Switching Between Wireless Locations

I have a home wireless network that automatically assigns the IP address and
info to my new laptop (Vista). At work, I'm required to manually enter the
IP address and subsequent info to get WiFi.

Is there a way in Vista to set up two different "profiles" or "locations"
that I can easily toggle between to change my IP settings, so I don't have to
go into the Network Connections and change them every time I switch between
the two places?

If Vista cannot do this, is there a program I can purchase/download that
will do it for me?

Thanks!
