SYMPTOMS
In Windows Vista, a Winsock connection may fail when the program that opens the connection calls the Setsockopt function.



CAUSE
This problem occurs when the program uses the Transport Data Interface (TDI) filter drivers. This problem occurs because TDI filter drivers are supported on Windows Vista by a compatibility layer called TDX. If the connection has been disconnected by the time the Setsockopt function is called, TDX causes the function to return a value of WSAECONNRESET.

In earlier operating systems, the call to the Setsockopt function succeeded.
