After leaving a Windows 2012 Server running over the weekend, upon logging in the following Monday I was faced with a slow loadup followed by an error message popping into the center of the screen
Image Of Error
"Explorer.exe - System Warning"
"Unknown Hard Error"
Upon clicking OK the server loads up correctly except for the basic windows functions no longer work, the start menu does not load and the run command doesn't load any given command correctly from the task manager.
Everything else however seems to be working as expected, this error persists even after rebooting.
If anyone has encountered this issue or have any suggestions I will be more than willing to try them out, note that re-installing the operating system is a last resort for me in this scenario.
Thanks for any time given in the aid of this question.
