It would be more helpful if you provided more info, such as do you just want to change the IP of the domain controller, or the whole network? Is DHCP running on this machine, how many users do you have, printers with IPs, any other resources that may be port remapped from your NAT/firewall, etc.

Is this SBS or non-SBS?

First, it is suggested to not put Exchange on a DC. The changes a DC makes vastly hits Exchange in the performance area, as well as may cause issues with the databases and transaction logs, because a DC disables write-behind cache on the machine, a non-reversible setting as long as it is a DC.

As for changing IPs:

Instruct everyone to shut down their machines on the Friday before the weekend that you plan the IP change.

Change the internal interface on your router/NAT/firewall first. Connect to it either using a web interface or telnet.

Then change IPs on your printers to the planned IP they will have. Either connect to them using a web browser, or simply change them on their console, depending on the printer manufacturer.

Then on the DC, assuming the DC is single homed (one NIC) and not two NICs (another issue with DCs if more than one NIC or IP), simply change the IP on it, then run:
ipconfig /registerdns
net stop netlogon
net start netlogon

Then assuming DHCP, you will need to recreate the scope, and the scope options (DNS, WINS, gateway, etc.)

I hope that helps.
