WINSOCK Error: Protocol not supported.

Explanation:

The protocol has not been configured on the system, or no implementation for it exists. For example, if a WinSock implementation does not support SOCK_RAW with IPPROTO_IP (or any other protocol), then the socket() call would fail with WSAEPROTONOSUPPORT. (However, if it does not support SOCK_RAW at all, you should expect WSAESOCKTNOSUPPORT).An incompatible protocol has been selected for establishing the connection.

User Action:

Developer suggestion: If you are trying to use an optional feature, handle the request as a non-fatal error (if possible), since some WinSock calls can legally fail the request. User suggestion: Try again, using a different protocol. If you are using a third-party Transmission Control Protocol/Internet Protocol (TCP/IP), verify that it is compatible with Wsock32.dll. If you are using Microsoft TCP/IP, remove and reinstall TCP/IP. Or use another protocol that is compatible with Wsock32.dll.
