[Samba] Interdomain trust with different WINS servers

[Juan Asensio Sánchez]

If I am not wrong, "nmblookup -U" connects to a WINS server, which is
configured  "name resolve order = lmhosts wins hosts bcast", so i think nmbd
will try to find the requested name first in lmhosts, then in the wins
database, and so on.

I have not said nothing about nslookup, but i think its behavior is like
"nmblooup -U" (it does not use directly hosts, as nmblookup dos not use
directly lmhosts, or am I wrong?)

Regards.
