Please see the attachment, in Short: I am the network admin for Domain A, which is the Forest root for Domain A and Domain B. The domains are located in separate states connected by a MPLS Link. We have VPN setup on a Cisco ASA 5510 located at Domain A. We have setup users from Domain B to be able to connect to the VPN, which they successfully can; although, when they try to use Remote Desktop to connect to their PCs at Domain B the session fails to located their PCs. PCs located at Domain A can be successfully remoted into with no problem. Is this an issue with VPN, DNS/WINS, Remote Desktop, or something else I am missing?
