The server experiences an error return code from TCP/IP while sending data over the indicated socket. This may be a normal event if either side of the connection is abruptly ended.
The session is ended. Server operation continues.
If the session is ended as a result of intentionally stopping either the client or server, no response is required. Otherwise, ensure that the client and server can communicate through such means as Telnet or FTP applications, which are part of the TCP/IP suite.
