Right.  If you don't have a workgroup name, there's no way to find *any*
master browser unless you broadcast for it.

...well...  Samba offers a non-standard enhancement that can be leveraged 
in this case.  If you don't find any MSBROWSE nodes using the broadcast, 
you can *try* sending a query for *<1B> to the NBNS.  If the NBNS is a 
Samba server it will return a list of all known DMBs.

I *think* that this may be done via the non-standard UDP-based LDAP-like
protocol that Microsoft has put together.  Anthony Liguori is the only 
person I know who has studied that protocol.
