You'd have to show us directory listings and group associations
otherwise how would we know? You should not have to change permissions
on nagios.cmd as it will be created by nagios with the correct ownership
and permissions if you've followed the documentation at
http://nagios.sourceforge.net/docs/1_0/extcommands.html and
http://nagios.sourceforge.net/docs/1_0/commandfile.html. The named pipe
is also removed and re-created at each nagios restart so any changes you
made would be transient anyway.
 
> Anyone have any suggestions?

Turn on nsca debug and watch your messages file. Enable
'log_passive_service_checks' in nagios.cfg and watch for them in
nagios.log. Look for errors in nagios.log. Make sure you have
check_external_commands enabled with a reasonable
command_check_interval.
