roscoe - this will sound utterly ridiculous but it's true. Provided you've allowed all the necessary ports, etc. - chances are you've already done what you needed to do.

1. IGNORE THE TEST!

2. Goto your music library (or whatever you're trying to pick up) on your Xbox 360 and then change the source - you should see (hopefully) the Zune logo and your computer name. Select it and away you go.

If this doesn't work - you'll need to ensure that all necessary windows services are enabled. (sorry don't have a link but google it) and ensure that your Xbox is not being blocked from your PC as it needs to make an incoming connection.
