Amazon EC2 SErver RDP Lockout

We are having a problem trying to login to particular Amazon EC2 Server through RDP

For no apparent reason we will get this message
Even though no other users are logged in

And the only resolution is to reboot the server.

Any ideas?  Where could I see what is causing this?

Have the server's performance monitored using perfmon data collectors. It could well be, that it is running low on resources while in that error state.

CPU consistently at 5% and Memory at 15%

Like I said... baffling
How did you read that out? It needs to be read out automated, while in error state - not manually now.

Read it in the Task Manager
Pop up performance monitor

Did you understand what I am suggesting? Have perfmon setup to monitor the system and create logs. When in error state, simply look at the time when that happens and restart the machine, afterwards look at the logs to see what load was on the server at that point in time when you couldn't connect.
