SYMPTOMS
A Winsock application may to fail to bind to a remote port on a Proxy Server computer when the Winsock application is running on the Winsock client and a remote bind is specified in the Wspcfg.ini file.



CAUSE
The entry of ServerBindTCPPorts in the Wspcfg.ini file allows a Winsock application to bind to the local ports and to the specified port on the Proxy Server computer. A call to Bind with INADDR_ANY means that the Winsock application will accept incoming requests on any local interface and send requests on the "most appropriate" local interface.

When a Winsock application is running on the Microsoft Winsock Proxy client and the Winsock application calls the Winsock function Bind with 0.0.0.0 or INADDR_ANY, the call fails and returns an error to the Winsock application. If the application specifies the local address in the Bind call, the call succeeds.
