Incorrect source IP address is returned in the SNMP response in Windows 8, Windows Server 2012, Windows 7, Windows Server 2008 R2, Windows Vista, and Windows Server 2008

Symptoms

Consider the following scenario:

  • You have the Simple Network Management Protocol (SNMP) service installed on a computer that is running Windows 8, Windows Server 2012, Windows 7, Windows Server 2008 R2, Windows Vista, or Windows Server 2008.

  • The computer has a network adapter that has multiple IP version 4 (IPv4) addresses assigned.

  • An SNMP request is sent to one of the IPv4 addresses on the computer.

In this scenario, the source IP address that is in the SNMP response is not the same IP address that received the SNMP request. More specifically, the source IP address is replaced by a random IP address on the computer.

Note This issue makes SNMP monitoring unreliable on the computer that has multiple IP addresses. 

Cause

This issue occurs because SNMP does not use the control data when the WSARecvMsg function is called while sending back the SNMP response.

For more information about the WSARecvMsg function and the control data, go to the following Microsoft website:

General information about the WSARecvMsg function
