Today I have prepared an article for you that will help you solve one fairly common error that confuses even fairly advanced users: DNS server is not responding.
In this article, I will talk about the reasons for this error, as well as several ways to solve it. I will be waiting for confirmation from you in the comments what exactly helped you, as well as new options if anyone knows. Let's go!
1. What does “DNS server not responding” mean?
To proceed to troubleshooting, you need to understand what it means that the DNS server is not responding.
To understand the essence of the problem, you should know what a DNS server is. When accessing any virtual page on the network, the user gains access to a specific section of the remote server. This section contains and stores files that are converted by the browser used and presented to users in the form of a page with text, images and other information that is familiar to the visual perception of any user. Each server has an individual IP address, which is necessary to gain access. A DNS server is a functional means of conveniently and correctly redirecting requests to a domain from a specific IP address.
Often the DNS server does not respond in Windows 7/10 when connected to the network via a modem and without using network cable, as well as for users who use another wireless Internet connection method. In some cases an error may occur after installing an antivirus.
Important! Often, users personally show interest and make changes to the modem settings, which lead to loss of connection and the occurrence of unwanted error. Therefore, it is not recommended to edit working settings unnecessarily.
2. Dns server does not respond - how to fix it?
If the user observes an error, then there are four ways to eliminate it:
. Very often it is enough to reboot the modem to fix the error. During the reboot process, the device returns to its original state. initial settings and parameters, which helps to quickly and effectively solve the problem;To correct an error with a greater probability, it is necessary to consider specific situations in detail. This is what we will do below.
2.1. On Windows
There are several possible solutions problems listed in the table.
| Way | Procedure |
| It is recommended to disconnect the device from power or use the shutdown button, if provided in the configuration, and wait about 15 seconds. After the time has elapsed, you must turn on the device again. | |
| Using the Command Line | Should be called command line from the PC administrator. To do this, click on “Start”, then find and click on “Search programs and files” and write cmd. After these steps, a program shortcut will appear. You should click on it right click computer mouse and select "Run as administrator".Then you should type and execute certain commands, after entering each command you must press the enter key:
|
| Checking settings and options | You need to visit the control panel and find “Network and Sharing Center...”. This subsection contains information about the network. You should select the connection you are using, then right-click the computer mouse and select “Properties”. A new window will open for the user, in which you need to select in turn:
Then you need to click on “Properties”. You should check the boxes next to the items: obtain a DNS server and IP address automatically. When checking the settings, you must be very careful and take into account the information specified in the agreement with the provider, if any. This method only helps if there is no specific address specified by the provider. |
You can enter the addresses provided by Google, which, in your opinion, search engine, help speed up the loading of web pages: 8.8.8.8 or 8.8.4.4.
3. DNS server does not respond: TP-link router
Most modern users use TP-link routers and devices. Error DNS server is not responding can be eliminated in several ways:
Attention! Some, especially inexpensive TP-link models, have lost parameters. In this case, you should follow the setup instructions that come with the device and enter the data and DNS addresses specified in the contract and provided by the provider.
It is better to set TP-link on the router basic settings, unless otherwise specified in the agreement with the provider.
4. DNS server does not respond (Beeline or Rostelecom)
All of the listed methods for eliminating the error are designed to assume that it is the user who has the problem. But practice shows that in most cases, problems arise with the provider for a number of reasons, such as technical faults.
For this reason, if an error occurs, you should not rush, but wait a while: during this period, you can reboot the computer and router without touching any settings. If the situation has not changed, it is recommended to contact representatives of the provider company and tell about the current problem, providing the specialist with the data he requires: contract number, last name, IP address or other information. If the problem arose with the Internet connection service provider, he will report this and tell you the approximate time frame for eliminating the problem. This is especially true for Internet owners from the Rostelecom company (I myself am one of them, so I know what I’m talking about). Very useful numbers:
- 8 800 302 08 00 - Rostelecom technical support for individuals;
- 8 800 302 08 10 - Rostelecom technical support for legal entities.
If the problem did not arise with the provider, then a company specialist can, in some cases, help the user solve it by giving competent advice or recommendations.
Some PC users may encounter problems connecting to the Internet, and when troubleshooting, the system displays the message “The computer settings are configured correctly, but the device or resource (DNS server) is not responding.” In most cases, this error occurs on computers with installed Windows 7, but similar problems cannot be ruled out on other Windows operating systems. In this article I will tell you what the DNS server is not responsible for error, what are the reasons for its occurrence, and how to fix it.
