TCP/IP, like any other networking protocol, requires configuration before data can be sent across a network successfully. All protocol configuration, including TCP/IP, is done through the Network section of Control Panel.

1. Within Network, highlight TCP/IP (bound to the Ethernet card) and click Properties.

  TCP/IP Configuration: TCP/IP Properties

2. After clicking the TCP/IP Properties button, the TCP/IP Properties menu will appear with the IP Address tab selected as in the image above.
3. Select the radio box labeled 'Specify an IP address'. The IP Address and Subnet Mask fields will become available.
4. For private local area networks, the IP address range 192.168.0.x should be used where 'X' ranges between 1 and 254. These IP addresses are not used anywhere else on the Internet and therefore conflicts will be avoided.
5. Enter an IP address in the IP Address field. If you are configuring the workstation running CMail Server, use 192.168.0.1. Enter a value of 255.255.255.0 in the Subnet Mask field.
6. Once both values have been entered, click on the DNS Configuration tab at the top of the menu.

Testing TCP/IP
When TCP/IP has been installed on two or more workstations, it can be tested by running a MSDOS command prompt, entering PING 192.168.0.2 followed by the return key.

If TCP/IP has been installed correctly, a ping reply like the one shown below will be displayed four times on the screen.
