Hello
I need some serious assistance wrt WSUS.
I have WSUS 3.0 SP2 running on Server 2008 SP2.
My Sync to Microsoft Update fails (also fails via Server Configuration Setup).
I have tried to re-install.
Re-install IIS, WSUS and ReportViewer. And start with new Database. Then the sync works but no clients can report to WSUS.
I then installed WSUS-KB2734608 and then the clients start reporting in, but the sync fails.
The error I get is: Webexception: The underlying connection was closed. Could not establish trust relationship for the SSL/TLS secure channel. Then something about: Remote certificate is invalid according to the validation procedure.
But I have never used SSL on Wsus.
I have checked permissions on server. Proxy settings. Reboots. Services restarts. Wsusutil.exe resets.
I also see download failed on all updates. I only approved a few to test and see if they download. But to no avail.
I think the whole WSUS is broken at the moment and I don't know what else to troubleshoot and what to do next to get the Sync to microsoft working and getting the updates to download.
Please assist. Any tip or advice would be greatly appreciated.
Please ask if anything above is unclear or confusing.
Kind Regards
