Symantec Endpoint Protection doesn't block usb drives in windows xp
I'd like to share some problem that I have in the company that I work. We have installed Endpoint protection (22.214.171.1241.401 RU1 MP1) in 200 computers located in 2 sites (two cities). Everything works fine, except that I want to block usb storage to the computers. I made a policy for that and works fine for the computers in my first site (both windows xp and 7 OS), but in the second site the policy only works for windows 7 computers. The policy is the same for both sites. I've also tried to add USBSTOR* in device ID to block, but it still works only for windows 7 computers. Can someone give an advice?
