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
You can also purge the DNS server cache using the PowerShell.
Run this cmdlet from the dnsserver module:
Clear-DnsServerCacheAt the command prompt use:
Dnscmd /ClearCache
