Dns Problems On One Dc

[ryantremblay]

We just upgraded our two Windows Server 2003 domain controllers to Server 2008 R2. We upgraded our second DC first (BDC which doesn't exist in 2000-2008) so I ran the adprep commands on our first DC (that has all of the roles like BDC, Operations, etc) once the upgrade was completed we did the the first DC. Everything installed ok then we had problems with people going onto the net, we noticed if they had an incorrect Second DNS Server (the BDC) they couldn't get out, once we added it worked. The main DC will not go out on the internet on it's own using it's DNS Server, also when I do a recursive test it fails, on the other server it works fine. The main server is in our DNS root hints and when I try to resolve the name I get an error "server IP is not Authoritative for the required zone". Any help on this would be appreciated. Also transferred all of the domain roles back to the first server.

Just wanted to let everyone know that the problem is resolved. I think it was an issue with another DC at a remote location that we have not upgraded, and only replicates to other DC's in the evening becase it is on a slow connection. Thanks
