How to Flush Your Computer's DNS Cache

When a computer visits a website for the first time, it stores the website's DNS information in cache. The next time the computer visits a website, it looks in the cache to see if the website's information is present to use. This can cause problems if the website's DNS information has changed since the computer's last visit. Flushing the cache removes all the information stored in cache, forcing the computer to find the new DNS information for the website.

1) On your PC click 'Start' in the lower left screen and select 'Run'.

2) This will open a window where you will enter 'cmd'.

3) This will open a command prompt window.

4)Where you see the (>) symbol, type the following; ipconfig /flushdns and hit the enter key.

5) Once your DNS cache is clear you should see a 'Success' message.
