I have a WIndows 2003 Active Directory Server which is also configured to be a RRAS role. When I used my ISP DSL type connection directly to my Workstation, Running WIndows XP Professional SP2, I had no issues. However, When I began using the connectivity through the Windows 2003 AD / RRAS connection I discovered that all the Cisco VPN connections that use to work, still work, but RDP doesn’t.
I know that it is something configured incorrectly on the Windows 2003 server, but I don’t know where to began to look.
