By following KB 813338 you see that SYSVOL was previously configured by an administrator to filter out ADM files in order to minimize size.
- Use a monitoring solution, such as System Center Operations Manager, to ensure group policy is synchronized
- Manage Group Policy from computers that are running Windows Vista or a later version of Windows by using a centralized ADMX store together with filters. This will prevent further ADM creation. Delete the existing ADM files from SYSVOL.
- Manage Group Policy from computers that are running Windows Vista or a later version of Windows by using local copies of ADMX. (This is the default behavior). This will prevent further ADM creation. Delete the existing ADM files from SYSVOL.
- Use a third party tool to examine group policy synchronization.
- Remove the filters, and let ADM files replicate to all domain controllers.
Do not use Group Policy Verification Tool (gpotool.exe). This tool incorrectly checks group policy file synchronization and is not supported on Windows Server 2008 and later operating systems.
