One of the first things this script does is copy the ini file information to a custom key in the reg.

I am assuming that you have added extra security restrictions?

What OS?

The script needs write access to this reg key

HKEY_LOCAL_MACHINE\SOFTWARE\Logon_Script

or change

$Configregkey = "HKEY_LOCAL_MACHINE\SOFTWARE\Logon_Script"

to point to a spot in the reg that the users have write access rights to. (you will find this in the logon.kix file 12th line down)

let me know if any of that worked
