Hi
We are tryiing to introduce 2012 DCs into our root domain.
The schema has updated fine but the domain prep fails, both on the 2012 server we are trying to promote and whilst running it direct from the infrastructure server itself.
Replication is good and AD itself seems happy enough. The account has the necessary rights.
Any help gratefully received.
Thanks
The error log contains:
