AD sites/moving a DC

We are building a new Win2000 Domain Controller for a new remote site. [currently have only 1 site]

I understand that if we build the new DC here in St Louis, then move physically move the computer to the new site, we need to take a few extra steps to ensure that the DC knows it is in the new site.

We are doing the same with the workstations (XP based)–building them here, then shipping to remote location.

Any hints appreciated!
Thanks.
