharing center and public access, change adapter settings. Next, you need to select the network adapter that is used to access the Internet. If the problem appeared on a laptop, you need to configure both devices to access the Internet via wireless network, and a regular Ethernet port.

    Right-click on the network adapter icon, open properties. Next, you need to open Internet Protocol version 4 and click on the properties tab. Go to the general tab, and in the DNS server lines, enter the following values:

    • The first field must be entered - 8.8.8.8
    • Second field - 8.8.4.4

    Push the button "OK". Your device is now set up to receive information using Google's servers. The method is intended for such operating systems like Windows 7, 8 and 10.

    Automatic configuration with DNS JUMPER

    There is a method for automatically configuring servers. It is suitable for all operating systems, including XP and VISTA.

    Additional software is required to perform automatic configuration in order for the DNS server to start responding. One of the most requested programs is DNS JUMPER. It can be found for free.

    To fix the problem with the unavailability of various resources, just open DNS JUMPER and press the button " Automatic tuning". Then, you need to wait a while and after the process is completed, restart the PC. If an error occurs at this time, close the program and repeat the above steps.

    Sometimes, when trying to load a site, a message appears " DNS server not responding" or something like that. The error can occur both on one particular site and on every page you try to open. About problem can be fixed different methods, depending on the cause of its occurrence.

    ISP side problems

    DNS settings are automatically downloaded when the computer is connected to the network. Some companies provide all the necessary data so that the user can enter it manually, but this approach is becoming less common. If you enter settings IP and DNS manually, then check if they have gone astray. Restart your computer and router if you have one.

    DNS- server still not responding? Then call your ISP, maybe they have problems with the server. If the technical support operator does not find problems on their side, then the problem is most likely with you.

    The DNS server is not responding. How to fix?

    Reason for the error DNS may be hidden in the browser settings. Download some other browser and try to open the site in it. If the error has disappeared, then you should reinstall the problematic program or switch to the one that works. In some cases DNS refuses to work on all browsers. Therefore, the problem is in the computer settings or in the activity of some program.

    Go to "Network Connections" and look for suspicious connections there. Sometimes an unscrupulous application creates one or more new Internet connections that interfere with normal operation. Disconnect all obscure connections and check if it works DNS. If this does not help, then boot the system into safe mode and try to open the site. Is everything working fine? So, boot into normal mode and enter the task manager Windows. Close one application after another until DNS won't work. In this way, you can identify a program that interferes with the normal loading of web pages.

    Router problems

    Common reason why DNS server is not responding- failure of the router. First of all, reset the router settings using the button reset . It usually hides in a recess on the back or bottom of the case. Take a paperclip or a needle and hold down the button for a few seconds. Set up your router again and try to open a website.

    Error in place? Then, to eliminate the problem with the router, connect the power cord to the computer directly. Sometimes this requires you to call the provider to make the connection work. If the problem persists with a direct connection, then the reason lies in the computer settings.

    Google DNS servers

    One of the methods to solve the problem with DNS- set servers in settings Google. They work quickly and without failures, unlike the servers provided by telecom operators. To go to DNS from Google go to the "Control Panel" and select the "Small Icons" option in the "View" column. Go to "Network and Sharing Center" and find the "Change adapter settings" button there. There, look for a valid network connection, right-click on it and go to properties.

    A menu will open in which you should select the item "Internet Protocol Version 4". If you check the box "Get address DNS- server automatically", change it to "Use the following addresses DNS- servers". Then enter the server addresses from Google- 8.8.8.8 and 8.8.4.4. After saving the changes, the problem will most likely disappear. This method is well suited for bypassing the blocking that providers set. If you want to go to your favorite torrent tracker, but it is prohibited, then DNS servers from Google can help.

    Other means of solving the problem

    Windows has special tools for troubleshooting. They rarely help, but can be useful if the DNS server is not responding. To launch the diagnostic wizard, right-click on a valid Internet connection and select "Diagnostics". The wizard will try to fix the error step by step, constantly asking if the problem is gone. As a rule, if DNS- the server is not responding Windows unable to automatically fix the problem, you have to solve it manually.

