SYMPTOMS
When you use the WSAAccept condition function to decide whether to accept,
reject, or defer an incoming connection, you must set QOS on the socket if
lpSQos is not NULL. Otherwise, WSAAccept fails with error 11014 -
WSA_QOS_TRAFFIC_CTRL_ERROR. Also, dereferencing lpSQos does not reveal
valid data for setting QOS. Therefore, you should not use the contents of
lpSQos.
RESOLUTION
To work around this problem, set QOS on the socket in the condition
function using the WSAIoctl API with the SIO_SET_QOS function code and pass
in a valid QOS structure. Please note that you must do this even if the
socket was already made into a QOS socket prior to calling WSAAccept using
SIO_SET_QOS.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed
