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. Remember that the DNS lookup failure error message is mostly an issue with the web site’s network, everyone visiting this site is probably having the same problem as you. 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:
net stop “dns client” (including the quotation marks)
net start “dns client” (including the quotation marks)
netsh winsock reset
If you are using Mozilla Firefox but still get a DNS lookup failure error message, try the steps here and you can most of the time instantly solve the problem on your PC:
*Close your Mozilla Firefox completely or you can instantly get your computer directly into safe mode.
* Open your QuickTime
* Edit > Preferences > QuickTime Preferences
* Select “Browser Plug-in” from the drop-down list
*Click on the button that says “MIME Settings”
* Expand the “Miscellaneous” file format section by clicking on the “+” on the left
* Uncheck “Flash file”
* Click “Apply” and then “OK”
* Close your QuickTime
* Open Mozilla Firefox and check whether you are able to play flash correctly.
Fourthly, you should check and remove all PC viruses from the computer. We know that viruses, short for malicious software, are the small software designed to invade or destroy computer system. Normally all these will be done without your knowledge, for example, changing your homepage automatically; monitoring your web browsing; keeping popping up some error messages while you are surfing the net, making the computer to run slow, sealing your personal information, stopping you from installing applications on the PC, etc. When there are some malicious threats on the PC, you will fail to visit some pages by getting a DNS lookup failure error message. In order to retrieve your enjoyable computer experience and surf all pages as you like, you must figure out how to remove virus from your computer.
Last, a simple mistake in the Windows registry database can also cause the appearance of the DNS lookup problem. To fulfill any browsing activity, the system has to access and read thorough the registry database for its responding keys. However, when it fails to load any related entries and finish the browsing request, a DNS lookup failure error message will appear. For this concern, after all the above solutions you still need to run a professional registry cleaner to completely scan & fix all registry errors. With a registry clean system, you can enjoy the computer without problems all the time.
Well, no matter in using which web browser or visiting which webpage you receive the DNS lookup failure error message, just take it easy! The above steps will help you troubleshoot and solve the DNS lookup problem easily & allows you to surf the web properly all the time.
