SYMPTOMS
A program that is running in Windows 2000 that uses the SnmpMgrGetTrapEx function to receive Simple Network Management Protocol (SNMP) traps may not appear to be receiving them.
CAUSE
The SnmpMgrGetTrapEx function is defined as follows:
SnmpMgrGetTrapEx(
AsnObjectIdentifier * pEnterpriseOID,
AsnNetworkAddress * pAgentAddress,
AsnNetworkAddress * pSourceAddress,
AsnInteger * pGenericTrap,
AsnInteger * pSpecificTrap,
AsnOctetString * pCommunity,
AsnTimeticks * pTimeStamp,
SnmpVarBindList * pVarBindList);
Two of these parameters (pAgentAddress and pSourceAddress) are not being returned correctly in Windows 2000. pAgentAddress should return the IP address of the SNMP agent as listed in the SNMP Trap PDU, but is instead returning the IP endpoint. pSourceAddress should return the address of the IP endpoint that actually sent the trap, but is instead returning a null address.
Because of this, a program that calls this function discards any traps, making it appear that they where never received.
Two programs known to be affected by this problem are Compaq Insight Manager CIM 32 and Insight XE.
