5. What’s New in Windows Vista Networking? • Network And Sharing Center • Network Map • Network Diagnostics Chapter 7

6. Using the Network And Sharing Center Task List Summary Network Map Network Details Sharing And Discovery Chapter 7

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 Chapter 7

8. Controlling Network Discovery Chapter 7

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

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

11. 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

12. 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

13. Displaying a Network Map Chapter 7

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

15. 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 Chapter 7

16. IPv4 Addressing • 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) Chapter 7

17. 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

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

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

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

21. 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. Chapter 7

22. 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. Chapter 7
