Lack of DNS server what to do. The DNS server is not responding. What to do? The simplest solutions and advice. Checking DNS Service Status

Sometimes users need to install and configure a DNS server on their own operating system Windows 7. It can be used for work purposes, to create your own website, or for any other reason. Windows 7 is a graphical operating system (unlike Linux), the interface of which is intuitive, and setting up a DNS server is not difficult even for a person who does not have special skills. Similarly, you can fix errors with your own hands when the DNS does not respond, is inaccessible, or is not detected.

What is a DNS server and why is it needed?

DNS is nothing more than Domain Name System. As the name suggests, it is a server that issues domain names to IP addresses on the Internet. All sites have their own IP, in other words, a set of numbers that allows a computer to reach Internet resources (for example, 192.168.11.231). But when you change providers, the address changes, so how can users find out where their web portal is now located? This is why you need a DNS server; it gives human-readable names instead of IP and allows you to reach the desired address without knowing the set of numbers.

So, one day you decided that you need a domain name for mail, a personal website or an FTP server. You will need to install and configure a DNS server so that your host can be found without having to remember a complex set of numbers.

Where to find and how to enable DNS on Windows 7

The user on whose behalf all the following operations will be performed must have computer administrator rights.

In the Start menu, the first thing you will need to do is go to Control Panel.
If the control panel has an abbreviated view, then in the “Network and Internet” section, pay attention to “View network status and tasks”. If by default all Control Panel items are displayed in a single list, use Network and Sharing Center shared access».
In the “View active networks” section, find the connection through which you have access to the Internet (the one after “Connection”) and click on it.
A new window will open in front of you, displaying all the settings for the selected connection. Click the Properties button.
Among the marked components that are used by the connection, find “Internet Protocol Version 4 (TCP/IPv4)” or “Internet Protocol Version 6 (TCP/IPv6)” and click on the “Properties” button.
Activate the “Use the following DNS server addresses” item and enter the address of your server in the text field and an additional one if the first one is inactive.
After that, don’t forget to click “Ok” to save your changes.

When there is a need to change

Usually everyone uses their ISP's DNS server, but it doesn't always provide good speed downloads. In addition, such mechanisms often cannot cope with the load and “fall”, thereby limiting your access to worldwide network. Such free services like Yandex.DNS or Google Public DNS will help you get around this problem.

These are two largest companies who can afford high-quality equipment and cope even with heavy loads. Their servers are located in different parts of our country and the world. Thanks to this, as well as smart distribution of requests, the signal arrives at the nearest available server and pages on the Internet load several times faster than those of the provider. In addition, such services have many other settings: filtering, parental control, built-in antivirus and custom blacklist.

Due to the introduction of new laws in Russian Federation Providers are required to block access to some sites. Many people already know ways to bypass this limitation, and one of them is a DNS server. The law did not affect companies providing DNS connection services, which means that they have another advantage over providers.

How to set up or change

At one stage, you entered the server address and an alternative one. This is necessary because domain names from all over the world cannot be stored in one place. When a computer searches the DNS for the requested name, it searches several servers in the order that you can specify in the “DNS server addresses in order of use” text box. There may be not only two sets of numbers entered initially, but also several additional ones.

DNS suffixes are needed to form internal networks and subdomain names (for example, subdomain.domain.com). If you only need the server to connect to the Internet, then you can skip this setting and leave it as default. If you use, for example, internal working network, enter the suffixes of its subdomains in the appropriate field.

The enabled setting “Register the address of this connection in DNS” means that your computer will be registered on the server with its address and device name specified in the settings. You can find out the name of your device in the “Control Panel” in the “System” item. When the “Use connection DNS suffix when registering in DNS” option is enabled, an additional suffix will be added to the name of your computer on the network.

In what cases DNS may not respond and what to do

DNS service is disabled

It's possible that DNS on your device simply isn't working. You need to check the system services settings, to do this:

In the Start menu, find Control Panel.
Select System and Security.
In the next window, click on “Administration”.
A list of all available programs will open in front of you, select “Services”.
Find “DNS Client” and double-click on it.
Pay attention to the “Startup type” - this item should be set to “Automatic”.
After changing, do not forget to save by clicking “Ok”.

