Hi, got a 2008 r2 vm machine running on a 2008 std server w/hyper-v, it worked fine for years, but last week show this symptom black screen after boot up and when I press ctrl-alt-del shows a blank login screen. I could browse the files, can ping but can’t do rdc or use any app installed. Check all the forum and try all possible solution they said with negative results. Any suggestion or advice would be appreciated.
