Just a quick one here. I am sure there are a number of other fixes around for this error, but a reminder here to check for the simple things.
Running Windows Update using WSUS on Windows Server 2008. Clicked the Check for Updates option and this error came up.
Check your proxy settings. If you use a proxy trhen ensure that you can access your configured WSUS server through the proxy, or disable the proxy. It seems that when you run the check manually it uses the system proxy settings (set in Internet Explorer) but when it is run automatically it does not. Seems strange behaviour – but that is how it appears to work.
If you are getting this error on a standalone PC not connected to an enterprise network, then it is highly likely that this will not apply to you.
