• PDC emulator. The PDC emulator is a domain controller that advertises itself as the PDC to

workstations, member servers, and domain controllers that are running earlier versions of

Windows. For example, if the domain contains computers that are not running Microsoft Windows

XP Professional or Microsoft Windows 2000 client software, or if it contains Microsoft

Windows NT BDCs, the PDC emulator master acts as a Windows NT PDC. It is also the domain

master browser, and it handles password discrepancies. At any one time, there can be only one

domain controller acting as the PDC emulator master in each domain in the forest.

You can transfer FSMO roles by using a Microsoft Management Console (MMC) snap-in tool.

Depending on the FSMO role that you want to transfer, you can use one of the following three

MMC snap-in tools:

• Active Directory Schema snap-in

• Active Directory Domains and Trusts snap-in

• Active Directory Users and Computers snap-in

If a computer no longer exists, its role must be seized. However, if the server providing an FSMO

role is down, its FSMO roles do not need to be seized necessarily—particularly if the server will be

fixed and brought back online. Care must be taken to ensure a role is not seized if the original

server holding the role will be returned to service. Allowing a situation where multiple servers are

attempting to provide the same FSMO role can cause problems in Active Directory. Provided it is

necessary to seize a role, use the following procedures to seize a role using one of the MMC

snap-ins from the bulleted list.

To transfer the schema master role, do the following:

1. Click Start, click Run, type mmc in the Open box, and then click OK.

2. On the File menu, click Add/Remove Snap-in.

3. Click Add.

4. Click Active Directory Schema, click Add, click Close, and then click OK.

5. In the console tree, right-click Active Directory Schema, and then click Change Domain

Controller.

6. Click Specify Name, type the name of the domain controller that will be the new role holder,

and then click OK.

7. Right-click Active Directory Schema, and then click Operation Masters.

8. Click Specify Name, type the name of the domain controller that you want to hold the schema

master role, and then click OK.
