If nslookup returns old data…

Today I made some record changes at the nameserver. But for a brief moment I was confused. The
nslookup > set d2 > host won‘t show up my adjustments as expected.

Then the DNS cache came to my mind …
In order to ensure that the nslookup shows current data, clean your DNS cache. To do so, simply run cmd:

ipconfig /flushdns 

You could as well stop the DNS cache service to reset the DNS resolver cache:

net stop dnscache
net start dnscache

Additionally clean the dns resolver cache on the server as well. That will force the server to re-read its tables instead of handing out cached info.

Cheers
