Xbox 360 and Windows 7 cannot sync

I have been through several forums now and cannot find an answer. I have enabled all sharing over my network for windows media player and my zune software. My windows xp used to sync with my xbox with zune but windows 7 does not seem to want to find the xbox. I have done everything i have read. the only way they can connect is through vuze and I do not want to connect that way. Any help would be appreciated! Also my windows media center seems to be corrupt when starting it automatically comes up with "windows media center has stopped working"

Just to make sure, if both the Xbox 360 and your PC are on, if you to Network, does the Xbox 360 show up there? Additionally in WMP 12, have you enabled Media Streaming? (Go to Stream --> Turn On Media Streaming) Also, have you added the files you want to share to the appropriate libraries?

nvm i got it now i had to go manage my computer and refresh upnp device host it refreshed my zune software too and boom popped up. I enabled everything else for sharing including zune and wmp. What a pain it was, does anybody know why i had to refresh uPnP device host never had a problem in xp.

ok so that didnt actually fix the problem any time i restart my computer i the connection goes away and i just go thru every option possible and then eventually some times they will connect its really frustrating idn what to do!
