We currently have one site, one forest, and two AD servers (the master is 2000 and the second AD server is 2003). Currently we are setting up a remote site at a data center that is connected to the main office via a BOVPN. We want to put an Active Directory server at the remote site so user can login into the application that we have running on the servers at the data center. I've got a 2003 server ready to go and I've setup a new site in ADSS. I've also setup a new subnet using the IP subnet that the two servers are working with at the data center. My question is should I join the new server to the domain at the main office then take it to the data center or do everything from there. The new server is going to need to be setup as a DNS server as well correct? Are there any special settings I need to consider for the DNS setup?