As you know, a DNS server can be called either an application created to respond to requests via the DNS protocol, or the host on which this application is running.
The Domain Name System (DNS) itself is used to obtain an IP address from the host name (the user enters address bar browser is the alphabetic name of the site, and the DNS system translates this name into an IP address), for mail routing, and so on.
Causes of the “DNS server is not responding” error
So, what are the causes of the error “Your computer settings are configured correctly, but the device or resource (DNS server) is not responding”? I would note the following:
How to fix the error “The computer settings are configured correctly but the device or DNS resource is not responding”
So, if you are facing dysfunction device or resource (DNS server) is not responding, then do the following:
- Reboot the system. One of the most trivial solutions is often quite effective;
- Reboot your router. Unplug the power cord from the router, wait a minute, then plug the plug back in and turn on the device. The device memory will be cleared and it is possible that the problem DNS server is not responding will be resolved;
- Use automatic IP and DNS server address from Google. Click the "Start" button and type in the search bar ncpa.cpl and press enter. Find your Internet connection in the list of connections, right-click on it and select “Properties”.
In the list of components, find Internet Protocol version 4, double-click on it, and in the properties window that appears, activate the “Obtain an IP address automatically” option.
At the bottom, click on the option “Use the following DNS server addresses”, and write the address 8.8.8.8 in the first line, and 8.8.4.4 in the other. Check the “Confirm settings on exit” option and click “OK” at the bottom. Then try to reboot the system and go to the website you need on the network;
- Try updating your DNS settings. Open a command prompt as administrator (Click on “Start” and type in the search bar cmd, a program icon with the same name will appear at the top, right-click on it and select “Run as administrator”). Then enter the following commands one by one, remembering to press “Enter” after each of them:
ipconfig / flushdns
ipconfig / registerdns
ipconfig /release
ipconfig /renew
netsh winsock reset
Then reboot your system, and it is possible that the question “how to fix the error device or resource (DNS server) is not responding” will be resolved.
- Try setting the physical address as the network address in the network adapter settings. To do this, open the command prompt again with administrator rights as described above, type ipconfig /all in it and press enter .
The screen will display network parameters your system, pay attention to the “Physical Address”, consisting of letters and numbers (for example, 2A-3F-8E-B9-30-C9). Copy it onto your paper.
Now click on the “Start” button, in the search bar enter ncpa.cpl and press enter. Select an active Internet connection, right-click on it and select “Properties”.
After opening the properties window, click on “Customize” next to the name of your network card, in the window that opens, go to the “Advanced” tab, click on the “ Network addresses", activate the "value" option and there enter the physical address you wrote down earlier (without hyphens). Confirm the changes, then open your browser and try to access the desired site;
- Check your PC for virus programs (Dr. programs are suitable. Web CureIt!, Trojan Remover, Malware Anti-Malware and a number of others);
- Temporarily disable your firewall and antivirus, and then try to access the network, this may help with the question of how to fix the error: the device or resource (DNS server) is not responding;
- Check the operation of the DNS client service. Click on the "Start" button, enter in the search bar services.msc and press enter. In the services window that opens, find “DNS client”, double-click on it, and check that the startup type is set to “Automatic”. You can also try restarting this service.
Video solution
When analyzing the dysfunction “the computer settings are configured correctly, but the device or DNS resource is not responding,” you should first of all try to restart the router, and also update the DNS settings using the appropriate commands given above. If these tips do not help, try the entire range of solutions I gave above, they will help solve the described problem in the vast majority of cases.
It is impossible to imagine our existence without access to sources of information that the Internet provides. DNS servers are the connecting link of a network of computers. Unfortunately, sometimes errors occur in their work. In these cases, access to the Internet is limited or non-existent. Therefore, every user will benefit from basic knowledge on the topic.
What is a DNS server and why errors may occur
If you explain in simple words, you can call the DNS server address book Internet. Each computer connected to the network receives an IP address in the form of a digital 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 a DNS server works
Unfortunately, sometimes there are glitches in the chain. Errors occur. There can be quite a few reasons, let’s look at the most common ones:
- no internet connection;
- incorrect router or modem settings;
- incorrect firewall settings;
- The network card driver is critically outdated;
- computer infection with a virus;
- work on the provider's DNS server;
- errors software on the website.
