Error Message:

Socket type not supported.

Explanation:

The support for the socket type has not been configured on the system or no implementation for it exists. You can expect this error if a Winsock implementation doesn't support socket type SOCK_RAW, for example, within the Internet address family (AF_INET).

User Action:

Handle the request as a non-fatal error (if possible), since some Winsock calls can legally fail the request.
