After the server has been up for a number of days we can no longer login with Remote desktop.
Initially after entering the logon/password an RDP window would open with all of teh video region black. After about 20 seconds an error dialog box would open: "Failed to reconnect to your remote session. Please try to connect again."
Repeated attempts to connect all fail.
I am able to mount the servers C: drive and view files.
I tries restarting any service that looked related to RDP.
I no longer get the black screen and the logon fails silently.
I compared the Event Log messages from a working system and a failing system.
The 1st divergence is the 36th event (out of 106 in the working case).
The error event is ID-227
'Failed to create Input devices in CUMRDPConnection::NotifySessionId ' at 1976 err=[0x80070102]
This error in Visual Studio "Error Lookup" translates to "The wait operation timed out."
In the working case the 36th event is ID=66 "The connection RDP_Tcp#27 was assigned to session 2."
A reboot always recovers, butt hat is not acceptable. I see that many others have posted similar problems with RDP.
Please advise.
