Windows Media Player Sharing and NIS

I recently purchased a wireless Internet Radio (Sanyo R227) which is capable of accessing shared media libraries on the same wireless network.  After going through the settings for media sharing, I was unable to get it to work.  After disabling SmartFire, it worked fine. 

 

I have changed the settings for Windows Media Player and Windows Media Player Network Sharing Service to Allow.  Still does not work.

 

My firewall has all the defaults.  I have never changed anything in the two years I have had the laptop, and NIS is the most up-to-date version.

 

 Any suggestions?
