I am designing SCCM 2007 in Single Forest (Empty Domain) with Multi-domain with the help of Adaptiva OneSite which eliminates need of a lot of SCCM requirements for such a design.
Customer wants a Primary site in a child domain.
Schema for this domain has been extended.
All domains in the forest have two way trust.
1) Do I need to extend schema at the top level (Empty domain) as well?
or this will work because of the two-way trusts
2) What effect will this have on the MP traffic?
