  There are no "primary domain controllers" in Active Directory. It's multimaster. There is one "primary domain controller emulator" in each domain that-- erm-- emulates an NT 4.0 primary domain controller-- but that's it.

    Plus the other FSMO roles... and some things only work with the PDCe... and some DCs can be RODCs...
