WSUS 3.0 SP1 on Server 2008 SP2

[OutLawTorn]

Having issues Synchronizing Wsus 3.0 SP1 on a Server 2008 Sp2 machine. We've tried the obvious google, restarting, un/re-installing wsus, etc and the problem still occurs. Internet connection is working fine, SQL database is fine, WSUS website is fine.

 

Error log just has Windows Server Update Services event id 10022 which says "The last catalog synchronization attempt was unsuccessful" (tried all solutions from eventid.net with no success)

 

The Synchronization details just says "The error type is unknown" and the details link gives the following:

 

InvalidOperationException: There is an error in XML document (1, 458200). ---> System.IO.IOException: The decryption operation failed, see inner exception.

Is the server going through a proxy?

Direct connection to Internet on ADSL...

WSUS 3.0 SP1 should work fine on Server 2008. If you're not going through a proxy then it must be a firewall or something along these lines.

 

Has it ever worked properly or has it recently just stopped working?

[FN-GM]

Might be worth trying to disable Windows firewall in advanced options.

Can you post a more complete log file possibly?

It implies its routing to the net but the xml file is corrupt but if it is not proxied its hard to say why.
