     a.  What components are in the network?
     b.  How are they connected to each other?

For example:
     modem (cable/dsl)
          ---> home router (wired or wireless?)
                 ---> laptop computer (wired or wireless)
                 ---> X-box 360 (wired?)

2.  Reference(s).  Maybe the "Xbox LIVE Support site":
     a.  http://support.xbox.com/support/en/us/xbox360/xboxlive/default.aspx
     b.  Windows ICS Connection
     C.  Router Connection
     d.  Wireless Connection
     e.  Direct Modem Connection

Here's what Microsoft says for Windows XP:
     f.  Connect an Xbox or Xbox 360 to your network
     g.  Setting up your network
     h.  Windows XP: Networking your home or small business

or Vista:
     i.  Setting up a home network

and here's a well organized third party site for home network HELP (has Vista Tips):
     j.  http://www.home-network-help.com/index.html modem (dsl)
