Under certain conditions, Microsoft Operations Manager (MOM) 2005 may stop processing incoming Simple Network Management Protocol (SNMP) traps. This generally occurs after MOM 2005 receives many SNMP traps in a short time. By restarting the MOM service (MOMService.exe), you can bring SNMP trap processing back online for a short time. However, the problem will probably occur again.
This problem occurs because MOM 2005 does not correctly handle a specific error condition that Windows Management Instrumentation (WMI) returns. This hotfix makes sure that MOM 2005 re-subscribes to the SNMP trap events with WMI after error conditions such as this occur.
