Hello Duy, This means that you have found a bug in one of Microsofts SNMP extension DLLs. You can switch from the Microsoft implementation of IP-MIB to the Net-SNMP implementation by modifying the third line of registeragent.bat as follows:
set additionaloptions= -Lf "C:/usr/log/snmpd.log" -I-winExtDLL and next to stop the Net-SNMP service, run unregisteragent.bat, run registeragent.bat and to start the Net-SNMP service again. Bart.
