Except that the current default is "name resolve order = lmhosts wins
host bcast" which I think it quite useful.

I see the 'host' name resolve type for <00> names (which will often have
a one-to-one mapping to netbios names) to be quite useful.  

What I'm worried about is the lookups for _tcp._ldap.DOMAIN, which would
ocour when looking for an ADS DC, but which *will not* find the
answer.   Naturally, this won't occur if the domain is validly in WINS,
but this doesn't always happen.  Currently, if I understand this
correctly, we will do a DNS lookup (which we know will fail) *before* we
broadcast.  Why do that lookup (which is not a normal 'hosts' lookup) at
all?

This is a very special case of lookup, why not deal with it as such?
