hi
thanks to everyone who replied. my original question

the limit is set in /usr/include/resolv.h with the
variable MAXNS. the default value for Sun OS 4.1.4
is 3. this is also given in the man page on resolv.conf.
i checked and no one here has rebuilt and
installed newer versions of bind.
the general consus was that additional nameserver
entries are ignored. evi smith's book,
_UNIX System Administration Handbook_, states that
Bind begins with the first name server listed in the
resolv.conf file, and queries each server 4 times
before going to the next entry.
several people reminded me that the version of Bind
shipped with 4.1.4 is old, outdated, and buggy. i
will look into building and installing the latest version
after i get this DNS subdomain set up and running.
the current maintainer of Bind is the Internet Software
Consortium at www.isc.org. they have links to a lot of
useful things there.
