Before you can communicate over the network, TCP/IP must be started.
The server automatically starts TCP/IP for you when you start the system. However, if you end TCP/IP due to problems so that you need to manually restart TCP/IP, read the following information.
Remember that your line descriptions, network server descriptions, and network interface descriptions should be configured to vary on with TCP/IP. This allows these configuration objects to start at the same time TCP/IP starts. See Varying on communication lines, controllers and devices for more information.
