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. DHCP is being handled by a SonicWall. I don't want to remove the old server from AD because I need to be able to fall back on it so people can still work. I think I may have both DC and DNS server configuration problems. Thanks in advance Mike

Thanks. We'll let you know when a new response is added.

Hi, did you transfer the DNS already? Remember that you need to transfer the DNS zones to the new server in order to let the users resolve addresses correctly.
Please refer to this article that explains the process

Also reconfigure your DHCP settings. You need to update the DNS server IP address in your DHCP server.

You also need to make the new server a global catalog, and probably transfer some of the FSMO roles to it as it is more powerful hardware.
