Error Message:

WINSOCK Error: Operation not supported on socket.

Explanation:

The attempted operation was not supported for the type of object referenced. Usually this occurs when a file descriptor refers to a file or socket that cannot support this operation, for example, trying to accept a connection on a datagram socket. Or the device driver for the protocol stack might not be compatible with Wsock32.dll.

User Action:

Developer suggestions: If you close a socket inadvertently in one part of an application without keeping another part notified, use socket state in an application and/or handle this error gracefully as a non-fatal error. User suggestions: 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.
