I have seen this issue too many times now, so I have to write this short blog about it!
Have you ever seen this error when trying to connect to a Remote Desktop enabled machine using MSTSC/Remote Desktop Client:
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.
Well, I’ve seen it so many times now, especially on ISA servers… Even after the RDP sessions have worked nicely, sometimes, for some reason, the RDP settings can be changed - or even “corrupted”. In most cases the above error has something to do with NIC (Network Interface Card) adapter binding to RDP.
If you are experiencing this issue go read the Microsoft KB article: “You can not establish a Remote Desktop session to a computer running one of the affected products”. You will find it here http://support.microsoft.com/kb/555382 - good luck!
