We are running Server 2012 and have 2 terminal servers (virtual) that we use RDP to access the desktop.
In the last week or so, whenever we try to log in, we can enter our credentials and then we get a black screen for about 1 minute then is knocks us off. It won't display the desktop. If we reboot, we can then access it for a few more times, then it does it again.
What do I need to check?
