I'm trying to get rid of an old w2k server that is the DC and DNS server. I added DC and DNS to an existing w2k3 server and it looks like it replicated all the AD 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 trying to use the new server as the DNS server or to local network stuff. I think I may have both a DC and DNS server configuration problems.

Thanks in advance

Are you using the new DC as the DHCP server? If so you will need to do an ipconfig/release ipconfig/renew from the workstations so they get the new DNS information otherwise the workstations will be using the old DNS server for their lookups.

And did you demote the old server? You can't just unplug a DC from a network, AD has to know it is gone.

Thanks srhoades, no it's not a DHCP server, that function is done by a SonicWall. I just manually changed the DNS entry on the workstation. I'm afraid to tell AD to remove the old server because I need to be able to fall back on it so people can still work. I guess by unplugging it I was just emulating a real failure.
