I am new to windows server. I just installed DNS on windows 2012 server. Here is how it appeared after installing

DNS Srver

Then i went to DNS manager. I created a new Forward Primary zone and reverse zone. Here is the screen shot

Forward Reverse Zones

Then i created the record (A, MX, CNAME). Here are the screen shots of each

SOA:

SOA

Name Server:

Name Server

A Record:

A Record

MX Record:

MX Record

CNAME:

CNAME

Reverse lookup Zone:

After all that when i do nslookup, then i get Default Server: Unknown. Why ? Why i am getting unknown server

nslookup

Why i am getting unknown ?

Thanks

  • Try `ipconfig /flushdns` or Restarting DNS Service, or [this post](http://www.randika.info/2013/01/how-to-fix-nslookup-default-server.html) – Brock Hensley Jan 22 '14 at 23:06

You did all correct, but you dont mentioned are you restart DNS service after that? After restart its working fine for me.

From the quick google research it seems to be a reverse PTR record issue. Try recreating the PTR record. Here is a NSLookup Unknown troubleshooting for a bit older version. This might work for Server 2012 as well.
