An unrecognized object was found in the QoS provider-specific buffer. WSA_QOS_RECEIVERS 11005 QoS receivers. The name is not an official host name or alias, or it cannot be found in the database(s) being queried. An invalid value was given for one of the arguments to a function.
Socket Error 10054
When a particular Windows Sockets function indicates an error has occurred, this function should be called immediately to retrieve the extended error code for the failing function call. The ICMP message means that a router can't forward the IP datagram, possibly because it didn't get a response to the ARP request (which might mean the destination host is down). The application has tried to determine the status of an overlapped operation which is not yet completed. A call to the WSALookupServiceEnd function was made while this call was still processing.

WinSock description: The current WinSock implementation does not support the Windows Sockets specification version requested by the application. WSAEFAULT 10014 Bad address. If there is more than one Winsock DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded. Developer suggestions: to make your application more portable: with datagram sockets don't use connect() and sendto() on the same datagram socket in an application, and always "disconnect" before calling connect() more
The behavior may vary: some WinSocks might complete in background, and others may require another call to closesocket to complete. Wsagetlasterror 0 WinSock description: Similar to Berkeley & Microsoft C, the generic meaning is that an application passed invalid input parameter in a function call. An MX record is returned but no A record—indicating the host itself exists, but is not directly reachable.

The cause of Wsatry_again error code? TCP, UDP, ICMP, ARP, DNS) that typically causes the error. Socket Error 10054 WSA_QOS_POLICY_FAILURE 11011 QoS policy failure. Socket Error 10053 This is usually caused by one or more of the function pointers being NULL.
Detailed description: There's at least one WinSock implementation that will occasionally fail a function and report this as the error value, even though the function succeeded. WinSock description: No equivalent WinSock functions:
Returned when a system call that should never fail does fail. A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram was smaller than the Commercial license available from the Doc-O-Matic site. WSAHOST_NOT_FOUND 11001 Host not found.

For instance, if the length of an argument, which is a sockaddr structure, is smaller than the sizeof(sockaddr).
User suggestions: Do you have the WinSock DLL that supports the version of the WinSock specification required by the application? This is what occurs in Berkeley Sockets. Berkeley description: An operation was attempted on something that is not a socket. Socket Error 11004 WSAEADDRNOTAVAIL 10049 Cannot assign requested address.
WinSock description: Almost same as Berkeley. This can help you (or your support staff) to zero-in on what's wrong when your application runs into a problem.

If this tends to occur after running certain applications for a while, it might be a symptom of an application that doesn't return system resources (like memory) properly.
This error occurs when the sin_port value is zero in a sockaddr_in structure for connect() or sendto(). Berkeley description: The protocol has not been configured into the system, or no implementation for it exists. User suggestions: Check that the WINSOCK.DLL file is in the current path Check that the WINSOCK.DLL file is from the same vendor as your underlying protocol stack.
