I have a SBS2003 server as the only DC. I want to add a 2012 server and eventually transfer DC and FSMO to the new server. Server 2012 says it cannot dcpromo because it fails verification of replica, and tells me I have to raise Domain Functional Level (DFL) to 2003.
On the sbs server, the gui shows the DFL is 2003. DSQUERY returns 2,0 which is supposed to be 2003,nonmixed.
But the new server still will not dcpromo.
Anybody dealt with this?
