We have a main office running in a Windows 2003 domain. We have a remote office that we plan to have connect to our main office with a site-to-site VPN connection (hardware-based). Currently the remote office users are in a workgroup. We plan on implementing NT Server 4.0 in the remote office as well. Essentially we would like to have the remote office users a part of our domain for easier management. What is the best to set this up using Windows Server 2003 and NT Server 4.0?
