Maybe it's broken. It could be that that code doesn't force NetBIOS to
be used anymore (this is just a guess but it would explain the IP
address - you would have to look at a packet capture to confirm that).
As described in that property's documentation NetBIOS (port 139) must
be used for it to work. And if it is broken I have no interest in
fixing it as the Filter is going to be removed from JCIFS eventually.
