How to Clear DNS Cache

Have you ever received an Error 404 on the internet?   If you experience DNS (Domain Name System) errors or Error 404, first check that your network connection is fine.   If so, you may need to flush the MS Windows' DNS cache.  To do this, follow the steps below:

 

  •  Go to start button and click RUN
  • Type  - command  - and hit the ENTER key
  • Type -   ipconfig /flushdns  -  and hit the ENTER key
  • Type -  exit -  and hit the ENTER key.

 

MS Windows XP and Vista automatically store DNS information about websites you have visited.   This loads those websites faster for future use.  Sometimes the DNS cache becomes corrupted or stores unusable data.  This causes errors (404 and DNS) and results in slow internet performance.   By following the above steps to delete the DNS cache, your Internet performance should be restored.
