[jcifs] Network name resolve time

[Michael B Allen]

Hi yankings,

Your program doesn't make any sense. You set resolveOrder to do WINS
but you don't set a WINS server. Then the next method in the list is
DNS but the name given is not DNS name.

In general, you should no longer be using NetBIOS names. You should
use DNS only and always use a fully qualified DNS hostnames. Sometimes
you can use only the first label of the DNS hostname but in this case
your OS must be configured with a suitable DNS search suffix.

A proper JCIFS program should probably just set resolveOrder=DNS. But
LMHOSTS and WINS are still enabled by default just in case someone's
trying to connect to a Windows 98 machine.

Mike
