Name Not Resolved Error in Windows

Instead of emailing him the solution I have decided to write a post about it so everyone can be benefited from it. Follow the fixes given below to fix Err_Name_Not_Resolved error.

Fix 1 – Flush / Renew DNS

The first thing you should try doing is Flush and Renew DNS. You can simply do this using windows command prompt. Click on Start button then type in cmd in the search box. Right click on cmd.exe then click on ‘Run As Administrator’. Once the command prompt window appears, type in the following lines one after another and hit Enter after each line.

netsh winsock reset
ipconfig /flushdns
ipconfig /registerdns

Flushing / Renewing DNS

This will flush the DNS cache and register a new DNS which will solve the problems regarding un-responsive DNS servers.

Fix 2 – Change DNS Address

If the above method doesn’t solve the problem, then you have to manually assign DNS server addresses on your computer. There are tons of free DNS servers out there. In this tutorial we will use Google DNS addresses as they are one of the best out there. You can start by right clicking on the network icon from the task bar and then click on ‘Open Network and Sharing Center’.
