Question : MRTG on 2003 Server

Ok, first, I admit it - I've never really experimented with SNMP, so while I understand the BASIC concept that it's "Simple Network Management Protocol" I don't really understand all that much more about it or how to use it.

Now, I'm trying to setup MRTG on a 2003 server that is also acting as a router with a public interface and a private interface.  My MRTG config file looks like this:
-----------------8<------------------------
# Created by
# cfgmaker [email protected] --global "WorkDir: c:\inetpub\wwwroot\mrtg" --output mrtg.cfg

### Global Config Options

#  for UNIX
# WorkDir: /home/http/mrtg

#  or for NT
# WorkDir: c:\mrtgdata

### Global Defaults

#  to get bits instead of bytes and graphs growing to the right
# Options[_]: growright, bits

EnableIPv6: no

-----------------8<------------------------
PLEASE NOTE: - The IP Address used is NOT the actual one I have in the config

Also, I have named the community (or so I believe) "home"
Under the Traps section of the service properties, I have set the Trap Destinations to:
127.0.0.1
192.168.1.254
225.225.64.70

I have not modified the Security tab at all from the default.

The following is what I get when I attempt to run the update manually.

C:\mrtg-2.15.0\bin>perl mrtg mrtg.cfg

 And I have seen this http://support.microsoft.com/default.aspx?scid=kb;en-us;323340 but it doesn't tell you what to do if the it fails (great isn't it?)
Here's what I get when I attempt to verify as per the above KB:
C:\mrtg-2.15.0\bin>snmputil getnext servername home .1.3

C:\mrtg-2.15.0\bin>snmputil getnext 192.168.1.254 home .1.3
