I am picking up Net::SNMP and have a simple script that worked fine while VPN'd in to work from home. Then I come in this morning (having made zero changes) and now I get the error that the host isn't responding (but I can ping it). I checked my firewall, and it's not blocking the traffic. I've seen posts on the 'net where people had to modify *nix config files, but I'm on Windoze using ActivePerl. The latest version of Net::SNMP that was available is what I'm using (6.0). Any ideas? Code below:

#!c:/perl/bin/perl

use strict;
use warnings;

use Net::SNMP;

my $OID = '1.3.6.1.4.1.9.9.513.1.1.1.1.2.0.23.223.167.189.192';
#my $OID = '1.3.6.1.4.1.9.9.513.1.1.1.1.2';

my ($session, $error) = Net::SNMP->session(
   -hostname => '10.100.10.4',
   -version => 'snmpv2c',
   -community => 'private'
);

if (!defined $session) {
   printf "ERROR: %s.\n", $error;
   exit 1;
}

my $result = $session->get_request(-varbindlist => [ $OID ],);
#my $result = $session->get_bulk_request(-varbindlist => [ $OID ],);

if (!defined $result) {
   printf "ERROR: %s.\n", $session->error();
   $session->close();
   exit 1;
}

print "$result->{$OID}\n";

foreach my $key ( sort keys %$result ) {
    print "$key => $$result{$key}\n";
}

$session->close();
