If you aren't using managed switches then XP will default to IGMP V3.  If
you are then it should adapt to the IGMP version the switch is using.  I
have no idea if it will respond to a ping on multicast.  I wouldn't count on
it.  It may be that the IP stack filters out packets received on a multicast
address that are not on a joined socket.
