WSUS was working and then one day it stopped working. I have no clue as to why as there were no changes to my environment other than installing Microsoft updates, which are all up-to-date.
In a Hyper-V instance I’m running Windows Server 2012 R2 Standard. The workstations that I support are either Windows 10 or Windows 7 and I have about 200 machines. When I try to start the Management Console (3.0) this is the error message that is in the
clipboard
The WSUS administration console was unable to connect to the WSUS Server via the remote API.
Verify that the Update Services service, IIS and SQL are running on the server. If the problem persists, try restarting IIS, SQL, and the Update Services Service.
The WSUS administration console has encountered an unexpected error. This may be a transient error; try restarting the administration console. If this error persists,
Try removing the persisted preferences for the console by deleting the wsus file under
%appdata%\Microsoft\MMC\.

In the Server Management Console, I get the following error message
SERENITY 7053 Error Windows Server Update Services Application 6/24/2016 12:40:48 PM

So far I’ve rebooted, restarted Update Services service, IIS and SQL are running on the server and I’ve deleted %appdata%\Microsoft\MMC\wsus
Does anyone have any ideas how I can get this restarted?
Thanks, Sam
