I suspect the problem is that you are trying to modify an HKLM reg key in
the user's security context and they don't have permissions to do that. That
is why a startup script was suggested-because that runs in the LocalSystem
security context.

Hi,
yesterday I tried out the script and it was working fine, we deployed it by
evening and today morning, we got an error message in all the systems, the
error message is attached.
I had applied the script in User Configuration, as most of the users do not
shut down their systems, we wanted the script to be applied while users
logon, instead of when at system start.
Kindly advice.
best regards
Anth.

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...
Regds,
LP

What happens with our old script is that, when users plug in a new usb
device the device gets accepted! I'll test the script you have send and will
let you know as soon as possible, how it fares.
thanks for the help!

Hi all,
We have this script running in our Windows 2003 domain.
@echo off
:: *********DISABLE USB MASS STORAGE DEVICE********
regedit /s "\\Tai3dserver\SYSVOL\tai3d .com\scripts\disable.reg"
"\ \Tai3dserver\SYSVOL\tai3d.com\scripts \subinacl.exe" /keyreg
\system\currentcontrolset\services\usbstor /deny=system
the subinacl.exe deployment was advised by Mr. Ray Lewis, basically what the
script does is, it modifies a registry value such that usb removable storage
devices are not read by the system, but new usb storage devices are getting
accessed, how do i block the modification of this registry value? Kindly
suggest methods, I'm a novice in this...
best regards
Ananth.
