Network Transport Errors
[SNMP is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions. Instead, use Windows Remote Management, which is the Microsoft implementation of WS-Man.]
The Microsoft WinSNMP implementation can detect a network transport error after it transmits an SNMP message. When this occurs, the implementation sends a data receipt notification to the WinSNMP session that initiated the communication request. The implementation also returns SNMPAPI_FAILURE on the next call to the SnmpRecvMsg function for the session. The SnmpRecvMsg function fails with an extended error code that indicates a network transport layer error.
