are placed in the Built-in folder. Note that these special Container objects are not organizational

units. They cannot be moved, renamed, or deleted.

Existing Windows NT Server 4.0 and earlier groups are located in different folders depending on

the nature of the group. Windows NT Server 4.0 and earlier built-in local groups (such as

Administrators and Server Operators) are located in the Built-in folder. Windows NT Server 4.0

and earlier global groups (such as Domain Admins) and any user-created local and global groups

are located in the Users folder.

The upgraded PDC can synchronize security principal changes among the remaining Windows

NT Server 4.0 and earlier BDCs. It is recognized as the domain master by servers running

Windows NT Server 4.0 and earlier BDCs.

If a domain controller running Windows Server 2003 goes offline or otherwise becomes

unavailable, and no other Windows Server 2003 domain controllers exist in the domain, a

Windows NT BDC can be promoted to a PDC to fill the role for the offline Windows Server 2003

domain controller.

The upgraded domain controller is a fully functional member of the forest. The new domain is

added to the domain and site structure, and all domain controllers receive the notification that a

new domain has joined the forest.

Upgrading Any Remaining BDCs

After you have upgraded the Windows NT Server 4.0 and earlier PDC, you can continue to

upgrade all remaining BDCs. During the upgrade process, you may want to remove one BDC

from the network as a precaution in case a problem develops. This BDC stores a copy of your

current domain database.

If any problems arise during the upgrade, you can remove all domain controllers running Windows

from the production environment, and then bring the BDC back into your network and make it the

new PDC. This new PDC then replicates its data throughout the domain so that the domain is

returned to its previous state.

The only drawback to this method is that all changes that were made while the isolated BDC was

offline are lost. To minimize this loss, you can periodically turn the offline BDC on and off—when

the domain is in a stable state—during the upgrade process to update its copy of the directory.

When upgrading Windows NT Server 4.0 and earlier domains, only one domain controller running

Windows Server 2003 can create security principals (users, groups, and computer accounts).

This single domain controller is configured as a PDC emulator master. The PDC emulator master

emulates a Windows NT Server 4.0 and earlier PDC. For more information about the PDC

emulator role, see “Operations Master Roles” in the Windows Server 2003 on-screen Help and

Support Center.

Converting Groups

When you upgrade a PDC running Windows NT Server 4.0 to a server running Windows Server

2003, existing Windows NT groups are converted. Specifically, when the Windows Server 2003
