Your network contains an Active Directory domain named contoso.com.
You need to create a central store for the Group Policy Administrative templates.
What should you do?

A.
Run dfsrmig.exe /createglobalobjects.

B.
Run adprep.exe /domainprep /gpprep.

C.
Copy the %SystemRoot%\PolicyDefinitions folder to the
\\contoso.com\SYSVOL\contoso.com\Policies folder.

D.
Copy the %SystemRoot%\System32\GroupPolicy folder to the
\\contoso.com\SYSVOL\contoso.com \Policies folder.

Creating an ADMX central store for group policies
To take advantage of the benefits of .admx files, you must create a Central Store in the
SYSVOL folder. The Central Store is a location that is checked by GPMC. The GPMC will

use .admx files that are in the Central Store. The files that are in the Central Store are
replicated to all domain controllers in the domain.
First on a domain controller (Windows Server 2008/2008 R2) the ADMX policy definitions
and language template files in %SYSTEMROOT%\PolicyDefinitions need copying to
%SYSTEMROOT%\SYSVOL\domain
\Policies\PolicyDefinitions.
Run the following command to copy the entire folder contents to SYSVOL. This will then
replicate to all domain controllers (the default ADMX policies and EN-US language templates
(ADML) are about 6.5 MB in total).
xcopy /E “%SYSTEMROOT%\PolicyDefinitions”
“%SYSTEMROOT%\SYSVOL\domain\Policies
\PolicyDefinitions\”

Next ensure you have remote server administration tools (RSAT) installed on your client
computer you are using to edit the GPO’s. This will need to be Windows Vista or Windows 7.
For Windows Vista enable the RSAT feature (GPMC).
For Windows 7 download and install RSAT then enable the RSAT feature (GPMC).
When editing a GPO in the GMPC you will find that the Administrative Templates show as
“Policy Definitions
(ADMX files) retrieved from the central store”.
This confirms it is working as expected.
