SYMPTOMS

After you enable the Systems Management Server (SMS) 2.0 Event to Trap Translator Client Agent for a site that contains Microsoft Windows 2000-based client computers that are running the Simple Network Management Protocol (SNMP) service, traps that are generated by events which are configured for alerts may be sent twice to defined management stations.

CAUSE

The default Windows 2000 SNMP installation includes an Event to Trap Translation Extension Agent, which is implemented in a .dll file that is named Evntagnt.dll. The SMS 2.0 Event to Trap Translator Client Agent installs an additional extension agent that provides duplicate functionality implemented in a .dll file that is named Snmpelea.dll. Both of these DLLs monitor the Windows 2000 Event log according to the rules that are defined in the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\SNMP_EVENTS

When a configured event is written to the Event log, each extension agent generates a trap for it.

WORKAROUND

To work around this behavior, you can disable the SMS 2.0 Event to Trap Translator Client Agent for sites that include Windows 2000-based clients that are configured with SNMP.
