Chapter 7 Controlling Network Discovery Click Start, and then click Control Panel. Click Network And Internet, and then click Network And Sharing Center. In the Sharing And Discovery section, click the down arrow to expand the Network Discovery option.

Chapter 7 Controlling Network Discovery (cont.) Click the appropriate radio button to turn Network Discovery on or off. Click Apply. After confirming that you are making the change, the Network Discovery status indicator changes to reflect the new state. Close the Network And Sharing Center.

Chapter 7 Controlling Sharing File sharing Public folder sharing Printer sharing Media sharing

Chapter 7 Changing the Network Location Open the Network And Sharing Center. In the network details section, click Customize.

Chapter 7 Changing the Network Location (cont.) After you confirm that you are making the change, click the appropriate radio button to select the network Location Type and click Next. Click Close. Close the Network And Sharing Center.

Chapter 7 Displaying a Network Map Network Discovery must be turned on. If the computer is a member of a Windows domain, group policy must be configured to permit network mapping. Any Windows XP computers on the network must have the LLTD Responder software installed.

Chapter 7 Viewing Connection Status Click Start, and then click Control Panel. Click Network And Internet, and then click Network And Sharing Center. In the network details section, click View Status. Click Details.

Chapter 7 Manually Configuring TCP/IP Click Start, and then click Control Panel. Click Network And Internet, and then click Network And Sharing Center. Click Manage Network Connections. Right-click the connection you want to manage and, from the context menu, select Properties.

Chapter 7 Select Internet Protocol Version 4 (TCP/IPv4) and click Properties. Click the Use The Following IP Address radio button and enter appropriate values. Manually Configuring TCP/IP (cont.)

Chapter 7 Click Start, and then click Control Panel. Click Network And Internet, and then click Network And Sharing Center. Click Set Up A Connection Or Network. Click Set Up A Dial-up Connection, and then click Next. Creating a New Network Connection

Chapter 7 Enter the Dial-up Phone Number, User Name, and Password supplied by your ISP. Click Connect. If the attempt succeeds, the connection is established and communication with the ISP commences. If the connection attempt does not succeed, The Internet Connectivity Test Was Unsuccessful page appears. Creating a New Network Connection (cont.)

Chapter 7 To create the dial-up connection without actually connecting to the ISP, click Set Up The Connection Anyway. Click Close. Creating a New Network Connection (cont.)

Chapter 7 Using TCP/IP Tools Ipconfig.exe Ping.exe Tracert.exe Nslookup.exe

Chapter 7 You Learned The networking stack used on Windows Vista computers corresponds roughly to the seven- layer OSI reference model. The Open Systems Interconnection (OSI) reference model consists of seven layers: physical, data-link, network, transport, session, presentation, and application.

Chapter 7 You Learned (cont.) Ethernet, the data-link layer protocol used on most LANs, consists of physical layer specifications, a frame format, and a MAC mechanism. The network and transport layer protocols work together to provide an end-to-end communication service that achieves the quality of service required by the application requesting network services.

Chapter 7 You Learned (cont.) The functions of the session, presentation, and application layers are often combined into a single application layer protocol. Windows Vista includes support for both the IPv4 and IPv6 protocols.

Chapter 7 You Learned (cont.) Network Discovery is a Windows Vista feature that simplifies the task of firewall configuration by enabling you to block or allow the protocols and ports needed for the computer to browse and access the network. The Network Map utility uses the Link Layer Discovery Protocol (LLTD) to detect network devices and connections.

Chapter 7 You Learned (cont.) Most networks use DHCP to configure their TCP/IP clients, but it is still possible to configure them manually. Windows Vista includes a variety of command line TCP/IP tools including Ipconfig.exe, Ping.exe, Tracert.exe, and Nslookup.exe.
