I'm trying to setup wmp11 to share my media with my xbox360 over my wireless network. when i try to turn media sharing on i get an error messege "Media sharing has been turned off because a required Windows setting or component has changed. For additional assistance, click Web Help" the "web help" page tells me "You've encountered error message C00D0FF4" and carries on explaining to me how to manually start the Windows Media Player Network Sharing Service using the "services" tab of the computer management page. the big problem with that is that i cant find anything to do with windows media player on that page. lots of windows media center services but no media player services. this is really starting to drive me crazy! soon I'll just have a broken xbox stuck in the middle of my computer screen. any help would be very appreciated.

Is it Windows 7? Change your account settings to make the OS Windows 7. It says Vista. If it is Vista, how did you get Media Player 11 for it?

Anyway, this solution is for Windows Vista, and may be slightly different for Windows 7. In the Network and Sharing Center, there is an option 'Media Sharing'. Enable it.
