I have three subnets with two domains originally setup under NT4. The first domain on subnet 1 was converted to Windows 2000 with Active Directory and DNS using two domain controllers. DC 1 is the Global Catalog server and DC2 is the Infrastructure Update Master. Subnet 2 is at a remote site connected through a VPN router. This site has a DC (DC3) for servicing logon requests for their local users and simply supplies file services. This site belongs to the first domain.
Subnet 3 belongs to Domain #2. I upgraded the DC (DC4) in the second domain and made it a child domain of Domain 1.
Should i have seperate AD sites for my main location (domain 1), my remote site (domain 1) and domain 2? Right now I do (Site 1, Site 2 (remote site) Site 3 (second domain)). I setup the 3 subnets and assigned them to the corresponding AD sites?
Should the remote network be under Site 1 since it belongs to the same domain?
