Problems with dmb/lmb on alpha 0.4

[Michael Breuer]

TNG alpha 0.4 reports that the current master browser for its domian is "UNKNOWN."

More info:

1) in logs(edited) :
    nmbd/nmbd_workgroupdb.c:(307)
        dump_workgroups()
            dump(workgroup on subnet <ip of smb server>: netmask=255.255.255.240
                ... reports correct master browswer
  Then... immediately following this...
        dump_workgroups()
            dump(workgroup on subnet UNICAST_SUBNET: netmask=<ip address of smb server>
                <domain>(1) current master browser = UNKNOWN
2) All attempts mount shares on this domain fail... netlogon requests succeed.

3) smb.conf contains:
    os level = 65
    preferred master = True
    domain master = True
    wins support = Yes