    Sometimes in systems Windows the service responsible for working with DNS. To check if everything is fine with it, right-click on "My Computer" and go to "Management". There, open Services and Applications and select Services. A list will open in which you need to find DNS- customer. Make sure the service is running and also check if it is configured to autostart. Right click on DNS- client and select Properties. There, find the "Startup Type" option and set it to "Automatic" if there is any other startup option. Then open the "Recovery" tab and configure there to restart the service on each failure.

    Sometimes if the DNS server is not responding, then you just need to clear its cache so that everything falls into place. To do this, you need to go to command line. Press key combination Win+R. A line will appear "Run", in which you should enter cmd and press Enter. Then you need to type 4 commands, one after the other: ipconfig/flushdns, ipconfig/registerdns, ipconfig/release, and ipconfig/renew. Then restart your computer and check if it works DNS.

    Blocking social networks in enterprises

    Large enterprises block access to entertainment sites for their employees. Social networks take a lot of work time from office workers, so administrators block them on the server, as a result of which you can stumble upon the error “ DNS- the server is not responding." What to do in this situation? Especially for office workers suffering without a loved one social network, anonymizing sites were invented that allow you to get the forbidden fruit.

    The anonymizer converts a standard web page address into a character set. As a result, the server lets the user through to the forbidden portal, since a different address is used when connecting. Some anonymizers can be blocked by the network administrator, but, fortunately, there are so many of them that it is unlikely that a cunning administrator will be able to block everything.

    If sites to bypass blocking do not help, then you can use one of the proxy servers. Choose a server from nearby countries so that the connection is fast. As you can see, DNS issues -server can be easily eliminated on your own. If none of the methods helped, then you should contact a specialist.

    It is impossible to imagine our existence without access to information sources provided by the Internet. DNS servers are the connecting link in a network of computers. Unfortunately, sometimes errors occur in their work. In these cases, access to the Internet is limited or non-existent. Therefore, each user will not interfere with basic knowledge on the topic.

    What is a DNS server, why errors may occur

    If you explain in simple words, you can call the DNS server the address book of the Internet. Each computer connected to the network receives an IP address identifier in the form of a numeric value similar to this - 127.0.0.1. Each published site has Domain name- http://hostus.ru. The main task of a DNS server is to convert (translate) a domain name into IP addresses and the reverse process.

    Video: explanation of how the DNS server works

    Unfortunately, sometimes there are failures in the chain. Errors occur. There can be quite a few reasons, consider the most common:

    • no internet connection;
    • incorrect router or modem settings;
    • incorrect firewall settings;
    • critically outdated network card driver;
    • computer infection with a virus;
    • work on the provider's DNS server;
    • mistakes software on the site.

    Troubleshooting should begin by checking the simplest settings, and only if unsuccessful, carefully move on to more complex actions.

    Common DNS errors

    Consider the most common mistakes that are usually easy to fix on your own. As a rule, the correction does not take too long.

    DNS server not responding, unable to find DNS server address

    Probably the most common problem.

    This is what the error message looks like in the browser window

    When an error occurs as a result of trying to log in to a certain resource, and the rest work fine, most likely, problems arise on the site. Nothing can be fixed in this case. Be patient, maybe after a while everything will work normally.

    DNS errors can appear due to malfunctions in the router. And also the Internet provider may be to blame for their occurrence. Reboot or turn off the router for a while, perhaps this action will remove the error. There are no changes - try to connect the Internet cable to a PC or laptop directly, bypassing the router. If the action does not help, call your provider, the problem is probably on their side.

    When all devices are working fine, and the error occurs on one computer, it is most likely related to wrong work the device itself. Consideration of such an error is worthy of a separate publication.

    Windows cannot contact the device or resource

    Consider this option - the main applications continue to work, the Internet is connected, but the resource we need is not available, when accessing the site, a message appears on the screen: "Cannot find the DNS address of the server."

