View files share by upnp server with windows media player 11, vist

I have a Upnp server and its on linux system, I am sharing files through a upnp server. I am not able to see share icon under the network. I have enabled my upnp media sharing in wmp11. But still I cannot see the icon or view upnp server in wmp 11. Does it have any kind of limitation that wmp11, see files shared by other wmp11 upnp server only ? Can you please help to fix this problem ?

Well as far as I know there is no such kind of limitation. I have NLSU here, which offers Samba shares instead. It really works great media player and iTunes, and regarding media share is added to the media player library by pressing f3 button and browsing to the music storage directory on the file share.
