raise the domain function level to windows 2000 native

Raise the domain functional level

CAUTION: Do not raise the domain functional level if you have, or will have, any Windows NT 4.0 or earlier domain controllers. As soon as the domain functional level is raised to Windows 2000 native or Windows Server 2003, it cannot be changed back to a Windows 2000 mixed domain.

1. Log on the PDC of the domain with domain administrator credentials.

2. Click Start, point to Administrative Tools, and then click Active Directory Domains and Trust.

3. In the console tree, right-click the domain for which you want to raise functionality, and then click Raise Domain Functional Level.

4. Under Select an available domain functional level, do one of the following: • Click Windows 2000 native, and then click Raise to raise the domain functional level to Windows 2000 native.

-or-

• Click Windows Server 2003, and then click Raise to raise the domain functional level to Windows Server 2003.

Note You can also raise the domain functional level by right-clicking a domain that appears in the Active Directory Users and Computers MMC snap-in, and then clicking Raise Domain Functional Level. To raise the domain functional level, you must be a member of the Domain Administrators group.

The current domain functional level appears under Current domain functional level in the Raise Domain Functional Level dialog box. The level increase is performed on the PDC FSMO and requires the domain administrator.
