We have a new branch office with a 10MB WAN link b/w our main office and this new branch office. I have placed one Windows 2003 DC in the branch office. I plan on making this server a GC, DNS, DHCP, etc. This branch office is also on a different subnet than our main office. What configurations would be best in Site and Services? Currently, I only have one site with 4 DCs listed (3 in main office and 1 in branch office). Under subnets the only subnet listed is the main office subnet. Should I just add the branch office subnet here and that's it? Or do I need to add another site and set it up that way? I don't want to make this complicated but just want to be sure I minimize the traffic on the WAN the best I can. Any help is appreciated!
