No. The optimal method is to specify jcifs.smb.client.domain and
jcifs.netbios.wins. When retrieving the address of a domain controller in
that domain, WINS is queried for a list of hosts from which one will be
selected using a very simple "load balancing" algorithm. If the selected
host does not respond it will be removed from contention and another host
will be selected.

If this is not suitable then you should provide a detailed explaination
along with any associated errors you might be getting.
