Server 2008R2 datacenter Hide drives

Hello

I want to hide drive A to J on the server for the users on RDP.

when I want to do that in the GPO for users I can only chose drive A,B,C and D.

Any idea ??

I have changed the windowsexplore.admx file so it contains:

          <item displayName="$(string.AtoJOnly)">
            <value>
              <decimal value="1023" />
            </value>
          </item>

And the windowsexplore.adml file contains:

      <string id="AtoJOnly">Restrict A to J drives only</string>

I can see the: "Restrict A to J drives only in:"Hide these specified drives in My Computer" but when I enable it I still can see the F, D and G drive. The C and E drive are hidden.

Any idea ?
