Windows 7 Wont Add Media Extender

[Neodude1123201]

So basically what im trying to do is stream my music to my 360. My 360 Connects to my router via ethernet and my pc via WIFI,On my PC the 360 shows up under 'media devices' on my network but my 360 cant find my pc and when i try to connect through media center it says it cant communicate with the extender yet uPnP Is enabled,ICS is disabled and all firewalls are off.

Any ideas?


Yet my parents computer which is running vista home premium finds it no problems.
