I am bringing up two new Domain Controller (Server 2008R2) which will take over all FSMO roles from older 2003 DCs which will be retired. Our domain controllers are also DHCP, DNS, and WINS servers for our network. The retiring DC is the primary DNS and WINS server for this site. Obviously the new DC will have a new IP address since it needs to be brought up in the presence of the old one. I do not relish the thought of spending hours updating many statically-configured servers and devices to use a new primary DNS and WINS server address, so the thought I had was to add the old DC's IP address to the new DC after the old one has been shut down. So I'd end up with two IP addresses on the new DC (they are in the same subnet, not multi-homing). Is this supported on a DC? Any potential problems/gotchas?
I kept getting Event ID 8003 Browser error and event ID 4319
Thanks in advance for any suggestions.
