Quickfix, create /etc/hosts entries on Samba box for internal IP's.

I am running Samba version 2.2.3-pre and have run into a slowdown.  This
doesn't seem to be a problem for my account (mapped as root), but it
creates a delay in the session setup for my users.  The delay can be
anywhere from 30 seconds to over a minute.  I cannot find a true cause, as
the computer name is resolved correctly.  These are NT4.0 clients, and they
are only in WINS, so no DNS entries for them or /etc/hosts / lmhosts
entries.
Consequently, I don't even have an lmhosts file.

Here is a snippet of the log @ level 3 (sorry, don't have too much disk
space, have 6 gigs of logs currently).
I have 900 users on this particular server, though load is low.  The only
similiar errors I could find where reported back in 1997.

Thanks for your help, and let me know if there is anything else needed.
