non authoritative answer
When i do a nslookup command external the response i get back is non-authoritative answer. It does give name, address and aliases. When i do one internal it works fine. I have i forward lookup zone configured. Inside that lookup zone i have two naming servers. The SOA is pointing to my DNS server. I have a host record of my DNS server inside the forward lookup. I also have a forwarder configured for this DNS server. What have i configured wrong to get that sort of reply back from nslookup?

well, the way I understand it is this. When your local server cannot localy find the domain your looking for your forwards ( to your isp's dns ) gets the request and thats where your non authoritative answer comes from. When you do nslookup on a local pc you wouldn't see that because your dns knows where it is itself.

rsheppick wasn't correct on how nslookup works.

I would need to see the nslookup commands you used to tell you why you got a non-authoritative answer.

rsheppick wasn't correct on how nslookup works but he was correct about why you got your non-authoritative answer. You should specify your server like this example:

C:\>nslookup - ns1.mydomain.com

There's nothing wrong with the non-authoritative answer from your ISP's caching server.
