The server is unable to communicate by way of TCP/IP. TCP/IP has rejected a request for a socket on which the server listens.
Server operation continues, but the server cannot accept sessions from clients using the TCP/IP protocol.
Ensure that TCP/IP is operational on your system by using the ping command with your TCP/IP address as a target. If TCP/IP is not started, issue the HALT command to stop the server, and then restart the server.
