I see this pop up alot but not my exact situation. I have a 2012 R2 server that suddenly went black over night. Yes RDP or console or safe mode I can login but then goes black.
task manager works and I can run commands (including reboot) explorer.exe does not work, however I can browse from the launch new task box. I launched server manager and I'm doing a system state restore but anyone have a better clue how this happened?
