I've already posted at xbox.com, but I'd like to ask you all if you can help with this problem or point me to another forum that can help me. My xbox360 just came today, and I can't get it for the life of me to recognize my computer. It connects to Xbox Live fine, but doesn't want to Media Share. My PC is running : Microsoft Windows XP Home Edition Version 2002 Service Pack 3 My gateway is: 2 Wire Model 2701HG-B Xbox and PC are both connected to Ethernet ports and are recognized by my gateway. I am running McAfee Security Center and have set the network to trusted and added my Xbox as a "Friend" within that trusted network. I also went to the personal firewall settings and attempted to add the ports displayed in the suggestion on the xbox suggestion dialogue. I'm using Windows Media Player 11.0.5721.5154 and enabled Media Sharing by checking the "Share to" check box and allowing the detected Xbox360. All ratings, etc. are allowed by Windows Media Player 11. The problem comes when trying to test the connection to my PC, it seems to correctly connect to the network, but my PC is not listed. Edit: I've now set my router and McAfee Security Center's firewalls to allow TCP on ports 2869 and 10243, as well as UDP on ports 10280-10284, 1900. I've also set my router to allow UDP on ports 2869 and 10243, as well as TCP on ports 10280-10284, 1900. I've also set the already active services SSDP Discovery Service, Universal Plug and Play Device Host service, Windows Media Player Network Sharing Service to Automatic. Still no luck.
