Hello

In Vista & 2008 Server the WSD Port Monitor (Web Services for Devices) uses 5357 for GET, 
GETRESPONSE, and directed PROBE, PROBEMATCHES messages.

With 'Network Discovery' on, the firewall lets this traffic in.

Stopping the 'Function Discovery Resource Publication" Service will close the port.  The PC then 
won't be able to solicit wireless devices, or broadcast it's own web based devices, but normal 
windows network shares and wireless networks will be unaffected.  That's as much as I know.

Cheers
Colin
