USB Key reminder script

Here’s something for all you windows network admins out there.
(I apologize in advance to Johnathon’s linux followers)

Here’s a little script I wrote to be used as a group policy logoff script to remind users to remove their USB memory sticks/keys when logging off.

I wrote it while working in IT Support for a High School, to help out our IT teachers and ourselves as we were weekly gathering a collection of various USB Memory Sticks and memory keys (and since i was the one trying to reunite them with their owners each week.)

It’s written in VBS so it’s perfect for using as a group policy in active directory on say a Windows 2003 server/XP network. I haven’t tried it on Vista, Windows 7, or Server 2008 because I wasn’t using those technologies at the time, but it will most likely work with Vista and Windows 7 when deployed from a 2k3 or 2k8 server.

It detects removable drives (the type it looks for can be modified) that are connected and won’t pop-up without a drive detected.

If a USB drive is connected, it pops up a dialog reminding the user to take their memory stick with them and then auto-closes after a few seconds (as not to hang the logoff procedure).

I hope this is usefull to someone. If you use it, please leave me a comment.

‘ MODIFIED to detect only removable drive. GTinsley 2008 @ Wallington County Grammar School.
‘  May cause false positives on some SATA ‘puters.
‘  Tested working on ‘puters with card readers.

Set FileSystemObject = CreateObject(“Scripting.FileSystemObject”) ‘Create a filesystem object
Set Drives = FileSystemObject.Drives ‘Create a drives collection

‘ Step through the drive collection, and get both the drive letter and the drive type.
‘ There are 6 distinct types of drive:
‘Select Case DriveType
‘   Case “0” DriveType = “Unknown type of drive”
‘   Case “1” DriveType = “Removable drive”
‘   Case “2” DriveType = “Fixed drive”
‘   Case “3” DriveType = “Network drive”
‘   Case “4” DriveType = “CD-ROM drive”
‘   Case “5” DriveType = “RAM Disk”
‘End Select

For Each DiskDrive in Drives

DriveLetter = DiskDrive.DriveLetter
DriveType = DiskDrive.DriveType

‘ Check for a removable drive connected that:
‘     Is not the drive letter A B or C
‘    Folder exists (proves the drive exists)
IF Drivetype = “1” and not driveletter = “C” and not driveletter = “A” and not driveletter = “B” and FileSystemObject.FolderExists(driveletter & “:\”) then

‘ Old method. Waits until user has clicked OK before logoff completes.
‘WScript.Echo “The removable disk drive ” & DriveLetter & ” is a still connected. Don’t forget your USB drive!”

‘ New method waits 5 seconds then logs off.

Set objWSH = WScript.CreateObject(“Wscript.Shell”)     ‘ create object

‘ Clear objects and collections

    Very useful!
    Thanks for that!

    Now I only have to search for a possibility to abort or delay the logoff/shutdown command until the USB Device is not connected anymore.
    This way the users can’t logoff until the device is uplugged.
    I know it works with WM_QUERYENDSESSION, but how exactly I still have to find out.

    So if you got time and want to script, here is your chance ^^

    Much thanx
