If the deployment of FCS updates doesn't work through Software Updates SCCM . I want use SCCM packages for distribute FCS updates (Delta definitions), i not want include AM_BASE update (50 MB) due to bandwidth, what files i have to include in the package?

This is a tricky subject. If you allow FCS to get updates from WSUS on SCCM clients, then FCS does just that, it gets them from WSUS not from SCCM which means the SCCM DP's are not being used for content. This is a headache. Steve Bobosky wrote an article on deploying the updates from software distribution, you may find that handy. It's a two part blog here: http://systemcentertools.blogspot.com/2009/07/pretty-good-solution-for-deploying.html John Marcum | http://myitforum.com/cs2/blogs/jmarcum |

We are deploying definitions for Forefront by using this document http://technet.microsoft.com/en-us/library/dd185652.aspx it's a couple of years old, but seems to work OK. The only issue is reporting. You also have to check (under the SUP config synch settings page) one or the other of the radio buttons to send WSUS reports to see if they are reporting status back to the WSUS server. A word of caution...MS sends Forefront definitions out mulitple times during the day, so you'll be sending the package often.
