You must set up your Windows environment for the TCP/IP network. To verify that the TCP/IP protocol is installed on your workstation, double-click Network in your Control Panel and see if TCP/IP appears in the list of network components. Double-click TCP/IP to specify your IP address and other TCP/IP properties. You have to install IPv6 protocol to make use of IBM-EEDLC (IPv6) feature.
