Vista - vb script help

I have a VB Script that I am running using my Group Policy Editor to
delete user profiles during logoff (running Windows XP) . The script
works fine when I am logged in as administrator, but when individual
users logoff they get an insufficient authority error message associated
with the delete line of the script. Does anyone know if there anyway
around this problem ? See script below ...

' Set up the scripting environment
Option Explicit
Const oSrc = "C:\Documents and Settings\20*"
Dim Text, Title
Dim WSH, FSO, oFolders, oFolder, oSubFolders ' Object variables
Dim oFileCount, oFolderCount, oFiles, oCount
Text = "Folders" & vbCrLf & vbCrLf
' Dialog title (inc. vanity bit)
Title = "Student Profile Deleter"

' Create Windows Scripting Host Shell object
Set WSH = WScript.CreateObject("WScript.Shell")
' Create FileSystem object to access the file system.
Set FSO = WScript.CreateObject("Scripting.FileSystemObject")

'Delete the folder (forcibly, to handle read-only attributes)
FSO.DeleteFolder oSrc,True


'Free memory used by objects
Set WSH = Nothing
Set FSO = Nothing


WScript.Quit()

Thanks in advance

FSO.DeleteFolder oSrc,True

Attempting to delete your own profile folder while logged on is equivalent
to sawing off the branch you sit on. Windows won't let you do it and writing
a script around it makes no difference. Try doing it from Explorer or a
Command Prompt - it won't work either!

Note that profile folders are often locked until you reboot the machine.
While they are locked nobody can delete them, not even an administrator.
