Okay.... First you put this vbscript in Computer Configuration > Windows Settings > Scripts > Startup section. Now when you restart the computers, it will do the following.... Will set the USBSTOR key's startup value to 4 (original is 3). This will not let the USB Mass Storage devices start. Will deny anyone's access from usb.inf, usb.pnf files. This will deny any newer devices from getting detected.... Please test & share results...

Kindly suggest methods, I'm a novice in this... best regards Ananth. --------------------------------- Yahoo! Mail is the world's favourite email.