    Browser gives an error message

    To find out the causes of the error, run network diagnostics:


    Failure message when the system tries to connect to the DNS server

    This error can have different causes. Methods for solving the problem are selected accordingly:

    • incorrect operation of the anti-virus program - try temporarily disabling it or installing another one;
    • possibly failing DNS - Windows client- open the "Control Panel" section "Administrative Tools" tab "Services" and restart the DNS client service, turn off and restart the computer.

    If all of the above steps fail, try flushing the DNS cache. Press Win + R, in the window that appears, type "ipconfig / flushdns", start the process.

    The DNS cache is cleared by running the command "ipconfig /flushdns"

    After the above steps, everything should work fine.

    No access to DNS server

    Users often encounter a situation where all devices work fine, payment to the provider is listed, but access to world wide web missing. The reason for the error is incorrect Internet access settings. Everything can be fixed on your own.

    To resolve the error, do the following:

    1. In the "Start" menu, enter the "Control Panel", the item - "Administrative Tools", select the section - "Services".

      Select the Services section of the Administration section, Windows Control Panel

    2. Find the line "DNS client", there should be an inscription: "Working".

      When DNS is running, the DNSP client line always has the entry "Working"

    3. If the line is empty - move the mouse cursor, press the left button, call context menu by clicking Properties.
    4. Next, in the "Startup type" column, specify: "Automatically".

      On the tab, you must specify the startup type: "Automatic"

    Click the "Apply" and "OK" button.

    In a situation where the service is running, but there is no network access, the following actions should help:

    1. Log in to the control panel, there open the tab: "Network and Sharing Center".

      Open the Network and Sharing Center tab in the Windows Control Panel window

    2. In the "Change adapter settings" section, open the network connection context menu.

      Select "Change adapter settings" under "Network and Sharing Center"

    3. In the tab that appears, click on the "Properties" line.

      On the Connectivity tab local network", select "Properties"

    4. In a new tab, select the line "Internet Protocol 4 (TCP / IP 4)", click "Properties" again.

      Select "Internet Protocol 4 (TCP/IP 4)", click "Properties"

    5. In the next window that pops up, check the box "Use the following DNS server addresses".

      Set the server IP address manually

    6. In the line "Preferred DNS - server" type "8. 8. 8. 8".
    7. The line "Alternative DNS - server" must be filled in like this "8. 8. 4. 4".
    8. Press OK.

    If everything is done correctly, and positive result no, there is a strong possibility Windows errors. Try to restore the system to the last point when everything worked correctly. To do this, go to the Start menu, Control Panel, Recovery. Select a restore point, run the procedure, restart your computer.

    If the browser continues to give an error, the following actions are possible as an option to solve the problem:


    Such manipulations will help to identify an application that interferes with the normal loading of sites.

    Another reason for the error can be outdated network adapter drivers. Find its model. On the manufacturer's website, download new programs, install.

    If none of the above helped, then your computer is attacked by a virus, do the following:

    1. Download the Dr. Web CureIt or another with similar functionality.
    2. Run a full computer scan.
    3. Delete infected files.

    It is worth noting another mistake. Sometimes when you try to access the Internet, you can see the inscription: "Unable to resolve the DNS address of the server." Most often, the error is associated with repair work on DNS service provider of network access services. Test your internet connection by connecting another computer or laptop to it. If the error appears on all devices, contact the provider. In the case when the error is specific to one device, your actions are similar to fixing the "no access to the DNS server" error. Your system appears to be sending incorrect queries to the DNS server.

    Software bugs

    These include DNS failures caused by server software errors and individual sites.

