I have an outdated DNS entry on my Windows 7 PC, and can't seem to get rid of it.

  • I've run ipconfig /flushdns in an admin command line
  • The hosts file is empty except for localhost
  • I've restarted the PC

None of that has helped. I see the correct IP address using nslookup.

  • Can you add more detail, is this an external server or something on the local network? Is it a Windows machine?

Problem solved - the main and backup DNS servers had conflicting data, and for some reason nslookup used the main and everything else used the backup, reinserting the wrong entry into the cache every time.

  • Hey I'm having this problem too. nslookup is showing the correct answer but everything else is still using the wrong answer. How did you flush the backup?

  • @Pacerier: the backup DNS server had wong data, it just needed to be configured correctly.
