How to Flush Windows DNS cache

How to Flush Windows DNS cache

The following walk through will guide you through clearing your DNS Cache. Every time you venture onto the Internet DNS resolutions are being made and your computer stores many of them. Caching these resolutions can speeds up your web activities because your computer no longer has to ask another computer where something is located. Eventually there will come a time when a bad entry is stored. There are generally two ways to remove these entries. First is to allow 24 hours to past. During such time your computer will seek out and make the necessary DNS updates. Second would be to Flush Your DNS.

First Step to Flushing your DNS, is to open your Windows Command prompt

  1. WinXP: Start, Run and type cmd and press enter.
    Vista: Start and type the word Command in the Start Search field. Finally right click the command prompt icon and select the option to Run as Administrator.
  2. In the open prompt, type ipconfig /flushdns (without the quotes).
  3. You should receive a message of your success as confirmation when the cache is cleared.

Flushing the cache removes all the information stored within the cache, forcing the computer to find the new DNS information.
