The DNS server is unavailable, what should I do? Why the DNS server is unavailable: how to solve the problem. Possible problems and ways to solve them
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 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 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 settings and parameters, which helps to solve the problem quickly and effectively;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 to the problem 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 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:
|
You can enter the addresses provided by Google, which, in the opinion of the search engine itself, 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:
Checking settings;
It is necessary to re-enter the settings according to the instructions included with the router.
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 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.
If you have opened a website and, instead of the usual page content, you see error 105, which says “cannot convert the server’s DNS address,” it means that some kind of unexpected/planned system failure occurred on the side of the provider or the site owner.
The problem may also arise for you. We will look into the situation.
Often this happens after installing a program or after uninstalling antivirus software.
Preliminary measures
To avoid searching in vain for a non-existent problem on your computer, take a series of preventive actions that will show you what needs to be done.
First, check whether “cannot resolve server dns address” appears when logging into one resource or all of them.
If one site is to blame, it means that the provider has some problems or the owners of the resource are changing the equipment settings.
In this case, you can try clearing the DNS cache via the command line.
Go to Start, search for “run”, and then type the CMD command (in capital letters).
As suitable software, you can use any modern antivirus that is updated to the latest version. Or use one of these options:
- Bitdefender;
- Kaspersky;
- Panda.
These programs have the highest chance that after cleaning, all damaged system parameters will be returned to their original values.
In other words, the DNS problem will be resolved automatically without your intervention.
Some cases may require more complex interventions, but in the vast majority of cases, this simple set of techniques that were described in the article will help you regain access to the full content of Internet pages.
Important! In some cases, if the DNS server on your PC was registered manually, you will need to call the provider that provides the Internet access service. You can also consult him regarding interruptions in the global network.
If your “favorite” site is not working, and you see the message “ERR_NAME_NOT_RESOLVED”, then use the same Internet to find out exactly why the required resource is in a state of technical work.
In most cases, the information you are looking for can be obtained on social networks, forums and websites dedicated to covering such problems.
WHAT TO DO IF You can’t find the DNS server address and the page won’t load
Cannot convert server DNS address: quick solution to the problem
This article will discuss the situation when, when connecting to the Internet, the system reports that the DNS server is not responding. Fixing this problem is quite simple; all you need to do is follow the recommendations from the article.

The DNS server does not respond, what to do when the Internet connection begins to fail or is not connected to all sites, we will try to understand all the reasons for DNS server errors.
DNS (Domain Name System) is a domain server service that determines and matches site addresses (IP address) and domain name (for example, example.com). In the event of a failure or error, the DNS server may incorrectly determine requests from your device and, as a result, it will be impossible to connect to the site or the desired service. Many providers use DHPC - dynamic host configuration (automatically obtaining an IP address and other network parameters), so this error may be relevant when re-receiving network parameters, but as a result of a network, device or resource error, the DNS server does not respond and the necessary parameters are not assigned.
The main solutions to the problem when the DNS server does not respond (is unavailable) Windows 7 and 10, how to fix it? Let's look into it in detail!
Service operation
You need to make sure that the service is running correctly and is not stopped or disabled. DNS client is one of the main network services for correct work with the network and the Internet.
Open the Run window and enter the command services.msc 
Or press Win+X and select Computer Management (if Windows 7, then find the corresponding search item or open the Administrative Tools option). 
Find the DNS Client service and in the service properties make sure that the Type is set to “Automatic” and the status is “Running”.
In the registry, the following branch is responsible for starting the service:
HKLM\SYSTEM\CurrentControlSet\Services\Dnscache 
The Start value must be equal to – 2 (Automatic start type).
Changing connection settings
Open Windows Settings – Network and Internet – Adapter settings (or Win+R - ncpa.cpl), then open the properties of your connection. 
Open the properties of IP version 4 (TCP/IPv4) and set the DNS server to receive an automatic address or you can set public records of Google servers:
Updating network settings
Open a command prompt window as Administrator (Win+X). 
In the open window, enter the following commands:
Network reset
Open Windows Settings (+ ) – Network and Internet – Status and select Reset Networks, after executing all the commands, you need to restart the PC. 
Resetting the router
Well, as a last resort, try rebooting your router so that the settings of the router itself are reset, because on some devices you can set DNS addresses in the settings of the router itself. This is why it is often impossible to contact a device or resource.
The recommendations described in this article should help you solve the problem of what to do if the DNS server does not respond in Windows 10 and 7, but if the computer settings are configured correctly but the DNS server does not respond, which means there are several other reasons that may prevent the network from working correctly :
- Problem from the provider
- Problem with the site
- Network adapter driver problem
Have a great day!
The problem of permanent unavailability of DNS servers (English Domain Name System), unfortunately, continues to persist in the Belarusian segment of the World Wide Web. The DNS technology itself is necessary for the correct interaction of the computer browser and Internet resources with a specific domain name and zone.
Example: our website has a domain name
hpc and domain zone.by On the Internet, the resource is accessible by IP address (the address may change dynamically) 178.172.148.88
In order for the computer browser to easily find our site, there is a DNS service that, when asked for the name https://site/, issues a machine-readable address 178.172.148.88.
Modems are configured in such a way that they automatically receive DNS from the provider's servers. It happens that servers (or ADSL modems themselves) do not work entirely correctly or are very slow ().
When running troubleshooting, the following message appears:
A problem has been detected. The DNS server is not responding.
The situation looks like this.
In the system tray (notification area near the clock): a network icon with an exclamation mark. At the same time, there is money on the provider’s balance sheet; The computer (laptop) is working fine. This problem also occurs on the popular HUAWEI HG532e ADSL modem. Sometimes a given device begins to work correctly only after it is restarted.
When running the ping command: only a blinking cursor is visible.
To resolve a DNS issue:
- check whether the DNS client service is running on the computer;
- We switch to public DNS from Google.
You can check the DNS client service this way:
On the computer, press WIN+R (Windows icon on the keyboard). In the window that appears, type the command services.msc. A complete list of services will appear, find the DNS client. We check the startup type - Automatic, Status - running. OK. If that’s the case, let’s move on….no? Let's fix it.
Next we switch to public DNS from Google
This completes the manual setup of your computer to work with Google Public DNS. It is possible to make all the mentioned settings automatically, by pressing a couple of buttons using special utilities.
Automatic configuration of DNS servers
They will help you select the fastest and most stable DNS servers automatically (without using manual configuration).
This software can automatically test the speed of servers from a predefined list, and also apply all settings with the click of one button.
They can be used to select the fastest DNS servers based on your location; use as a filter for parental control and cutting off sites with viruses when surfing - the so-called Safe (Family) Home Internet.
