SYMPTOMS

By default, Group Policy does not offer a facility to easily disable drives containing removable media, such as USB ports, CD-ROM drives, Floppy Disk drives and high capacity LS-120 floppy drives. However, Group Policy can be extended to use customised settings by applying an ADM template. The ADM template in this article allows an Administrator to disable the respective drivers of these devices, ensuring that they cannot be used.

RESOLUTION

Import this administrative template into Group Policy as a .adm file. See the link in the More Information section if you are unsure how to do this.

This template is considered a preference rather than a true policy and will tattoo the registry of client computers with its settings. If this template is moved out of scope of the Group Policy which applies it, the registry changes it makes will remain. If you wish to reverse the settings made by this template, simply reverse the options to re-enable the drivers.
 
Preference settings are hidden by default in the Group Policy template editor. When applying this template, follow these instructions to change the view settings that allow preferences to be viewed.
