PDC Emulator in AD emulates an NT4 PDC for NT clients

by ManiacMan In reply to PDC Emulator in Windows N ...

The DC running the PDC Emulator FSMO role does a few things:

1. Provides time services for the domain
2. Facilitates password changes for the domain
3. Acts as an NT4 PDC for legacy clients and servers, such as NT4 BDCs' and NT4 workstations.

There is no such thing as a PDC or BDC in Active Directory, as every DC is replicating in what is known as multi-master mode. Every DC can accept changes and update the AD database within the domain or forest.

If the DC holding the PDC emulator role is down, password changes will not be processed and you'll get errors until you bring the DC back up or transfer or seize the role to another working DC.

If you have multiple domains within a forest, each domain will have at least one DC that's hosting the PDC emulator role. Also, the first DC in a new forest or domain will automatically get the PDC emulator FSMO role, as it's required.
