DNS server is not responding or is not available: solution

If the DNS does not respond, you can refresh the IP through a series of steps, disable the firewall, use other browsers or restart both the router and the PC to rule out that it is a direct Internet problem. By executing some of these steps, you can have the Internet back on your computer. If the problem persists, you should contact your Internet provider and raise the problem.

When the Internet connection is slow or gives the message “ DNS server is not responding ”, it is due to a failure of the recognition of the IP address and the server. In fact, the acronym DNS stands for ” Domain Name System “, therefore, a name is assigned to each Internet address, which is sent to the DNS server from the router. If the server does not connect, the web page will not be accessible. However, you have different options to solve this problem from your Windows computer.

Using the Windows troubleshooter

When the website is offline, it usually indicates the problem. If it doesn’t, you can go directly to ” Network Connection Status ” to search for a troubleshooter. This option indicates the failure and the possible solution that you can apply to the system. If you want to use this method, you just have to follow these steps:

Note: Some steps may vary slightly depending on the Operating System you have.

  1. Search for ” Settings ” on your computer.

Restart the router and PC

When the computer is overworked, the Internet servers may crash and be at a heavy level or slower than normal. That is why it is suggested to shut down and let the computer rest or, failing that, restart it.

Likewise, it is also recommended to restart the router and, for this, you only have to press the on / off button. You can also disconnect the power source and wait a minute to reconnect it. If the non-response message persists, it is necessary to opt for other alternatives.

  3. Choose ” Internet Protocol Version 4 (TCP / IPv4)” and click ” Properties.”
  4. Check the option of ” Use the following DNS server addresses ” and in ” Preferred DNS server ” write ” 8.8.8.8 “, and in ” Alternative DNS server ” enter ” 8.8.4.4 “. The latter is optional, just in case you have problems with the Alternative DNS. Then choose ” OK “.
  5. If you do not have Internet Protocol version 4, but rather ” Internet Protocol version 6 (TCP / IPv6) “, select this option and press ” Properties “.
  6. Press ” Use the following DNS server addresses ” and in ” Preferred DNS Server ” enter ” 2001: 4860: 4860 :: 8888 “, and in ” Alternate DNS Server ” type ” 2001: 4860: 4860 :: 8844 “. To finish, click ” OK “.

Modifying the command line

  4. Once you know it, enter this command ” netsh interface ip add dns name =” Ethernet “addr = 8.8.8.8 index = 1 “, press ” Enter ” and write ” netsh interface ip add dns name =” Ethernet “addr = 8.8. 4.4 index = 2 “followed by” Enter “. Replace ” Ethernet ” with the name of your interface.

With PowerShell

PowerShell is a cmd-like interface. In it you can write instruction commands, it is used by those who have experience in systems administration. The difference is that you must also enter the DNS server address manually and, for this, you only have to look at the following steps:

  1. In the Windows search, type ” PowerShell ” and right-click to choose the option ” Run as administrator.”
  2. PowerShell will ask for permission to make changes to the system. Choose ” Yes.”
  3. Enter “ Get-NetAdapter | select ifDesc, ifAlias, ifIndex, MediaType | fl “.
  4. Look at the name in ” ifAlias “. In this case it is ” Ethernet “. Now, if you have an Internet connection via network cable, you must enter the following command ” Set-DnsClientServerAddress -InterfaceAlias” Ethernet “-ServerAddresses” 8.8.8.8 “,” 8.8.4.4 “ ” and press “ Enter ”. (In “Ethernet” put the name of your network).
    Otherwise, if you are connected to a Wi-Fi or wireless network, type “ Set-DnsClientServerAddress -InterfaceAlias ​​Wi-Fi -ServerAddresses” 8.8.8.8 “,” 8.8.4.4 “ ”.

Use other browsers

If there is suspicion that the browser has connection failures, it is best to resort to other browsers that are not commonly used to rule out this failure. If you frequently use Google Chrome, try using Mozilla Firefox or Opera, or vice versa. If this was the error, it is advisable to uninstall and reinstall the faulty browser and obtain the most up-to-date version of it.

Disabling the Firewall

Firewalls are programs that restrict or block access to certain unauthorized pages. This in order to protect the computer from any malicious virus. However, this could be one of the reasons why the DNS server is not responding. In view of this, you just have to enter the control panel on your computer and disable the antivirus or firewall. After deactivating it, try to enter a web page.

As you have observed, you have different methods and options to solve the problem of ” DNS Server not responding “. If you have tried all the steps that have been explained and you still cannot access any page on the web, it is advisable to go to your provider or Internet company and request solutions to the virtual connection problem.
