How can I connect Win7 Home to office internet?

I have a sbs 2003 server running DHCP and DNS servers. Have about 7 clients running XP pro that have access to the domain and internet.

Now the bosses just purchased laptops that came with Windows 7 Home edition. I have no requirements for them to access the domain or LAN (Home version will not handle a domain anyways), but would like internet access when the laptops are within wireless range.

The Win7 laptops are assigned an IP address by the DHCP server, and I can see the clients and server in our LAN from them, but cannot get through to the internet.

I am normally quite computer savey, but simply not familiar enough with sbs to solve this on my own. Any direction is greatly appreciated.
