This is the second part, here is the link to the first part : Citrix XenApp – Hiding system drives part 1/2

If you read the first part, now you know how to apply the Microsoft Windows 2003/2008/R2 GPO to hide A,B,C or/and D drives. But what’s happening if you have a E: drive or O: ? You cannot use this GPO anymore, you need to create your own. This is simple to understand how it works, just read what’s follow.

By default the Hide Drives part in the system.adm file look like this :

POLICY !!NoDrives
   EXPLAIN !!NoDrives_Help
      PART !!NoDrivesDropdown          DROPDOWNLIST NOSORT REQUIRED
         VALUENAME "NoDrives"

          END ITEMLIST
