Windows Server 2003's Microsoft Management Console (MMC) Group Policy Management Console (GPMC) snap-in installs COM objects that support automation through scripting, opening up a world of possibilities when dealing with Active Directory (AD) Group Policy Objects (GPOs). (For details about the GPMC, see "Related Reading," page 6.) Building on the capabilities I discuss in "Scripting Group Policy Searches," November 2003, http://www.winnetmag.com/windowsscripting, InstantDoc ID 40231, and "Scripting Group Policy Objects," October 2003, InstantDoc ID 39856, you can use GPM objects to add or remove the Read and Apply Group Policy permissions for security principals on AD objects such as GPOs, Scope of Management (SOM) objects, and Windows Management Instrumentation (WMI) filters. (To set Deny or Custom permissions on these objects, you still need to use Active Directory Service InterfacesADSItools such as IADsSecurityDescriptor or Microsoft's adssecurity.dll.) . . .
