Logon Script for adding a route

Hey guys, I want to add a route to some of my users. The problem is that as they don’t have administrator permissions I can’t do it through a logon.bat file configured in their profile.
I think I have to go with a VBScript pushed through a GPO. My problem is that I couldn’t find something useful to do this, the command I want to run is like this:
route add “DESTINY SUBNET” mask “SUBNET MASK NUMBER” “GATEWAY”

Thanks in advance.
