My Server 2003r2 console screen has disappeared and can not be accessed. This is a working live server and it is NOT a hardware problem. When I sit in front of the server and log in locally as a domain admin, the desktop background comes up and nothing else. No menu, no taskbar, no icons, nothing when I push the Windows key, nothing when right clicking anywhere on the desktop. The mouse pointer moves normally. The only other normal thing is CTL-ALT-DEL will bring up the normal choices and I can log off, etc. Task Manager looks fine to me and shows console session 0. When I RDP from any machine, everything works normally and I am the only connection not disconnected.
I am pretty sure this started after I tried to do a remote software install. A box poped up from the software maker saying that it could only be installed from console 0 and giving some instructions. From the existing RDP session, I can type mstsc /v:myservername /console and get a new logon. That logon gets me the console 0 session and right back to the same problem as sitting in front of the server. No new software has been installed. I may not have understood the instructions and used the /admin switch the first time I ran mstsc.
How can I get the console operation back to being normal from in front of the server?
