7. Chapter 7 Understanding Network Discovery Controls Windows Firewall settings A Firewall is a barrier between the computer and the network that allows certain types of traffic through, and blocks other traffic. Firewalls filter using TCP/IP characteristics: IP addresses Protocol numbers Port numbers

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

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

11. 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.

12. 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.

14. Chapter 7 Viewing Connection Status In the Network and Sharing Centre, click View Status in the network details section.

15. Chapter 7 IPv4 Addressing IP Address - Four sets of numbers between 0 and 255 separated by a dot. Each address is unique worldwide Subnet Mask - Used for network and host identification Network identifier Host identifier Example: IP Address 142.204.34.136 Subnet Mask 255.255.0.0

16. Chapter 7 Optional Components  Gateway IP Address - router  DNS IP Address  Domain Name Service is used to translate names like www.yahoo.com into an IP Address (64.58.76.222) IPv4 Addressing

17. 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.

18. 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.)

19. Chapter 7 Uses DHCP – Dynamic Host Configuration Protocol Clients request and receive addressing information from DHCP – can be server or router Automatically Configuring TCP/IP

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

21. Chapter 7 You Learned 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.

22. 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.
