I installed updates and rebooted my DC in a remote site only to find out that terminal services was ended but the actual server did not reboot.
I ran shutdown -i from another machine and got the famous reply: 1115 A system shutdown is in progress.
I tried various switches to no avail. I then connected with SCCM to the console and saw that the Shutdown was stuck on “Notifying Services of the Shutdown”.
I then found a command line to use that reboots the machine in 60 seconds:
taskkill /s \\somepc /U administrator /P pass /im lsass.exe
Maybe not the best tool but when you in another country it is pretty difficult to just go and hard boot the server. Hope it helps.
