If you're having problems getting media sharing under windows media player working, after first checking you don't have a firewall blocking upnp connections or anything like that, I suggest giving xbmc for winodws a go.

download the latest build and set up the upnp. I use it because upnp for media player is disabled on Server 2008. Works like a charm.
@makingmusic476 Never had a problem with the two working together.
