Below are the procedures on how to setup and create a central store for ADMX files.

1. On your primary DC, create a folder name “PolicyDefinitions” under the “%systemroot%\sysvol\domain\policies\” path

e.g. %systemroot%\sysvol\domain\policies\PolicyDefinitions

2. Create a subfolder for each language

e.g. for English,

%systemroot%\sysvol\domain\policies\PolicyDefinitions\EN-US

3. Copy all the current local ADMX files into the new folders

e.g.

To copy all files inside the PolicyDefinitions folder:

xcopy %systemroot%\PolicyDefinitions\* %logonserver%\sysvol\%userdnsdomain%\policies\PolicyDefinitions\

To copy all files inside the PolicyDefinitions En-US folder:

xcopy %systemroot%\PolicyDefinitions\EN-US\* %logonserver%\sysvol\%userdnsdomain%\policies\PolicyDefinitions\EN-US\

4. Wait for the FRS process to copy all the files to all domain controllers

5. Once files have been copied, create a new Group Policy object and it should now read the ADMX files from the domain base location.
