	Like I said jCIFS always uses the wildcard style node status. That's exactly what nbtstat
	-A does. Very wierd.

	Apparently that does it too... very strange. I fear the only way to figure this out is to snoop
	it with Ethereal or NetMon. It's either some XP wierdness in which case the code might
	need a corner clause or maybe he's using scope.
