SNMP data information never comes from the MIB. A MIB is simply a static text file that allows programs to translate a data SOURCE name to a number (OID). The OID is recognized by the SNMP service on the target device. This is either directly, or with the aid of another intermediary file (such as MIB.MIB on a MS system).
Therefore, the SNMP service on the TARGET device needs to be able to decode the OID into something meaningful (such as disk % free). In your case, it does this through an extension agent called SNMP4NT, which relies upon the MS SNMP stack. That's why a sucessful and controlled install of SNMP is critical (i.e. SNMP service installed then SP6A). In many cases, the device contacting the target device does not need the SNMP service installed, but the target system ALWAYS does.

I was albe to see the OID for the drive in Getif. One question. When you run a querry with Getif, does it get the info from the server or from the MIB file that I put in the Getif subdirectory? Reason I say this is that the OID does not seem to exist on the server, as seen from the MRTG error: SNMP Error: Received SNMP response with error code error status: genErr index 1 (OID: 1.3.6.1.4.1.311.1.1.3.1.1.5.1.4) SNMPv1_Session (remote host: "xx.xx.xx.xx" [xx.xx.xx.xx].161) community: "community" request ID: 689389339 PDU bufsize: 8000 bytes timeout: 2s retries: 5 backoff: 1) at /usr/local/mrtg-2/bin/../lib/mrtg2/SNMP_util.pm line 458 SNMPGET Problem for .1.3.6.1.4.1.311.1.1.3.1.1.5.1.4 1.3.6.1.4.1.311.1.1.3.1.1.5.1.3 sysUptime sysName on [EMAIL PROTECTED] at ./mrtg line 1620 WARNING: skipping because at least the query for .1.3.6.1.4.1.311.1.1.3.1.1.5.1.4 on xx.xx.xx.xx did not succeed ERROR: Target[ciscoworks-microsoft_winnt_hdd][_IN_] ' $$target[0]{$mode} ' did not eval into defined data ERROR: Target[ciscoworks-microsoft_winnt_hdd][_OUT_] ' $$target[0]{$mode} ' did not eval into defined data WARNING: Skipping Update of ciscoworks-microsoft_winnt_hdd, inlast is not defined WARNING: Skipping Update of ciscoworks-microsoft_winnt_hdd, outlast is not defined The OID if from the Getif program.

FWIW, it worked for me once I completed those steps.
