I am trying to replace an old Win2003 DC server with a new one. I have installed Server 2003 on the new machine, connected it to the network, and I can see it fine. I've copied all data from the old server to the new one as well. I've also installed and configured DNS on the new server, exactly like it was configured on the old one. I have run ntdsutil to transfer all FSMO roles to the new server, and I ran DCPROMO on the old server to make it a member server (however, that process got interrupted...it timed out at one point).
My problem is that when I remove the old server from the network, I lose my internet connectivity from all desktops. I can still access the internet from the new server, but I can't access the internet from any desktops. I'm assuming that DNS is messed up somehow. What am I missing?????
