Can't promote Windows 2012 Server in 2008 domain
Posted on 2014-10-23
I just joined a new Windows 2012 Server to a 2008 Domain.
I want to promote it to Domain Controller but the wizard gives me some errors.
I've investigated further and I get this error with adprep /rodcprep (with elevated privileges):
Adprep could not contact the Naming FSMO myserver.mydomain.com The Naming FSMO must be reachable for this operation proceed.
Error code: 0x3a
I am trying to do this logged as Domain Admin and I've checked Netdom Query FSMO on both the new server and the main server:
All the entries point to the same server: myserver.mydomain.com on both sides (new server and main)
The new server has not the DNS sever role and has as single dns server the main server.
What is wrong?
How can I fix this?
