Software diagnostics test the higher-level functions of the NIC, such as network communication with other stations. These programs typically consist of a sender and receiver portion. Each portion is run on one of a pair of computers connected to the network. The sender sends a test packet out to the receiver, and when the receiver receives the packet, it immediately sends a response. This function is similar to the TCP/IP Ping command, but is protocol-independent.

Workstation Configuration

In addition to knowing how to configure a station’s hardware, you must also be able to configure a Windows 9x or 2000 workstation to connect to the different types of NOSes that might be on your network. For the Network+ exam, you should be able to configure these workstations to connect to the following operating systems:

■ Windows NT/2000 servers

■ NetWare

■    Unix/Linux

■    Macintosh

The process for configuring Windows to connect to these various operating systems is basically the same for all server OSes (only the workstation software component differs very slightly), so we’ll just cover the two most popular client operating systems’ network configurations.

Configuring a Windows 9x Network

The configuration of a Windows 9x network centers on the Control Panel’s Network program. From this one interface, you can configure client software, protocols, NICs, and the network services you want this machine to perform. To access the Network program, select Start > Settings > Control Panel and double-click Network in the Control Panel window that appears. Windows 9x will display the Network window. The Network window has three areas of interest: the Components list, the Primary Logon list, and the File and Printer Sharing button.