    A temporary DNS error has occurred

    This message is caused DNS problems in Exchange 2013. Microsoft Exchange Server - software employee for messaging and collaboration. It's not entirely clear what "Temporary Server Error. Please try again later. PRX 3. At the end - there are also PRX 1, PRX 3, PRX 7. Unfortunately, there is no documentation.
    Known different ways problem solving. If your computer has a built-in LAN card, and additionally installed external, disable the one that is not used. To do this, you need to do the following:

    • start the PC or reboot if the computer is turned on and press the F12 or Del key when starting the BIOS;
    • the F1, F10 and other keys are used to enter the settings - if you don’t know which one to choose, read the text “Press ... to enter Setup”, where the desired combination will be written;

    Be careful, if you do not have confidence in your actions, do not experiment with the computer's BIOS, it is better to invite a specialist.

    When there is only one network card or disabling the second one did not help to remove the error, try these steps:


    Failed to resolve the DNS name of the domain controller

    A specific error rarely encountered by ordinary PC users. Typical for systems included in domain Windows networks managed by Active Directory. AD represents a set of processes and services that allows you to centrally manage the infrastructure of the local network. All computers on the network are combined into a common domain. The error occurs when trying to introduce a new server to the domain. The system displays the message "failed to resolve DNS - domain controller name."
    Try to take the following actions:


    Failed to load the page because the site was not found in dns

    The error mainly refers to the work of webmasters. When registering a new domain, DNS servers do not know its address. Until information about it appears on DNS servers, the site, mail, and other elements will not work. The DNS server registered for the domain acts as a “herald”, thanks to which the site address will become known to other servers. First, the domain information appears on the hosting DNS. If you are the owner of the site, and when you try to open it, the error “the address for the domain of this web site was not found on the dns server” is displayed, contact the administration of your hosting.

    A similar error can occur when transferring a domain to another hosting. In this case, the domain name of the site is the same, but the IP address changes. To solve the problem, you need to contact the administration of your hosting.

    Other Common Mistakes

    In addition to those already discussed, there may be other problems associated with the DNS server.

    Table: Common DNS Errors and How to Fix Them

    Event IDError messagePossible Errors and Corrective Action
    408 The DNS server cannot open a socket for the IP address. Make sure this is one of the server's valid computer addresses.If the IP address is valid, check if another device or program is trying to use the DNS service port (53).
    413 The DNS server will query other DNS servers on a non-default port (TCP port 53).This issue occurs on computers with multiple network adapters(when the DNS server is configured to use only a subset of the available IP addresses). In addition, it may be that remote DNS server responses try to use a port that is not configured to be used. local server DNS, which causes problems in zone data replication across WAN connections (through firewalls). To ensure that the configured port is used for all connections, change the configuration of the IP interfaces so that one of the following conditions is true:
    All IP addresses are used.
    Only one of the IP addresses is used.
    414 The server computer does not have a primary DNS suffix configured.For example, the server name is dns 1 instead of dns1.company.net. This configuration may result in incorrect or failed accesses. To fix this issue, join the DNS server to a domain, or provide a fully qualified DNS name that is appropriate for the workgroup.
    708 The DNS server did not find any primary or secondary zones. The server starts in cache-only mode and is not authoritative for any of the zones.If building only a caching DNS server was the main goal, then nothing needs to be done. V otherwise this message implies that zones need to be configured on the server.
    3150 The DNS server has written a new version of the "zonename" zone to the file filename. new version can be viewed by clicking on the tab.This event occurs when the DNS server is configured to act as the root server. If this is an undesirable result, you must remove the root zone (.) to prevent such messages from appearing.
    6527 The zone 'zonename' has expired before a successful zone transfer or update from the primary server that is the origin of the zone. The zone has been disabled.Secondary DNS server lost network connection with the primary server, so replication is not possible.
    Solve the network problem.
    On the secondary server, delete and re-create the zone with the correct IP address for the same or a new primary server.
    The primary server has an incorrect zone configuration in the SOA record. Fix it with one of the suggested actions.
    Make sure the Refresh Intervals value is less than the Expires After value.
    Decrease the Retry Interval value.
    Increase the Expires After value.
    Add the secondary server to the Notify List.

    At first glance, the problems listed in the article seem complex and almost unsolvable. But by carefully understanding the topic, everything can be corrected on its own. This will take patience and time. But the main thing you need is desire.
