I installed Group Policy Management Console (GPMC). How can I undo the changes it makes to the Group Policy tab of my Site, Domain, and Organizational Unit (OU) Properties dialog boxes.

A. When you install GPMC, it replaces the Group Policy tab within the Microsoft Management Console (MMC) Active Directory Users and Computers and Active Directory Sites and Services snap-ins with a button that starts the GPMC, as the figure shows. You can't direct Group Policy management as you could before you installed GPMC.

If you want to continue to be able to change Group Policy from within the standard MMC snap-ins, perform the following steps. (However, I stress that GPMC is a superior interface, and in Windows Server 2003 Release Candidate 2 (R2) and later, GPMC will be built into the OS.)

1. Start the registry editor (regedit.exe).
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MMC\NodeTypes\\{19195a5b-6da0-11d0-afd3-00c04fd930c9\}\Extensions\PropertySheet.
3. Delete the value \{789D9216-FDF0-476e-9D73-058C6A7375C3\}, which has a data name of Group Policy Management.
4. From the Edit menu, select New, String value.
5. Set the value to \{D70A2BEA-A63E-11D1-A7D4-0000F87571E3\} and press Enter, as the figure shows.
6. Double-click the new value and click Group Policy.
7. Close the registry editor.
8. Restart the Active Directory Users and Computers snap-in.

These steps change the tab for the Domains Group Policy tab but not for the OU or Site property dialog boxes. To change these, perform the previous steps but change the registry key according to the values shown in the Table shows.

Note that you don't need to delete the old value that GPMC added; you can have both values, and the property dialog box will display two Group Policy tabs--one that points to GPMC and one that has the old built-in Group Policy management functionality.

To add the old-style Group Policy tab, save the following registry file as restoregp.reg and execute it.

\[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MMC\NodeTypes\\{19195a5b-6da0-11d0-afd3-00c04fd930c9\}\Extensions\PropertySheet\]
