Setting up LPT2 using NET USE

I have 2 XPpro machine on a LAN sharing printers. I need to map the printer on one to LPT2 on the other. I have the user type: NET USE LPT2 \\123456\counter and he gets the following error: The network resource type is not correct. Now I have donethis at other places, and it has worked fine. Any thoughts?
