[jcifs] problem browsing smb:// on another subnet

I'm trying to browse the network neighborhood on a different subnet
using a version of ListFiles.java modified to specify the local
interface, the default domain, the WINS server on the target subnet, and
restricting the resolveOrder to "WINS". What I want to do is enumerate
domains using the WINS server; but what happens is, without contacting
the WINS server I'm broadcasting on 137 for __MSBROWSE__ and getting a
response from a browser on the local subnet, to which I can't
authenticate (and which won't accept GUEST or anonymous either).
Is there a way to accomplish what I'm after?
Thanks.
Gary
I've included the Jcifs configuration at startup and the tcpdump summary:
