After a system state restore on a virtual server 2016 running Exchange 2016 the system login is not available. This looks like: (using Hyper V manager) the Server main screen that prompts for Ctrl + Alt + Delete shows but when the button is clicked to enter the key sequence it does not present but returns immediately back to the main screen requesting the Ctrl + Alt + Delete sequence. Using a Remote Desktop configured for the Server the password box appears, when credentials are entered the RDP acts like its going to load but fails.
Since the Hyper V manager Ctrl + Alt + Delete fails to produce a login screen it seems like something in the Windows structure that controls that is corrupted?
All other server functions can be managed by connecting to the server through that MMC Snap-in and Exchange is running and working such as Computer Management.
Any Assistance would be appreciated.
