360 PC Connection

Hi, my 360 will not connect to Windows Media Connect. It use to untill I got the ring of death . I recieved my new one and now it wont work on my PC. Everything connects during the test untill you get to PC Connection then it says Failed. I have XP and its connected through ethernet . However it does connect to my Laptop through wireless(its vista). I have WMP11 and everything enabled. Anyone out there that may be able to help? I connect to Live just fine. Ive tried everything, Ive added the other ports that it says to do and nothing works. Been messin around with my firewall and nothing...

Anyways thanks;)

Turn off your firewall completely, especially 3rd party ones.

Make sure UPNP is enabled in your router.

Clear all your media sharing settings and start again form scratch.

Try the media sharing feature in the Zune software, if all else fails.
