Here’s a cheat sheet for transferring Operations Master Roles:
There are 5 Roles:
- Domain Naming Role
- Schema Role
- RID Master
- PDC Emulator
DOMAIN NAMING ROLE:
Open Active Directory Domains and Trusts, Right click on Active Directory Domains and Trusts and select Operations Master.
First you’ll need to register schmmgmt.dll. Start Run ‘regsvr32 schmmgmt.dll’
Then Start RUN ‘MMC’, add the snap in Active Directory Schema, right click Active Directory Schema and select Operations Master.
INFRASTRUCTURE, RID MASTER, PDC EMULATOR:
SEIZE THE ROLES:Open Active Directory Users and Computers, right click your domain name and select Operations Master.
Only after the above fails and you need the next step, see about repadmin and ntdsutil seizing.
