I have a site that is connected to my site with a Metro Ethernet link. However, their internal LAN addresses conflict with the servers in my DMZ. I've created a new subnet there and moved most of the machines to the new subnet. I am now trying to move their domain controller to the new subnet. They only have one domain controller. It is a WIN2K3 server and runs DHCP and DNS as well as their active directory. Is it just a matter of changing the IP address of the server, registering it in their DNS (which is the server itself), changing their DHCP scopes and getting the clients to renew their IP addresses?
