Explanation:
In earlier operating systems, all the default Administrative Template files are added to the ADM folder of a Group Policy object (GPO) on a domain controller. The GPOs are stored in the SYSVOL folder. The SYSVOL folder is automatically replicated to other domain controllers in the same domain. A policy file uses approximately 2 megabytes (MB) of hard disk space. Because each domain controller stores a distinct version of a policy, replication traffic is increased.
In Group Policy for Windows Server 2008 and Windows Vista, if you change Administrative template policy settings on local computers, Sysvol will not be automatically updated with the new .admX or .admL files.
This change in behavior is implemented to reduce network load and disk storage requirements, and to prevent conflicts between .admX files and.admL files when edits to Administrative template policy settings are made across different locales. To make sure that any local updates are reflected in Sysvol, you must manually copy the updated .admX or .admL files from the PolicyDefinitions file on the local computer to the Sysvol\PolicyDefinitions folder on the appropriate domain controller.
To take advantage of the benefits of .admx files, you must create a Central Store in the SYSVOL folder on a domain controller. The Central Store is a file location that is checked by the Group Policy tools. The Group Policy tools use any .admx files that are in the Central Store. The files that are in the Central Store are later replicated to all domain controllers in the domain.
To create a Central Store for .admx and .adml files, create a folder that is named PolicyDefinitions in the following location:
\\FQDN\SYSVOL\FQDN\policies
