I'm trying to get rid of an old Windows 2000 Server that is the DC and DNS server. I added DC and DNS to an existing Windows 2003 Server and it looks like it replicated all the Active Directory data (I see users and machines listed) but when I unplug the old server and login to the network at a workstation I don't get access to the internet, when trying to use the new server as the DNS server, or to local network stuff. DHCP is handled by a SonicWall. I think I may have both DC and DNS server configuration problems. Which do I need to fix first?