DNS server problem

If all the necessary services are enabled, and the DNS server still does not respond, it means that it is faulty. In this case, it is recommended to change it. To do this, you need to follow the same steps as when connecting the server, but instead of the old address, enter a new one.

What is a DHCP server and how is it different from DNS

While setting up your DNS server, you have often come across the acronym DHCP. What is it and what is it for?

DHCP stands for Dynamic Host Configuration Protocol. This network protocol, which automatically gives computers on the network the necessary IP addresses and other settings. For example, a network administrator can specify a range in which hosts should be located. This significantly speeds up setting up a large computer network and allows you to avoid many mistakes.

Unlike DNS, this protocol works exclusively with IP addresses and their settings. Together, these services represent a very powerful service and make the job of system administrators much easier.

A DNS server is needed to store domain names of various IP addresses on the Internet. Its use has many advantages: faster loading, flexible settings, bypassing resource blocking. Set it up in the operating room Windows system 7 is not difficult at all. And almost any connection problem can be solved by turning on the service or changing the server.

The DNS server does not respond - a common problem that occurs for many users. We will teach you how to get rid of this problem in no time. accessible ways– you will find them in our review! Bookmark it so you can useful tips were always at hand.

Reasons for the error

What does “DNS server is not responding” mean? This message often appears after diagnosing networks. Difficulties are also indicated by an icon in the form exclamation point appears on the taskbar.

It is necessary to highlight the reasons why the DNS server does not respond:

Error on the part of the service provider;
The computer settings have failed;
The problem lies with the router.

Malfunctions in the DNS, which is responsible for redirecting the IP address to the domain, are a very common problem. But you can get rid of it!

The “DNS server is not responding” error should not scare you - after all, there is a whole range of measures that will help solve the detected problems. We recommend that you first take a few simple steps - often they will help you figure out what to do if the DNS server does not respond.

If the Internet is connected through a router via cable or using WiFi, you should turn off the power to the equipment for one or two minutes and then turn it back on;
Try restarting your computer or laptop in a standard way through the start menu;
Check if the Internet works on other devices - on a tablet or smartphone;
You can try connecting the Internet cable to the PC directly.

As you can see, even if the DNS server does not respond, there is a solution! If simple ways did not help, we move on to complex manipulations. Don't be afraid, every user can handle it.

Client verification

The Internet does not work, the DNS server does not respond, what should I do? There is no need to wonder – it’s time to act. It is worth checking whether the service is enabled. To do this you need to follow a few simple steps:

Use the keyboard shortcut Win + R pressed simultaneously;
The Run window will appear, into which you need to enter the command services.msc;
Then click on the “OK” button;

In the list that appears, find the line labeled “DNS client”;
Right-click and select “Properties”;
Open the "General" tab and go to the "Startup type" section;
Select a value from the list "Automatically";
Click on the “Run” button and then on the “OK” icon.

If the service has been disabled, this method should help - we recommend restarting your computer. We figured out how to fix the error DNS server does not respond by turning on the service - let's discuss other options for solving the problem.

Clearing cache

If the DNS server does not respond on Windows, you can clear the cached data.

On Windows 7|8

First, let's look at the algorithm for 7/8 versions of the operating system:

Run command line on behalf of the administrator;
To do this, click on the “Start” button;
Select the “All programs” section;
Go to the line “Standard”;
Right click and select option "On behalf of administrator" on the inscription "Command line";

Enter several commands in turn;
Reboot your device.

Here are the commands you need:

ipconfig /flushdns;

ipconfig /registerdns;

ipconfig /renew;

ipconfig /release;

On Windows 10

Now let's see how to solve the problem on Windows 10:

Click on the “Start” button;
Go to the “Options” icon;

Choose a section "Network and Internet";

Go to the “Status” tab;
Find the line “Network reset”;

Click on the icon "Reset Now" and confirm the action.

That's all, we managed to clear the cache. If the device or resource DNS server does not respond, let's play with the settings.

Changing settings in connection properties

Are you experiencing DNS server not responding on Windows 10, 8 or 7? It doesn’t matter - you can “kill” the error with a few simple steps.

