HOWTO: Flush Your DNS Cache on XP and Vista

| No TrackBacks
When making changes to your DNS records, you may need to flush your local DNS cache.  This can happen if you've submitted a DNS change, but the system you're using hasn't yet accepted the change.  Recently, I updated the DNS record for nick.kolich.com.  However, once I updated the record, my Vista machine didn't seem to recognize the change; even though all of my other boxes did.  In this case, I needed to flush my DNS cache.

On Vista, using an Administrator Command Prompt, run:

ipconfig /flushdns

On XP, run the same command, but you don't need to be an Administrator user:

ipconfig /flushdns

Yea.
