windows 7 - Local group policy for all users

Windows 7, 64bit.

I have two simple .bat scripts created, one which runs at logon, the other at logoff. The .bat files are located in C:\bat. Other users have access to this folder.

The contents of each .bat file are below (basically disable/enable a specific device using devcon.exe);

disable.bat

devcon disable "FTDIBUS\COMPORT&VID_0D2C&PID_032A"

enable.bat

devcon enable "FTDIBUS\COMPORT&VID_0D2C&PID_032A"

I set the group policy logon/logoff script by doing the following;

• logged into my PC as the local administrator


• start > run > gpedit.msc


• user configuration > windows settings


• scripts (Logon/Logoff)


• added my two .bat files to Logon/Logoff respectively

The scripts do work but only when I am logged in as the local administrator (the user that created the policy). When another (non-admin) user logs on, the scripts seem to be ignored.

How can I set this up so that the scripts run for each and every user that logs on to the PC?

This PC is part on an AD domain which I have no control over.

I'm unable to run the .bat files manually when logged in as a non-admin user. Presumably this is because the .bat files are trying to disable a device in device manager. Non-admin users can't disable devices in device manager, I receive an error when trying to do that.

Any help is appreciated.