Click on the connection button on the taskbar with the right mouse button;
Choose a section "Network and Internet Settings";

Open the “Wi-Fi” or “Ethernet” block;
Go to line "Network and Sharing Center";

A menu will appear on the left side of the screen - select "Change adapter settings";

Right-click on the desired connection and select the line “Properties”;

In the “Network” tab, find the line "IP version 4 (TCP/IPv4)";
Select it and again click on the “Properties” icon, it is located just below;

In the “General” tab, find the line “Use the following DNS server addresses”;
In field "Preferred" enter the value 8.8.8.8;
In field "Alternative" specify the value 8.8.4.4. ;
Click “OK” and reboot the device.

As a rule, these are the steps that help figure out if the DNS server does not respond to Windows 7, 8, 10. Let's consider alternative options?

Router settings

This is a fairly rare case, but it is worth considering all possibilities.

Open any browser;
Enter the IP address indicated on back side equipment;

Enter your password and login to log in to the control panel;
Enter the “Internet” or “WAN” section;
Certain values are specified in the connection settings - compare them with the data in the provider agreement;
If the settings do not match, make the necessary changes and save them.

Another simple option on how to fix “DNS server is not responding” is managing your firewall and antivirus. Often these applications conflict with other utilities and users face difficulties.

Disable antivirus temporarily;
Or update your antivirus version;
Temporarily disable the firewall.

It’s also worth contacting your provider. If none of the above methods help, do not rule out technical difficulties on the side of the service provider:

Call support;
State the contract number;
Voice your mistakes and wait for a response from a specialist.

Now you know what “DNS server is not responding” means and you can deal with the error yourself. It’s not that complicated and shouldn’t scare you – you’re armed with the right tools to deal with technical problems!

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. 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 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 comfortable and correct redirection of requests to a domain from a specific IP address.

Often the DNS server does not respond in Windows 7/10 when connecting to the network via a modem and without using a 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 take personal interest and make changes to the modem settings, which lead to a loss of connection and an 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;

Checking the correctness of entering addresses in the settings. To check the literacy and correct filling of the DNS address, you need to go to the properties tab “Connections by local network", there you need to find "Internet Protocol v4" and check the specified address. The information that must be indicated in this field must be in the contractual connection documents. You can also find out the server address from your provider by contacting him by phone or other means;

Updating drivers for the network card. The problem can be solved by changing the provider and in some other situations;

Setting up antivirus and firewall. Modern programs that are designed to protect data and information on a PC from viruses and fraudulent activities can block access to the network. It is necessary to carefully review the settings of such programs.

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 power off 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	You should call the 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 right-click on it 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: ipconfig /flushdns ipconfig /registerdns ipconfig /release ipconfig /renew
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: Protocol (TCP/IPv6); Protocol (TCP/IPv4). 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 ones TP-link models the parameters are lost. 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 the basic settings on the TP-link router, 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.

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

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

What is DNS, how does it work?!

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

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

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

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

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

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

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

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

If the DNS server does not respond, change it!

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

8.8.8.8
8.8.4.4

Or from Yandex:

77.88.8.8
77.88.8.1

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

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

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

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

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

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

The antivirus has blocked DNS and it is not responding!

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

Therefore, when such a picture appears, for diagnostic purposes, it is worth trying for a short time disable Firewall antivirus, as well as a module Web Antivirus, if it is present in your security system.

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

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

Windows DNS client does not work

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

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

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

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

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

When all else fails

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

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

The “DNS server is not responding” error may indicate both problems with your computer and more global problems.

Now we will list everything that a user can do in such a difficult situation.

Simple ways to solve the problem

Sometimes a problem that seems very complex can be solved quite simply.

