I want to hide external hard disk drives connected on win 2008 r2 server through USB on the rdp session of Limited user (non-administrator). When a administrator logs on to the server through he should see all the drives (Removable Hdds and Pendrives) and could access them. When a limited user logs through he should see the internal drives of the server (as he has rights). Please note that a external Hdd gets different drive letters when connected at different conditions.
I am not a expert person so please be lenient and tolerant while answering.
