I am using XP and have been trying to get my media to share to my xbox 360 and at first the system said I had an ip address issue, even though I could connect to the internet. Now however, it won't find the pc. Upon going to Window Media Player's library/media sharing section, I am prompted with this message: Media sharing has been turned off because a required Windows setting or component has changed. I have tried all of the obvious quick fixes and nothing works, does anyone have any suggestions as Microsoft is less than helpful telling me something, somewhere has changed? Thank you.
