I've been running a Server 2012 Standard evaluation as a member server for a while - it has been a remote site AD server that connects to our existing Essentials domain ("PDC").
The server has been promoted so that our existing AD is replicating - all is working as expected.
My question: I have read that an evaluation cannot be converted to a standard retail if it is a DC. This server, although has been promoted to give the AD replication we desire, is not our DC... or is it technically a DC (because of the need to DCPROMO as part of adding the AD role) and I cannot convert it without a rebuild?
