How to setup automatic definition and security updates for Forefront Client Security through SCCM 2007 R2 and WSUS integration?

I've looked as far as I could on the web for information on how to setup automatic pushing and installation on definition and security updates for Forefront Client Security through the SCCM 2007 R2/WSUS integration model. I did find this link:

The clients I have (two, one is an XP pro SP3 machine, the other Windos 7 enterprise) will receive definition updates if configured through the SCCM console as a package, but they don't seem to update as the article above explains.

I am wondering what exactly what the best method is to auto aprrove and auto-push updates through SCCM 2007 and FCS. Should I see the SCCM software update icon AND the classic Yellow shield on the same computer? I have tried to perform a wuauclt.exe /detectnow to no avail.

In the registry for the XP and the Windows 7 machine the Windows Update registry keys for the WUServer and the WUStatusServer are both https://serverFQDN:8531. Also the clients show up in the WSUS console as reporting.
