I have an SBS 2K server with ISA running; it is running TS in adminstration mode so that I can administer it remotely. Usually this all works fine, but occasionally (such as now), I am suddenly unable to make and RDP connection. I get the following:
Remote Desktop Disconnected. The client could not connect to the remote computer. Remote connections might not be enabled or the computer might be too busy to accept new connections. It is also possible that network problems are preventing your connection. Please try connecting again later. If the problem continues to occur, contact your administrator.
Now I am unable to make an RDP connection to this server from either the external or internal interface.
This was working fine until this morning when I installed the lastest security patches (from windowsupdate). When I rebooted, I was no longer able to RDP. I've installed these same patches on a different SBS 2K server that has ISA disabled and I have no problem with making connections. I am suspecting an ISA issue but am not sure what to do.
