The Simple Network Management Protocol (SNMP) Event Log Extension Agent does not initialize correctly on a computer that is running Windows Vista with Service Pack 1 (SP1) or Windows Server 2008. Therefore, network management middleware cannot use SNMP to retrieve event log information. When this problem occurs, the following events are logged in the Application log:
