	There's not much room for me to help you here Dani. We're pretty confident
	that jCIFS actually works at this point :~). I think you need to look closer at
	the diagnostics suggested in the FAQ to better understand your network.
	The smb://workgroup/ URL will provoke the client to do a NetServerEnum
	operation on the local master browser. Is it possible that for whatever reason
	the machines have not established a local master browser? Are you on a
	home LAN or running a laptop? Sometime that sort of functionality is turned
	off. Again go through all of the diagnostics outlined in the FAQ particularly
	the part about the nbtstat command. Otherwise we will require a packet
	capture or at the very least a -Dlog=ALL dump.

	WINS is a special server. If you were running a WINS server you would
	know it. It's like DNS.

	Setting the baddr property does not have anything to do with cross subnet

> Also, all the hints from the FAQ didn't help.
	Well then your in trouble because the second question is probably dead on.
