You can run the forest prep from anywhere as long as you have the appropriate rights. That said this should be done on the Schema Master. Once forestprep is done and replicated properly you can run domainprep in each child domain.

Hey everyone, long time reading here....I'm confused as I'm new to AD and doing my research for our conversion......so here is my question we are gong to have an MT root domain and a sub ( if that the correct term) domain where we are going to put exchange, let call the root domain " AD.sdccd" and the sub domain admin.What is the proper procedure for running Forest prep and Domain Prep? From all my reading I don't think I run forest prep on the sub domain but do run domain prep on the MT root and on the sub domain. Am I correct....john
