WSAECONNRESET
10054
	Connection reset by peer.

    An existing connection was forcibly closed by the remote host. This normally results if the peer 
application on the remote host is suddenly stopped, the host is rebooted, the host or remote network 
interface is disabled, or the remote host uses a hard close (see setsockopt for more information on the 
SO_LINGER option on the remote socket). This error may also result if a connection was broken due to 
keep-alive activity detecting a failure while one or more operations are in progress. Operations that 
were in progress fail with WSAENETRESET. Subsequent operations fail with WSAECONNRESET.
