If the hostname resolution uses a local host table, it's possible you resolved to an obsolete address. Berkeley description: A request to send data was disallowed because the socket had already been shut down with a previous shutdown() call. An application attempted an input/output network function call before establishing an association with a remote socket (i.e. WSAEISCONN (10056) Socket is already connected. http://devstude.net/socket-error/windows-socket-error-no-such-host-is-known-11001.php
Since Windows Sockets is practically a clone of Berkeley Sockets, and the rule of thumb is "when in doubt, defer to Berkeley", we can adopt the Berkeley Software Distribution error text Usually this occurs when a socket descriptor to a socket that cannot support this operation is trying to accept a connection on a datagram socket. Berkeley description: A socket operation encountered a dead network. If you get an error, it's because DNS doesn't know anything about those addresses, so a gethostbyaddr() will not be able to give you any information.

Berkeley description: This is a temporary condition and later calls to the same routine may complete normally (also known as EAGAIN error in Berkeley Software Distribution version 4.3) WinSock description: Same Berkeley description: The host you were connected to crashed and rebooted. This usually means the local software knows no route to reach the remote host.
This could be due to an out of memory error or to an internal QoS provider error. Basically, you want to identify where the problem occurred. This is a common problem. Socket Error 10054 Connection Reset By Peer This reset could be generated locally by the network system when it detects a connection failure, or it might be received from the remote host (in TCP terms, the remote host
The name you have used is not an official hostname or alias. Try this: Start > Run > Type in CMD > Press Enter > Type in PING yourdomainname.com. Returned by WSARecv and WSARecvFrom to indicate that the remote party has initiated a graceful shutdown sequence. Developer suggestions: If you have a network analyzer available, you can quickly check if the destination port number and host address are what you expect.
WSATRY_AGAIN 11002 Nonauthoritative host not found. Socket Error 11004 WinSock description: Same as Berkeley. Unlike Berkeley, however, WinSock v1.1 doesn't ascribe this error to any functions. User suggestions: Don't try running two of the same types of server applications on the same machine.
It means that there is a blocking operation outstanding. See also: These point to other errors that are similar. Socket Error 10054 Environment Novell Distributed Print Services (NDPS) Novell iPrint Situation iPrintprinter install receives Winsock error 11001 or 10061 When you try to install a printer from iPrint (default or own created map) Socket Error 10049 WSA_QOS_EUNKOWNPSOBJ 11024 Unrecognized QoS object.
Too many open sockets. 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. The "address" it refers to is the remote socket name (protocol, port and address). WinSock functions:
We suggest local configuration changes that might remedy the problem, and network and server conditions that might be the cause. Replace letter of command (control sequence) Is it correct to say "I hurt"? There are no QoS senders. An incorrect number of flow descriptors was specified in the QoS structure.
For example, this error is returned if sendto is called with the remote address of ADDR_ANY. Socket Error 11001 The requested service provider could not be loaded or initialized.

WinSock functions: accept(), listen(), recv(), recvfrom(), send(), sendto() WSAEPFNOSUPPORT (10046) Protocol family not supported. User suggestions: see WSAHOST_NOT_FOUND for details. Berkeley description: An attempt was made to access an open file (on an NFS filesystem) which is now unavailable as referenced by the file descriptor. Socket Error 10061 Connection Refused Specifically, the v1.1 Windows Sockets specification notes the domain name system (DNS) errors "FORMERR, REFUSED, and & NOTIMP.
This often happens when NIS or DNS or the hosts file is incorrect. These errors might be reported on any function that does network I/O (e.g. WSAESOCKTNOSUPPORT (10044) Socket type not supported. If you don't have the proper subnet mask, your network system may treat a local address as a remote address (so it forwards addresses on the local subnet to the router,
This error occurs when the sin_port value is zero in a sockaddr_in structure for connect() or sendto(). you tried to connect to the wrong destination host address the server application isn't running on the destination host the server application isn't listening on the right port. WinSock functions: connect(), sendto(), FD_CONNECT Additional functions: It seems odd that the v1.1 specification doesn't ascribe this error to the function bind(). Returned when a provider does not return SUCCESS and does not provide an extended error code.
First server is used' & 'Could not start session recording for server...' warnings returned at the start of a load test in Silk Performer when dynaTrace plugin is enabled 'Show TrueLog' Change the hostname in the .EFL9 license file. You cannot use more than one WinSock implementation simultaneously. Note that this error is returned by the operating system, so the error number may change in future releases of Windows.
The error can occur when the local network system aborts a connection. Any other type of operation might also return this error—for example, setsockopt setting SO_KEEPALIVE if the connection has been reset. WSAESOCKTNOSUPPORT 10044 Socket type not supported. WinSock functions: Any function that takes a socket as an input parameter: accept(), bind(), closesocket(), connect(), getpeername(), getsockname(), getsockopt(), ioctl socket(), listen(), recv(), recvfrom(), select(), send(), sendto(), setsockopt(), shutdown(), FD_CONNECT Additional
