Hello there, I am having the same exact problem; thank you for the suggestion of restarting the UPNP Device Host; unfortunately this did not work for me. I have been working on this for a few days now; here is what the situation is: - XP Home, MCE - Xbox 360 - Using a wireless router - Linksys WRT54G - This has worked before - I have been using the Media Extender for about a year now; it just suddenly stopped working - I have Norton Internet Security. I have added all of the required programs as exceptions (allow all); I have even gone as far as to uninstall the entire program and disable Windows Firewall and it still does not work (can't find an Xbox 360 on the network) Any help is greatly appreciated... thanks!
