Please put the information on what you are trying to solve such as version and info on the dataprotector (I checked Sunsolve and they had no documents containing that).

Your original message did not mention dataprotector -

anyone ever seen this problem

with /etc/nsswitch.conf forcing the system to look in files then dns
but the system ignores the files and goes off check the dn servers
The answer for that is yes, some application software actually does not look at nsswitch.conf or /etc/hosts without setting it up to look at them (example: Sendmail - uses DNS only unless you set it up differently).

Your test that Optimus_P asked you to try was sucessful as far as I can see. When you had only dns in the nsswitch.conf your system did not know what testftp was (ping to a IP address will always work since it's not using /etc/hosts or DNS to find out an IP for a hostname). When you put files and DNS in nsswitch.conf, then the ping to testftp worked (it found it in /etc/hosts).

And nslookup will not look at nsswitch.conf as it is a DNS only query tool to check that DNS is working

check-permissions

check-permissions(1M)					  System Administration Commands				     check-permissions(1M)

NAME

       check-permissions - check permissions on mail rerouting files

SYNOPSIS

       /usr/sbin/check-permissions [login]

DESCRIPTION

       The   check-permissions script is intended as a migration aid for sendmail(1M). It checks the /etc/mail/sendmail.cf file for all configured
       alias files, and checks the alias files for :include: files. It also checks for certain .forward files. For each file  that   check-permis-
       sions checks, it verifies that none of the parent directories are group- or world-writable. If any directories are overly permissive, it is
       reported. Otherwise it reports that no unsafe directories were found.

       As to which .forward files are checked, it depends on the arguments included on the command line. If no	argument  is  given,  the  current
       user's home directory is checked for the presence of a  .forward file. If any arguments are given, they are assumed to be valid logins, and
       the home directory of each one is checked.

       If the special argument ALL is given,  the passwd entry in the  /etc/nsswitch.conf file is checked, and all password entries  that  can	be
       obtained through the switch file are checked. In large domains, this can be time-consuming.

OPERANDS

       The following operands are supported:

       login	Where login is a valid user name, checks the home directory for  login.

       ALL	Checks the home directory of  all users.

FILES

       /etc/mail/sendmail.cf	Defines environment for  sendmail

       /etc/mail/aliases	Ascii mail aliases file
