The DNS server (Domain Name System - Domain Name System) is an essential and key part of everything related to the network since its job is to convert domain names into IP addresses and vice versa, this allows when we open a browser we simply enter the name of the website but not its IP address, this is the fundamental task of the DNS but additionally it can carry out other actions such as:

 

DNS Tasks
  • Caching function thanks to which the performance is improved and the load on the DNS servers is reduced and to achieve this the local DNS cache is used.
  • It has redirection functions with which it is possible to redirect domain names to other names or linked IP addresses.
  • Load balancing on DNS servers with which it is possible to distribute domain name requests using several web servers, lightening the load between several servers and not just one.
  • Mail management features and more.

 

 

 

When the DNS does not respond, we can see that access to the sites is simply impossible or errors may occur during browsing. If you are presenting this type of DNS error, TechnoWikis brings a group of options with which it will be possible to provide a comprehensive solution to this problem..

1 Fix DNS Server is not responding using the Troubleshooter


The troubleshooter is a tool integrated into Windows 10/11 with which it automatically seeks to carry out an analysis of the parameter to correct if there are errors or launch suggestions if the system cannot do it.

 

Step 1

To make use of this option in the search engine, we enter the word "solve" and click on "Solve other problems":

Step 2

The following window will be displayed: There we will click on the "Run" button located in the "Networks and Internet" section and a new window updated to the already traditional Troubleshooter will open:

Step 3

In the event that the network has faults, options will be launched to be executed, otherwise we will see the message that the network has no faults. We can see that the utility gives us some options to use to correct this DNS problem, we can click on each one of them to see their use or close the wizard.

2 Fix DNS server not responding using another browser


Many times we use a special browser but it may have internal failures in its processes or in any of its configurations on the remote server.

 

In this case the solution is simply to open another browser and validate that the website opens normally:

3 Fix DNS server not responding by clearing DNS cache


As we mentioned before, the DNS cache is used to reduce the load on these DNS servers since when accessing the same site or domain, the query will not be made globally in the DNS but will be made in the locally stored cache, but an excess of this cache can cause errors that result in DNS not responding.

 

Step 1

To release this cache we open the CMD console or the terminal as administrator:

 

image

 

Step 2

We accept system permissions:

 

image

 

Step 3

In the console we execute the command:
 ipconfig /flushdns

4 Fix DNS server not responding by disabling VPN


VPN networks (Virtual Private Network) are a part of security that allow us to protect our information and data that is transmitted using secure tunnels, but this type of configuration can have a direct impact with the DNS by blocking its normal activities, there the ideal is to deactivate the VPN.

 

Step 1

For this we will go to the route:

 

  • Start
  • Setting
  • network and internet
  • VPN

 

 

 

image

 

Step 2

When accessing there we will see the following:

 

image

 

Step 3

We deactivate the switches available there and we must confirm if there is any active VPN network, if so, we disable it:

5 Fix DNS server not responding by updating drivers


The network drivers allow the communication between the system, the physical equipment and the network to be correct in terms of speed, compatibility and other criteria, so it is essential to have the updated drivers.

 

Step 1

For this we are going to open the Device Manager:

 

image

 

Step 2

In the "Network adapters" section we are going to right-click on the current driver and then click on the "Update driver" option:

 

image

 

Step 3

We will see the following options. We click on "Search drivers automatically"

 

image

 

Step 4

and wait for the process to finish. To complete this process we are going to click on "Search for updated drivers in Windows Update"

 

image

 

step 5

and Windows Update will open:

 

image

 

step 6

There we are going to click on "Search for updates" to check if there is any for the network adapter:

6 Fix DNS server not responding by changing the DNS


The default DNS is managed by our internet provider or ISP and if their servers collapse our DNS will join the collapse and we will not be able to access any site, in this case we can resort to public DNS that are stable, secure and with great capacity of support.

 

Step 1

In the search engine we enter "network" and click on "View network connections":

 

image

 

Step 2

In the displayed window we right click on the current network adapter and then select the "Properties" option:

 

image

 

Step 3

In the pop-up window we locate the line "Enable Internet protocol version 4":

 

image

 

Step 4

We click on "Properties" to see the following:

 

image

 

step 5

In this new window we will activate the "Use the following DNS server addresses" box and enter the desired IP address:

 

image

 

step 6

There we can use options like. We apply the changes and we can check if the DNS is already working correctly.
 Google: 8.8.8.8 and 8.8.4.4 Cloudflare: 1.1.1.1 and 1.0.0.1 OpenDNS: 208.67.222.222 and 208.67.220.220 Quad9: 9.9.9.9 and 149.112.112.112 

7 Solve DNS server does not respond by disabling antivirus


On some occasions the antivirus can detect some packets and network protocols as threats and blocks their use, input or output, affecting access to websites, to rule out that this is the cause we can temporarily disable the antivirus.

 

Step 1

To do this, we enter the word "security" in the Start search engine and click on "Windows Security":

 

image

 

Step 2

There we will go to the "Antivirus and threat protection" section and then click on "Manage settings":

 

image

 

Step 3

The following will open:

 

image

 

Step 4

We are going to deactivate the "Real-time protection" switch and we must accept the system permissions to confirm this process:

 

image

 

step 5

We see that the antivirus protection has been disabled:

8 Fix DNS server not responding by disabling IPv6

 

The IPv6 protocol is the new generation of IP address since IPv4 is limited due to the increasing number of devices that connect to the network, IPv6 makes use of 128-bit addresses which exponentially increases its ability to offer IP addresses but is a protocol that is still in the process of being official on each computer so this can cause us a conflict with the DNS that is associated with IPv4, the most practical thing is to disable it.

 

Step 1

In the search engine we enter "network" and click on "View network connections":

 

image

 

Step 2

We right click on the current network adapter and select the "Properties" option:

 

image

 

Step 3

Now we are going to select the line “Enable Internet protocol version 6”:

 

image

 

 

Step 4

We deactivate its box and apply the changes:

9 Fix DNS server not responding using Safe Mode


Safe Mode in Windows allows us to access using the minimum of drivers to perform various administrative tasks in the system and be able to work on the problem in a much more direct way.

 

Step 1

To make use of this mode we go to the route:
  • Start
  • Setting
  • System
  • Recovery

 

 

 

image

 

Step 2

We will see the following:
