It wasn’t until the recent Patch Tuesday, that I tried to check WSUS and came up with the following error. Had me baffled. The error wasn’t very descriptive and the event logs provided an error but nothing that got me any closer to resolving the issue.
After some research online, I worked out that one of the patches I had applied recently broke WSUS. KB3159706 was the culprit.
To fix the issue, uninstall KB3159706 (an update for Microsoft Windows). The update enables ESD decryption provision in WSUS in Windows Server 2012 and Windows Server 2012 R2.

And what do you know, working again.
