WSAIoctl (SIO_SET_QOS) Returns SUCCESS When It Should Return FAIL

This article has been archived. It is offered "as is" and will no longer be updated.
When a computer is multihomed or if multiple addresses are assigned to an interface, when you try to add a flow, the operation is unsuccessful. Also, SET_QOS does not return an error when the flow specification exceeds the interface capabilities.
This problem occurs if resource reservation protocol (RSVP) is not managing routing information correctly when the computer is multihomed or when multiple addresses are assigned to an interface. Also, RSVP is not propagating the error information between the service and the API correctly.
