In all of this discussion I don't see any mention of /etc/netsvc.conf, so I
will just post this reminder: which gets used first, /etc/hosts or DNS, is
controlled by /etc/netsvc.conf. A record in that file with
hosts=local,bind
will cause the local /etc/hosts file to be consulted before DNS. Reverse
that if you want DNS consulted first.

Subject: Re: [NV-L] Selection Name missing domain suffix
Linda,
Remember that nslookup does not look
at the /etc/hosts file, so it doesn't
really give the complete picture.
Try this: put a bogus entry in /etc/hosts
then do an nslookup on that entry (forward
and reverse) and notice that nslookup won't
find it.
However, the resolver will use /etc/hosts, and
if you have told the resolver (via /etc/resolv.conf)
to use /etc/hosts, then dns, then NetView is going
to do that and pick up reverse names from /etc/hosts
if they are in there. There is no nslookup type
program that queries /etc/hosts, I guess no one
thinks they need it since /etc/hosts is an ascii
file and grep will do fine.
So, if you have added host names into /etc/hosts
without the domain suffix, NetView will eventually
find and use them.
