Hi.
SCCM 2012 clients download scep definitions from http://download.windowsupdate.com/msdownload/update/software and not from any Site servers
I found that we have an GPO that overide Computer Configuration--Administrative Templates--Windows Components--Windows Update--Configure Automatic Update--dissable.
Found this on Technet forums.
. Run rsop.msc on your client to verify your WSUS group policy set up correctly
.Computer Configuration--Administrative Templates--Windows Components--Windows Update--Configure Automatic Update--enable this policy and set to 4-Auto
download and install
.Computer Configuration--Administrative Templates--Windows Components--Windows Update--Specify intranet Microsoft update service location--enable this
policy and set to http://WSUS_Server_IP:8530
What settings would we set if any, I think the SCCM 2012 client set this so you dont need an GPO setting.
