Our company is opening a second office about 30 miles away.  Both sites will be running Windows Server 2003 Standard+Active Directory.  The sites will be connected across a T1 tunnel.  How do we configure the domain/active directory so both server are in it?

    Use a different subnet at the other location.

    Then make sure you have a connection between the two offices.

    Then run DCPROMO on the server at the new office.  If you have the communications link setup properly, you'll be able to promote the remote DC into a Domain Controller.

    Then go to Active Directory Sites and Services and properly define your sites based on subnet.

    Both sites are running different internal IP schemes & subnets.  I've already setup the new server and installed Active Directory on it.  Have I gotten ahead of myself?

    Didn't see your post before I added my comment Leew.  So that I can learn/research this; in Microsoft Windows Server terminology I creating another site for my domain?  I a bit confused as this is the first time I've ventured out of the single office scenario.  Wasn't sure if I need anoither site or another tree.

    If you installed Active Directory on it but NOT as an additional domain controller in your existing domain, then yes, you have gotten ahead of yourself.  And while you COULD do it this way, it's not recommended and would cost you more in the long run with administrative costs, most likely.  If this is the case, uninstall AD (DCPROMO again) and then make it a member of the existing domain.  Then make sure you make the server an ADDITIONAL domain controller in your EXISTING domain.  

    You want to then define sites and services so that authentication of the clients is appropriately handled by the local domain controller.  You can also use this to utilize other Windows features such as DFS.
