FILTERING GROUP POLICY’S SCOPE By default, settings flow from site to domain to OU. Three ways to control Group Policy settings inheritance –Block Policy Inheritance: –Security filtering –WMI filters

SECURITY FILTERING

WMI FILTERS Windows Management Instrumentation (WMI) Used for queries and filters concerning –Hardware –Software –Operating system type Can be linked to multiple GPOs

WMI FILTER EXAMPLES Table 10-1 WMI Filter Examples T T a a r r g g e e t t C C o o m m p p u u t t e e r r S S a a m m p p l l e e W W M M I I All computers that are running Windows XP Professional Select * from Win32_OperatingSystem where Caption = "Microsoft Windows XP Professional" All computers that have more than 10 MB of availabledrive space on a C: NTFS partition Select * from Win32_LogicalDisk WHEREName= "C:" ANDDriveType = 3 ANDFreeSpace > AND FileSystem = "NTFS" All computers with a modem installed Select * from Win32_POTSModem Where Name = "MyModem" F F i i l l t t e e r r S S t t r r i i n n g g

CREATING WMI FILTERS

GROUP POLICY MANAGEMENT CONSOLE (GPMC) Free add-on tool that can be used to manage Group Policy. Installs on: –Windows XP with Service Pack 1 –Any edition of Windows Server 2003 Can be used for: –Importing and copying GPO settings –Backing up and restoring of GPOs –Executing the Resultant Set of Policy (RSoP) snap-in –Generating HTML reports

INSTALLING GPMC GPMC is not on the Windows Server 2003 CD-ROM. Can be downloaded for free from the Microsoft Web site. In this course, gpmc.msi is on your supplemental CD-ROM. –Double-click the gpmc.msi file and run through the wizard. –Distribute through Group Policy.

DELEGATING LINKING, MODELING, AND RESULTS

DELEGATING WMI FILTERING

PLANNING GROUP POLICY INTEGRATION Create policies at the highest level possible. Limit the number of GPOs created. Create specialized GPOs for policies. Disable unnecessary portions (user or computer). Only apply GPOs to sites when settings are required on a site basis.

RECOMMENDATIONS ON GROUP POLICY INHERITANCE Limit use of the following: –No Override –Block Policy Inheritance –Security filtering

PLANNING ADMINISTRATION AND IMPLEMENTATION OF GPOS Determine which administrators will have policy delegation roles Test policy settings Document the plan
