From 0293869b1f6012d1f106e4ab1bd392cea1c66ff0 Mon Sep 17 00:00:00 2001
From: Richard Sharpe <sharpe@samba.org>
Date: Sun, 18 Feb 2001 10:36:03 +0000
Subject: Fixes to libsmbclient so it will work when browsing real Windows
 systems which only respond to port 138 when dealing with NetBIOS datagrams.

We use the unexpected packed database.
(This used to be commit 620cc34015ab16d25f7ef7e13cbc3d0f669da11e)
