DNS Server Not Working

DNS server not working is a message Internet users often come across.


This makes one wonder what is DNS server and how to make it work. In some cases, users may get DNS error message or “DNS Server Not Responding”. What to do in such a case. We will help provide you with a simple solution that will help you get back online.

Troubleshooting DNS Server Not Responding


DNS stands for Domain Name Server. When you cannot connect to a DNS server, you get error messages. It is a very common problem and has a very simple solution. Let’s find the common reasons for the error messages received.

#1 There is a problem with the hosting system


When you open a website, you get a message “The site can’t be reached”. The website’s server DNS address is not to be found.

This can occur due to:

  • DNS server not responding. This is a temporary problem when the website is facing downtime issues.
  • DNS server not found. This happens when the link you enter has expired or the website you are trying to open has shut down.
  • DNS server unavailable. This message occurs when the website is completely closed down and the hosting company no longer provides hosting services to this particular website.

 

Solution to the Problem


When these messages occur, all you can do is wait for the website backend to resolve the server issues. Once the site is up, you can access it easily.

#2 DNS server on your computer is having problems


At times, the DNS server is unavailable at your end. It can also happen that the DNS server on your compute is not working and has become corrupt.

Solution to the Problem


As the problem lies within your computer network, you need to take certain steps to rectify it.
Windows OS users need to:

  • Open the Network and Sharing Center
  • Click on the ‘Change Adapter Settings’.
  • You will now reach Local Area Connection icon. Right click on it and select Properties.
  • Now, a new window will open and you need to select Internet Protocol Version 4 (TCP/IPv4).
  • Again select Properties.
  • You can now change the DNS address by selecting “Use the following DNS Server addresses” option.
  • Enter 208.67.222.222 in the Preferred DNS server. Enter 208.67.220.220 in the Alternate DNS Server.
  • Select the box that says “Validate settings upon exit”.
  • Now, finish the process by clicking OK.

This is the most effective solution that will solve your “DNS server not working” or “DNS server not responding” problem.

  • End the process by clicking on “Apply Now to Apply Settings”.

You may need to restart your system to allow the changes to take place in a MAC device.

#3 Computer Antivirus and Firewall Protection


Many times antivirus or firewall on the computer can block the computer from accessing certain websites.

Solution to the Problem


You need to change the settings of your antivirus and firewall and then restart your system. Check again and you will be able to access the website.
