Join Now. We have a remote site with 30 Domain users, we have a Power Edge 2900 with 4 gb Memory running Windows Server 2003 Operating System. We are planning to add a new Domain Controller and keep the existing one as a secondary domain controller. Users are also using the domain controller as a file share server.
The same rules apply; only one PDC may exist on a domain, but multiple replication servers may still be used. 1  The PDC emulator master acts in place of the PDC if there are Windows NT 4.0 domain controllers (BDCs) remaining within the domain, acting as a source for them to replicate from.
