Application and Device Control Policy
In Endpoint Protection Manager (version 12.1.2015) I created a policy and tested it on my own workstation. Under Device Control\Blocked Devices I added "CD/DVD Drives". It worked Great! My DVD drive totally disappeared. BUT ... Now I want my DVD drive back so I removed "CD/DVD Drives" from the list ... however, my DVD drive will not reappear.
In my client I have updated the policy profile. I have waited 2 days and have reboot my system several times.
