Microsoft Remote Login
Well I had this problem now a couple of times in the last week or two.
Nothing specific running on the 2008 R2 server, I just disconnected and reconnected a couple of minutes later and I saw login was successful but then I got the black screen. Always had to restart the server remotely via shutdown /m \\server /r command.
Just found this topic here with the CTRL+ALT+END trick and will it try next time but I also use an Android RDP client which does not support such keyscombination.
I guess that this bug was caused by the patchday before the last one because it happened the first time for me two weeks ago and never had such a problem - also didnt change anything in the system or on the hardware.
I found only this in the logs (german)
