I had a request from a client to deny certain Win7 computers the ability to write optical discs from their local CD/DVD burner/drives. I used the GPO at Computer Configuration > Policies > Administrative Templates > System > Removable Storage Access > CD and DVD: Deny write access. I linked the GPO to an OU in which I placed the appropriate computers. This worked great! However, I got another request to ALLOW one of those same computers to burn discs again. So I just moved the computer back into the same OU as the other computers that always had burn rights, did a gpupdate /force on both the server and the client, rebooted the client, but the burner software displays the message that the user has no burn rights still. I then created a GPO that explicitely ALLOWED burn rights, but still no joy. What will it take to get the burn rights reassigned to these computers? Thanks!
