Jonathan- If you have Vista clients then Vista GP supports this. If not, then Group Policy Preferences supports device restrictions but you can either only enable or disable a given device class-there is no granularity to allow reads but not writes, as there is in Vista.

I have a custom ADM that disables writing to removable media but USB keys are still permitted. That solution won't work. I also have a custom ADM that disables the cdrom.sys driver. Reading from CD-Rom drives is still kosher as well, so that doesn't work. Any suggestions? Jonathan Finkbiner Support Analyst Information Services Lifestyle Family Fitness
