I've got a Windows 2003 network with WinXP machines running perfectly at one of my sites, Site A. I've now installed a domain controller at Site B. The replication is working perfectly. Both Servers are Global Catalogues, and I can ping the new server from everywhere.
If I try to connect to the server using RDP from Site A I can get it, but from Site B I cannot, even though it is on the same subnet. Also, a PC imaged and working at Site A, when moved to Site B says it can not find a machine account, although it is able to find a user account.
What is going on? How come I can't access a server on the same subnet, even when using the IP address?
