I am logging in to a windows 7 enterprise machine on a corporate network. Occasionally when I rdp in to the machine the screen is entirely blank. This is specific to the operator id. If I log in with another user id the screen appears normally. I have noticed that if I don't quit the remote session and try to log in from another machine (bumping first connection) the screen will usually go black. I have also noticed that network issues can initiate the problem, but this is rare. I have seen the rdp - reconnecting icon flash and than the screen go black. Any ideas on what can be causing this problem?
One other note: processor utilization spikes to about 50% (1 core) when the screen goes black.
