I recently setup a new WSUS server (Server 2016 Core) and installed the console on my admin workstation. Everything was working fine but at some point something happened to the console and now it says "An unexpected error occurred". I'm given the options of unloading the WSUS span-in or copy the error message to the clipboard.
The process of unloading the snap-in never completes. Fortunately, the WSUS server itself still seems to work fine because I can use PowerShell to list needed updates and deny or approve them.
I've tried clearing the cached files from the console via File > Options... but that had no effect. I've also uninstalled the console and reinstalled it.
Any other ideas?
