Hello everyone, Happy New Year.
This is my first post so please be gentle!
I have been using MRTG to monitor my WAN traffic for 4 months without any issues. What a great tool!  Now i want to use it to graph CPU and (eventually) disk access times on my WIN2K servers.  I have been reading as much information as i can find on the web but i always come back to the same error messages:  
WARNING: Skipping Update of localhost.processorload, outlast is not defined
WARNING: Skipping Update of localhost.processorload, inlast is not defined
ERROR: Target[localhost.processorload][_OUT_] ' $$target[0]{$mode} ' did not eval into defined data.
ERROR: Target[localhost.processorload][_IN_] ' $$target[0]{$mode} ' did not eval into defined data.
WARNING: skipping because at least the query for . on  localhost did not succeed.

                    backoff: 1).
I used a small program called snmputilg.exe to get the relevant OID's, and here is my config file:

For the moment i am trying to get it working on the localhost, but it fails the same way on other servers.  SNMP is running in all cases. 
Please help, i have been banging my head on this for a week.
