Network connection empty in Vista

I have recently wired a home network using a Netgear DG834GT Router, 2 PC's
running XP and this new one running Vista. I want to setup port forwarding on
the Vista PC but even though the network is working fine, when I open 'manage
network connections' it's empty. Ive spent most of the last week searching
for a solution but can't find anything that I can understand with my limited
knowlege.
