Site specific logon scripts

I have a network with multiple locations, and staff move around between sites pretty frequently, using different computers. Most of them aren’t very computer literate, so I have been using login scripts to connect to network drives and printers.

I am trying to use a GPO for computers at each site, with a user logon script that connects the printer at that site, but the script isn’t running. I’ve set loopback policy processing to on, but no luck. The same script applied directly to users works fine.

Suggestions?
