Is this a laptop of a desktop?
On my Windows 7 desktop i think it is:
Start->Control Panel->Network & Sharing Center
I only have Windows 7 at work and i really can't view that much without having any administrator rights on the system so all it shows me is out work network. But poke around in there and you may be able to fine it. It doesn't seem to have the "view network connections" under the start menu like XP did which was much easier.