Troubleshooting should begin by checking the simplest settings, and only if unsuccessful, proceed carefully to more complex actions.
Common DNS errors
Let's look at the most common errors that are usually easy to fix on your own. Typically the fix doesn't take too long.
The DNS server is not responding, the DNS server address cannot be found
Probably the most common problem.
This is what the error message looks like in the browser window
When an error appears as a result of an attempt to log in to a certain resource, and the others work fine, most likely problems arise on the site. There is no way to fix anything in this case. Be patient, maybe after a while everything will work as normal.
DNS errors may 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 clear the error. There are no changes - try connecting the Internet cable to your 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 normally, but the error occurs on one computer, most likely it is due to the malfunction of the device itself. Consideration of such an error is worthy of a separate publication.
Windows can't contact the device or resource
Let's consider this option - the main applications continue to work, the Internet is connected, but the resource we need is unavailable, when accessing the site, a message appears on the screen: “The DNS address of the server cannot be found.”
The browser displays 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 antivirus program- try to disable it temporarily or install another one;
- maybe the DNS is faulty - Windows client- open the “Control Panel” section “Administration”, the “Services” tab and restart the client DNS service, turn off and start the computer again.
If all of the above steps are unsuccessful, try resetting 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 completing the steps, everything should work fine.
No access to DNS server
Users often encounter a situation where all devices are working normally, payment has been made to the provider, but access to World Wide Web absent. The cause of the error is incorrect Internet access settings. Everything can be fixed on your own.
To resolve the error, do the following:
Click "Apply" and "OK".
In a situation where the service is running but there is no network access, the following actions should help:
If everything is done correctly, but there is no positive result, there is a high probability Windows errors. Try performing a system restore to the last point when everything was working 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 generate an error, the following actions are possible to solve the problem:
Such manipulations will help identify the application that interferes with the normal loading of sites.
Another cause of the error may be outdated network adapter drivers. Find its model. On the manufacturer's website, download new programs and install.
If none of the above helped, then your computer is attacked by a virus, do the following:
- Download the healing utility Dr. Web CureIt or another with similar functionality.
- Perform a full scan of your computer.
- Remove infected files.
There is one more error worth noting. Sometimes when you try to access the Internet, you can see the message: “Unable to resolve the DNS server address.” Most often, the error is associated with repair work on the DNS service that provides network access services. Check your Internet connection by connecting another computer or laptop to it. If the error appears on all devices, contact your provider. In the case where the error is specific to one device, your actions are similar to correcting the “no access to DNS server” error. Your system appears to be sending incorrect queries to the DNS server.
Software errors
These include DNS failures caused by software errors in servers and individual sites.
A temporary DNS error has occurred
This message is caused by DNS issues in Exchange 2013. Microsoft Exchange Server - software product messaging and collaboration tool. It is not entirely clear what “Temporary server error” means. Please try again later. PRX 3". At the end there is also PRX 1, PRX 3, PRX 7. Unfortunately, there is no documentation.
Known different ways solving the problem. If your computer has a built-in network card and an additional external one installed, disable the one that is not in use. To do this you need to do the following:
- start the PC or reboot if the computer is turned on and when starting the BIOS, press the F12 or Del key;
- To enter the settings, use the F1, F10 and other keys - if you don’t know which one to choose, read the text “Press... to enter Setup”, where the desired combination will be written;
- in the parameters, open the section with the word Integrated, where you will need the line On Board LAN or something similar;
- change the status of the line to Disabled to deactivate it;
- Don't forget to use the Save and Exit button to save your changes.
BIOS panel, through which changes are made to the hardware configuration
Be careful, if you do not have confidence in your actions, do not experiment with the computer BIOS, it is better to invite a specialist.
When there is only one network card or disabling the second one does not help clear the error, try the following actions:
Failed to resolve DNS domain controller name
A specific error that is rarely encountered by ordinary PC users. Typical for systems included in domain Windows network under control Active Directory. AD represents a set of processes and services that allows you to centrally manage the local network infrastructure. All computers on the network are united 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 the following:
Couldn't load the page because the site wasn't found in DNS
The error mainly relates to the work of webmasters. When registering a new domain, DNS servers do not know its address. Until information about it appears on the DNS servers, the website, 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, domain information appears on the hosting DNS. If you are the owner of a website, and when you try to open it, the error “on dns server If the address for the domain of this website was not found,” contact your hosting administration.
A similar error may 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 your hosting administration.
