SYMPTOMS

Consider the following scenario:
  • You enable the Simple Network Management Protocol (SNMP) feature for the Windows Management Instrumentation (WMI) provider on a computer that is running Windows Server 2003 in a Network Address Translation (NAT) environment.
  • The computer creates an SNMP trap notification, and then it sends the notification through a NAT router.
  • The SNMP trap notification is received by a server.
In this scenario, both the AgentAddress property and the AgentTransportAddress property are set to the IP address of the NAT router in the SnmpNotification class of the notification. Therefore, the computer that created the SNMP trap notification cannot be identified.

Note The AgentAddress property is the network address of the entity that created the notification. The AgentTransportAddress property is the network address of the entity that sent the notification.

CAUSE

This issue occurs because of an error in the SNMP WMI provider. The SNMP WMI provider incorrectly set the AgentAddress property of the SNMP trap notification.
