The Domain Name Server (DNS) lookup process allows the computer to translate an easily remembered name, for example, “www.mydomain.com” to a numerical Internet Protocol (IP) address so that the computer’s networking software can communicate with the remote server properly. However, one problem that lots of PC users suffer right now is that they repeatedly receive a “DNS lookup failure” error message when trying to visit a page. Seriously, this seems to happen randomly, sometimes every half an hour or so. When this DNS lookup problem occurs, users fail to visit the desired pages correctly no matter which web browser they are using.

When a DNS lookup problem occurs, retry the URL several times a few minutes later to see whether you are able to visit it correctly. If you fail even though you have clicked the refresh/reload button, you can come back a little later.

If the web owner has noticed the problem and solved the issue, you can easily fix them a little later.

Secondly, make sure that you are connected to the Internet correctly. You can try the following steps to do if you are able to ping the IP such as Google Chrome IP address so as to solve the DNS lookup failed error: go to Start> in search box type cmd and click “Enter” to go> Right click cmd.exe in results above and choose Run as administrator> Type in the following commands one by one:

ipconfig /flushdns
net stop “dns client” (including the quotation marks)
