pulling from WSUS instead of MS

[ccheath]

I searched the repo for 'wsus' and only found reference to the wsusscn2.cab file (which I don't think is really related to using WSUS instead of the MS source for updates...

Is there a way to choose the source for the updates?

You could try this?
Set-WUSettings -WUServer "wsusserver.domain.local" -AcceptTrustedPublisherCerts -DisableWindowsUpdateAccess -TargetGroupEnabled -UseWUServer
or
Set-WUSettings -TargetGroup "TargetGroup" -WUServer "wsusserver.domain.local" -AcceptTrustedPublisherCerts -DisableWindowsUpdateAccess -TargetGroupEnabled -UseWUServer

When I run Get-WUSettings it shows my WUServer information already (set by GPO).
So as long as I don't use the -MicrosoftUpdate switch it should be using my WSUS?
