I had a VM that whenever you tried to access the console or RDP into the server it just displayed a black screen as shown below
You could do a ctrl-alt-del and if you tabbed just right, and it was a big if, you could log into the server. Once logged in the server functioned correctly. Well I did the standard Google searches and checked out Microsoft’s knowledgebase but had no luck. I knew it must have something to do with the default profile as that is the one that is loaded before a user logs on.
Check out the full post The Black Screen of Death!!!!!! ; for the fix, thanks Tom!
