We currently have WSUS configured to auto approve defintion updates and a group policy to "Allow Automatic Updates immeadiate installation" WSUS is not co-located with SCCM but we do mange it with SCCM as a Software Update Point.
My question is, that whether or not I have the "Use Configuration Manager as the primary source for definition updates" checked or not in my policy it appears as if I am getting updates through WSUS.
What is the difference in checking that box and not checking that box?
