Updated: January 21, 2005

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

To enable schema changes on a schema master running Windows 2000

  1. Open Registry Editor.

    Caution

    • Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer. You can also use the Last Known Good Configuration startup option if you encounter problems after manual changes have been applied.

  2. In Registry Editor, navigate to the Parameters registry key:

    Where?

    • HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/NTDS/Parameters

  3. On the Edit menu, click New, and then click DWORD Value.

  4. Type Schema Update Allowed, and then press ENTER.

  5. Double-click the Schema Update Allowed registry key that you just created, and then, in Value data, type 1 to enable schema changes.

Notes

  • To perform this procedure, you must be a member of the Domain Admins group or the Enterprise Admins group in Active Directory, or you must have been delegated the appropriate authority. As a security best practice, consider using Run as to perform this procedure. For more information, see Default local groups, Default groups, and Using Run as.

  • To open Registry Editor, click Start, click Run, type regedit, and then click OK.

  • To disable schema changes, in the Schema Update Allowed registry key, under Value data, type 0.

  • This procedure should only be performed on a domain controller that is running Windows 2000 and that also holds the schema master role.

Information about functional differences

  • Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
