HI I've single domain controller (PDC) in the network. Now I want to add one ADC (additional Domain controller to avoid DC failure. My Current PDC is Windows Server 2003 R2 Standard Edition.
Plan ADC is Windows Server 2008 Standard Edition. So I try to run "adprep"on PDC but it was not able to extend Schema. Massage display:
c
Adprep was unable to extend the schema.
[Status/Consequence]
The schema master did not complete a replication cycle after the last reboot. Th
e schema master must complete at least one replication cycle before the schema c
an be extended.
[User Action]
Verify that the schema master is connected to the network and can communicate with other Active Directory Domain Controllers. Use the Sites and Services snap-i
n to replicate between the schema operations master and at least one replication
partner. After replication has succeeded, run adprep again.
I investigate & found that earlier there was two more domain controller, but they are not live now. I guess I need to transfer the FSMO rule first & than need to delete all previous domain.
Any suggestion from you all to perform this task.
Thanks.
