Node Sub-Agent on Windows

I'm using the node net-snmp package  to create a simple subagent but I cannot query its only table provider (Error in packet... No such variable name in MIB).  I have installed net-snmp and registered it, I am able to  query simple things such as uptime:
C:\usr\etc\snmp>snmpwalk -v1 -c public 127.0.0.1  .1.3.6.1.2.1.1.3
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (306196) 0:51:01.96

So, at least I know the snmpd is running and responding.
My snmpd.conf:rwcommunity  public  
master agentx
agentXSocket tcp:localhost:705load  12 12 12
Any thoughts would be greatly appreciated.
thanksIan in Ottawa