Other common mistakes
In addition to those already discussed, other problems may arise related to the DNS server.
Table: common DNS errors and how to resolve them
| Event ID | Error message | Possible errors and corrective action |
| 408 | The DNS server cannot open a socket for the IP address. Make sure this is one of the valid server computer addresses. | If the IP address is valid, check to see if another device or program is trying to use the DNS service port (53). |
| 413 | The DNS server will send queries to other DNS servers on a port other than the default (TCP port 53). | This issue occurs on computers with multiple network adapters (when the DNS server is configured to use only a subset of available addresses IP). In addition, it may turn out that the answers remote servers DNS is trying to use a port that is not configured to be used local server DNS, which causes problems in replicating zone data 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 calls. To fix this problem, connect your DNS server to your domain or provide full name DNS that will be suitable 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 creating only a caching DNS server was the main goal, then nothing needs to be done. Otherwise, this message implies that you need to configure zones on the server. |
| 3150 | The DNS server wrote the new version of the zone "zonename" to the file filename. New version can be viewed by going to the tab. | This event occurs when the DNS server is configured to act as a root server. If this is not the desired result, you will need to remove the root zone (.) to prevent these messages from appearing. |
| 6527 | The zone "zonename" expired before the zone was successfully transferred or updated from the primary server that is the source of the zone. The zone has been disabled. | Secondary DNS server lost network connection with the primary server, so replication cannot be performed. Solve the network problem. On the secondary server, delete and recreate the zone by specifying correct address IP for the same or new main server. The primary server has an incorrect zone configuration in the SOA record. Fix this by using one of the suggested actions. Make sure that 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 having carefully understood the topic, everything can be corrected on your own. This will require patience and time. But the main thing you need is desire.
Sometimes it becomes very annoying that you cannot use the Internet due to a completely banal error “DNS server is not responding.” In the vast majority of cases, when it is not possible to find the DNS address of the server, the problem can be solved in a matter of minutes. In this article we will look in detail at all the ways to solve this problem.
DNS server is a utility that redirects the Internet user to a website. The fact is that any Internet page is stored on a server that has its own IP address. To give a user access to a site, a DNS server connects the user's computer to the server. In other words, the DNS server is the connecting link between the user and the site.
Errors “DNS server is not responding” or “DNS address cannot be found”
Often the browser complains that it cannot find the DNS address of the server. This message occurs most often among desktop users using a connection without cables (3G/LTE modem or Wi-Fi router). However, it can also appear in those who use wired Internet. This error means that the unit from which the user accesses the site cannot find a DNS address that will redirect him to the server with the page he is looking for.
What to do if the DNS server is not responding or is unavailable
Before you try to decide this problem, you need to first find out why it arose:
- Because of incorrect settings modem or router;
- Due to incorrect settings operating system(the site is blocked by a virus or firewall, or the Windows DNS client has failed);
- Due to an outdated network card driver.
To do this, you need to go to the network control panel located in the lower right corner of the task bar. It has a monitor icon, next to which there is an Enternet cable. Click on it with the left button of the manipulator. Next, right-click on the field where it says “Connected”, then go to “Properties”. Click on the “Network” tab and go to the “Properties” item, after clicking “Internet Protocol Version 4”. In the DNS addresses tab, try selecting the “Load DNS server automatically” option. If this does not help, then enter the address (preferred and alternative) yourself. It is written in the contractual connection certificates. You can also find out the DNS address from your ISP by calling them.
Advice: the correct DNS address can be registered not only in Windows settings, but also in the control panel of the router itself. If you are using software utilities from TP-LINK, then use the parameter quick setup(Quick Setup).
Often a virus carelessly downloaded by a user blocks access to other sites. To check the system for existing malware, you should scan it with an antivirus. In this case, it is better to perform scanning with a program that does not require installation on the desktop and is located on a Live-CD or Live-flash drive (Live media is storage space independent of the main system). For such purposes, we can recommend Dr. Web CureIt! Portable anti-malware programs are good because, being placed on a Live-CD or Live-flash drive, they cannot be infected with viruses.
Setting up a firewall
There is a possibility that access to the site has been blocked native Windows Farewall or firewall (another name for firewall) that comes with your antivirus. The firewall blocks access to sites that it considers malicious. If you know that the blocked page is truly safe, you can temporarily disable the firewall or reset its settings to the initial settings (then the list of blocked pages will be reset to zero). How to turn off Microsoft's firewall? Click Control Panel->Windows and Security->Windows Firewall. In the left panel there will be an item “Enable and shutting down windows Firewall". Click it, then turn all the toggle switches to “Turn off Windows Firewall.” Save these settings.
