Have a look at the Infrastructure Planning and Design Guide for SCCM 2007 and see if this helps you with your planning. http://technet.microsoft.com/en-us/library/cc196387.aspx Thanks, TomKind Regards, Tom Ziegler http://www.sccmguy.com | Twitter @Tom_Ziegler

I would add secondary sites in those sites. Futhermore (with the information you provided us) I would add a central site and multple primary sites. Number of primary sites depends on the number of secondary sites to support and the number of locations.Kent Agerlund | My blogs: http://blog.coretech.dk/author/kea/ and http://scug.dk/ | Twitter @Agerlund | Linkedin: /kentagerlund

Thanks for replymohamed

1. That should work 2. You can not change the SCCM Site Code. The only way to change the site code is to totally reinstalling SCCMKind Regards, Tom Ziegler http://www.sccmguy.com | Twitter @Tom_Ziegler

1- is that meanning it must be (manual/client push/gp /login script ,..) install sccm client per primary or can be done with old sccm ? 2- sccm secondary site will have same its primary site code or different ? mohamed

1. You can install manually, client push or gp. What do you mean by install with old sccm? if trying to install the sccm client from a system that is no longer, it will try to look for the old server, mp and site code and not report to the new server. 2. The Secondary site will have its own site code and it will report to the primary site code. Kind Regards, Tom Ziegler http://www.sccmguy.com | Twitter @Tom_Ziegler

· Hi Mohamed, Furthermore, clients are not assigned to a secondary site. And when you have a parent primary site with sitecode ABC, and a Secondary Site with sitecode DEF, client at a Secondary Site will still show the ABC code of the primary site.