Here's what you need to do from the very beginning:

Restart your computer. Finding the true cause of this error can be quite difficult. It is quite possible that some operating system parameters are preventing it from connecting to the Internet. Therefore, it is better to start it again.
Reboot your router. The same applies - some parameters go wrong from time to time. You can try to find them and configure them correctly, or you can simply start the system again. The second option is faster. Just unplug the router from the socket and turn it on after a minute.
If the Internet does not reach through the router, but directly through the cable, check its integrity. If possible, it is better to even go up to the roof of the house to see what is wrong with the wires - often, for example, hooligans cut them for some reason. If there is damage somewhere, it is better to replace or isolate this area.
If you do connect through a router, try connecting directly. This way you can understand what the real problem is. If the connection is restored when connecting directly, try using a different router. This will make it possible to make sure that the problem is really in the old router.
Just wait a while. It is quite possible that the provider is doing some work or for some other reason the connection is temporarily unavailable. Then you just need to wait a little.

Server settings

It happens that certain settings for connecting to the server, for example, its address, are lost. Therefore they need to be corrected.

This is done like this:

Click on the connection icon in the tray (bottom right) with the right mouse button. In the drop-down menu select " Network Control Center...».
In the window that opens, click " Change settings…» in the panel on the left.

On the connection you are using, right-click and select “Properties” from the drop-down menu.
In the window that opens, left-click once on the item “IP version 4 (TCP/IPv4)”. A little lower, click the “Properties” button.

To put it simply, there should not be any addresses in the next window. Check two boxes " Receive address automatically", click "OK", restart your computer and try connecting again.

If installation automatic receipt addresses did not help, try setting the Google server addresses - and 8.8.4.4.

This should be entered as “Preferred DNS Server” and “Alternate DNS Server” respectively.

Clearing cache

When connecting to DNS, a lot of different information is accumulated, in other words, a cache.

You should get rid of it, like any other type of cache.

The same applies to various temporary network parameters.

Fortunately, this can be done very simply - you only need to enter 4 commands:

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

They should be entered into the console, which is launched by entering cmd commands to the command execution window.

Let us remind you that it opens by pressing the “Win" and "R" buttons.

After entering each command, press "Enter" to execute it.

Driver Update

In some cases, updating drivers helps network card.This is done as follows:

In the "Start" menu, enter " Driver Manager" in the search bar. Run the found program.
Find the section " Network adapters" There may be several devices. It's best to follow these steps for each of them.
Right-click on the device and select " Update drivers».

In the update window, first select automatic search for drivers. If necessary files will be found, install them. And if all else fails, try finding drivers for the selected device on the Internet. To do this, simply enter a query like “ [Device name] drivers" Then click " Search for drivers on this computer" If the system cannot find them, specify the path to the files manually.

It is advisable to restart your computer after this. But the Internet can be restored even after a regular update.

Disabling utility programs

The computer may have certain programs installed that work with the Internet.

They can use certain ports, some completely block the connection to the Internet or filter or limit it in some way.

For example, many antiviruses have a parental control feature.

It allows you to “detect” in time and not open sites that contain inappropriate materials (pornography, violence, etc.).

Of course, to perform such a function, you must have access to the connection.

Another example is a firewall. It literally filters all materials that reach the user.

But in some cases such programs do not work correctly. For example, they can completely block the Internet, despite the fact that the user did not give them such a task.

Some settings may be lost.

Therefore, all programs that are somehow connected to the Internet should be temporarily disabled.

But it is important not to turn off all of them at once. In this case, you will not be able to find the culprit. It is better to disconnect them one by one and see if the connection is restored.

The antivirus usually turns off easily - right-click on its icon in the tray and select “Exit” or “Disable”. In the picture below this process shown for .

The same goes for many other Internet-related programs. They all involve creating a tray icon.

If this is not the case, go directly to the entire program and look for the shutdown button there.

As for the firewall (aka firewall), to turn it off, do this:

In the window that opens, click " Turn Windows Firewall on or off».

Place two checkboxes next to the items “ Disable Windows Firewall (not recommended)" Click "OK".

As you can see, there is nothing complicated about this.

System rollback

Most likely one of latest changes in the operating system resulted in a lack of connection.

Therefore, it is best to roll back the system to a state when everything was still good.

To complete this task, do this:

In the Start menu, enter the query “recovery”. You will be able to find the program " System Restore" Launch it.
In the first window, click "Next".

Next you will see the available restore points. Rely on the date when everything was fine with the connection. Click on the desired option and click "Next".
