Over the week, I have a problem on WSUS of my customers and struggled with that for awhile, I tried to install the KB2720211 and post-installation the WSUS crushed and didn’t work anymore, most likely it comes from the KB.
Got some error on event viewer like:
Error: Connection Error. An error occurred trying to connect to WSUS server.
The solution steps are:
- To change HKEY_LOCAL_MACHINE\Software\Microsoft\Update Services\Server\Setup\wYukonInstalled from 1 to 0
- Then install the update again
- reboot the server
- change HKEY_LOCAL_MACHINE\Software\Microsoft\Update Services\Server\Setup\wYukonInstalled from 0 to 1
- reboot the server install update AGAIN
- And the WSUS now works.
That was important for me sharing this solution with you guys.
Hope it was necessary.
