That's a good sign and definitely narrows down what the issue could be.
To be clear, can you provide the entire output from the unsuccessful
check from nagios.log? As far as what else to check, are you certain
that $USER1$ is /usr/lib/nagios/plugins and that $HOSTADDRESS$ is
192.168.100.20? It might be helpful to see the actual command that
nagios is running by changing the command{} definition to be --

command_line    echo "$USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v
$ARG1$ $ARG2$"

It won't actually run check_nt but you'll see what nagios would be
doing. Did you change this check from some other configuration? I'd
restart nagios either way and while doing so, verify that you don't have
multiple nagios processes running.

Sounds like you either haven't completely followed the instructions on
enabling external commands or that you have SELinux or some other
permissions issue preventing the web server from accessing that file.
You should verify that your configuration matches the nagios
documentation for enabling external commands (using your rpm specific
paths of course) and that you've restarted your web server if you
changed it's group membership.