Advice: Windows firewall– key. By turning it off, you will disable other firewalls.
Updating network card drivers
Often the desktop refuses to connect to the Internet due to outdated network card drivers. To check their status, use the Driver Booster utility. This application will help you find not only drivers for network controllers and install them, but also update the functionality of other components.
Advice: you can update the network card drivers and standard Windows utilities. Go to “Devices and Printers”, then double-click the left mouse button on the icon of your desktop. In the “Equipment” tab, find the components marked as “ Network adapters” and go to their “Properties”. There, click on “Driver” and select “Update”.
This method involves resetting the desktop and router settings. The sequence of actions is as follows: you need to disconnect the router from the 220V network and leave it unconnected for 5 minutes. Next, you need to restart your computer and plug the router back into the outlet.
Advice: Before turning off the router, you should go to its settings menu and reset the default settings.
This problem can be resolved in two ways. The first - the least painful - register the DNS address not through the Panel Windows management, but through the router menu. The second is to perform a system restore. Go to the Control Panel, then – “System and Security” – “Restore a previously saved desktop state”. After a few minutes, when the utility collects all the registered backup points, you need to select one of them. The date of its creation is written next to each point. Select the one where the DNS client was functioning normally and confirm the system reset.
How to find out the dns address of a server
The correct DNS address is specified in the agreement on connecting the desktop to the Network. It was compiled by the provider, so there is no possibility of error. If you do not have access to the certificate, you can call the provider or contact him via technical service support and ask him to provide the exact DNS address again.
Where can I configure the DNS server address in Windows?
It can be configured through Windows utilities (path: network icon in the taskbar - “Settings” - “Network” - “Internet Protocol v4” - “Properties” - tab with DNS addresses) or through the control panel of your router or modem.
Programs for setting up a DNS server
If the DNS server is unavailable, then the DNS Jumper utility will help fix this problem. Its advantage is that it is portable and does not require installation. In the “DNS Server Selection” tab, you can select a DNS address manually or let the utility itself select it. In this case, DNS Jumper will select the most stable and fastest server on at the moment, and the “DNS server does not respond to windows” problem will be removed. You can also download the DOT VPN add-on to your browser. This extension allows you to select not only the address, but also the country from which the user will log in. That is, you can physically be in Germany, but access the site as a resident of the Netherlands. A very useful extension, since some pages are blocked by state governments, and DOT VPN allows you to bypass this ban. “ Setting up a VPN» in the Opera browser. It is turned on like this: Settings->Security->VPN (switch the toggle switch to “Enable” and select “Optimal location”).

Sometimes users encounter a problem when the server is not responding. What to do in such a situation to get it back to work as quickly as possible? First, you should try to find out the cause of the failure, and then try to eliminate it.
Reasons why the server is not responding
Often the server does not respond due to a network problem. To eliminate it, you should make sure that it has a working and valid network connection. First of all, you need to check the serviceability of the corresponding client equipment, that is, cables and network cards. If this is all right, then you should make sure that it can contact routers or other computers that are on the same network using the ping command.
If the DNS server can be reached through normal network checks, but is not responding to client DNS requests, you should check to see if the DNS server is running and can respond to client requests and listen for connections. To do this you need to use the nslookup command.
It happens that the DNS server is configured to provide limited service to a certain number of configured IP addresses. And the IP address that was originally used when checking the server responses was not included in this number. In this case, you should repeat the server check by specifying a different IP address, which is among the restricted interfaces. If the DNS server responded to the request from this address, then you should add the missing IP address.
Sometimes, the reason that the server has stopped responding may be that it is using a non-standard service port. In this case, you should make sure that the DNS server is not using a non-standard configuration. If this is the case, you should investigate whether the intermediate proxy or firewall is specifically configured to block traffic through known service ports that are used for DNS. If not, then you should add a packet filter to these settings, then traffic will be allowed to standard DNS ports. In addition, you should check the DNS server event log to see if any critical 414 events have occurred, which will help indicate why the server is not responding. Now you know what to do if the server stops responding and you can fix the problem yourself. If you did not find the cause of the failure in this article, then you can ask a question about this on the official Microsoft website.
