I am having a problem that I just can't sort out.
Windows server 2008 R2, This server has been working fine since 2013. Now all of a sudden when I am logged in remotely through RDP the RDP window will just freeze. If i try to reconnect, all I get is a black screen. If try to log in to the server while physically sitting in front of it, the log in window doesn't even come up. However the server is still running because I can copy files to its shared folders without issues when this happens. The only way I can get back into the machine is by rebooting.
Things I have tried: setting a timeout to 10 minutes on disconnected or idle RDP sessions.
Pressing ctrl + alt + end / esc when I get the black screen in RDP - doesn't work.
Disabled bitmap caching, and tried reconnecting with different resolution.
Checked for kb2830477 - not present.
I have also tried everything listed on this article, http://www.grishbi.com/2015/01/rdp-black-screen/
I am not sure what else to do. This server worked perfectly fine for years, now all of a sudden it's not working.
Any help would be greatly appreciated. Thanks.
