nslookup returns local ip when resolving another servers fqdn on same subnet

Hi,
I have a server (192.168.1.19) running redhat es2.1, it is on a private subnet (192.168.1.0/24) with two other redhat es2.1 machines, 192.168.1.20 and 192.168.1.21. All three are nat'd to public IP's which are pointed to from public DNS. When I try to resolve the fqdn for the other two servers I get their private IP's as the reponse. I cannot figure out where this information is coming from; the private addresses are not in DNS (the publics are in DNS), and the /etc/hosts file only contains the private IP of the server on which it resides and does not contain private IP's for the other two. This problem is identical on all three redhat machines. Resolving these machine's fqdn from anywhere else works fine.

Does anyone know what might be going on with this?
Thanks in advance for any wisdom...

What are the contents of /etc/resolv.conf? Is it possible they are consulting NIS before BIND?

files are as follows:

/etc/resolv.conf
search criticaldatagroup.com
nameserver 206.168.216.6
nameserver 206.168.216.4

excerpt from /etc/nsswitch.conf
hosts: files nisplus dns

/etc/host.conf
order hosts,bind

/etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
204.144.131.19 storm.criticaldatagroup.com storm

thanks!

Oh yeah, NIS is not running.

Thanks.
