I am in the process of building a small 3 server farm. Each machine is running Window Server 2008 R2.

As is normal, I am in the process of installing patch after patch to bring the machine up to snuff. Every time I restart the machine, or most every time, when I try to remote in to the machine I get the Log In window, but then almost immediately I get the message that my remote session was ended.

If I physically walk over to the machine and plug in a monitor and keyboard, I see nothing. If I leave the keyboard and monitor in and restart the machine by force, the computer reboots just fine. When windows starts, I get no error message about windows not starting or being shut off unexpectedly.

Once I log into the machine physically by the keyboard, I can then remote in to the machine at that point.

Very confused. This happens on all 3 machines, these machines have different hardware.
