"Got an Xbox 360? You're probably already using it to frag friends in Halo 3, take down Big Daddies in BioShock, and skulk around in the dark in Call of Duty 4, but if you're not also using it as a home media server, you're missing out. In this step-by-step guide, we'll show you how to set up a UPnP sever on any Windows or Mac computer so the Xbox can access it, and then how to connect and browse your media. That way, when friends come over with their laptops, they can connect to your network and play their digital media too." Digital Trends
