I have two Windows Server 2003 Standard machines that are domain controllers, one in the main office and the other in a satellite office. They are set up for AD replication. I'm replacing the box in the main office with a new Windows Server 2008 Standard R2 machine. The DC in the satellite office will remain on Windows 2003. I found some good instructions here for replacing the main office machine (Q23582347) but haven't come across anything yet about what if anything I need to do to the Windows 2003 box that will stay in production in the satellite office. I need to make sure it remains healthy and I can still replicate AD.
