Objective 6.1 Configure and Troubleshoot the TCP/IP Protocol<br />

Objective 6.1<br />

Configure and Troubleshoot the<br />

TCP/IP Protocol<br />

26-7<br />

For two computers to communicate, they must agree to speak a common language. On<br />

the Internet, and most private networks, this common language is TCP/IP. Each device<br />

on a TCP/IP network is assigned one or more unique IP addresses. You can assign IP<br />

addresses in three ways: DHCP, Automatic Private IP Addressing (APIPA), or manually.<br />

Both DHCP and APIPA are enabled by default.<br />

If a computer cannot communicate with another computer on the network, you must<br />

verify that the network adapter is installed and operational in Device Manager. Next,<br />

verify that it is physically connected to the network. Then run protocol-specific utilities<br />

designed to test network connections. Some of the tools for testing TCP/IP connectivity<br />

included with Windows XP Professional are Arp.exe, Hostname.exe, Ping.exe, Pathping.exe,<br />

Tracert.exe, Netstat.exe, Route.exe, and Ipconfig.exe.<br />

To successfully answer questions in this objective, you must know how to install, configure,<br />

manage, and troubleshoot network adapters. You also need to know how to<br />

install, configure, manage, and troubleshoot TCP/IP connections.
