So it´s time to phase out a older DC and demote it?
Here´s a basic description of how to:
There is a total of 5 roles that needs to be transferd before demoting and uninstalling the DC roles on the existing DC:
- RID master
- PDC Emulator
- Infrastructure master
- Domain naming master
- Schema master
To confirm where the roles are located:
Start cmd.exe and type:
netdom query fsmo
Now you should get a list of all FSMO roles and witch server that holds the specific role:
Transfer RID Master, PDC Emulator, and Infrastructure Masters
Open the Active Directory Users and Computers
Right-click the Active Directory Users and Computers icon again and press Operation Masters.
Select the appropriate tab for the role you wish to transfer and press the Change button.
Transfer Domain Naming Master Role
Open the Active Directory Domains and Trusts
Right-click the Active Directory Domains and Trusts icon again and press Operation Masters.
