1. Chapter 8: Configuring Network Connectivity

2. Installing Network Adapters Network adapter cards connect a computer to a network. Installation –Plug and Play adapters will install automatically –Non-Plug and Play adapters must be installed with the Add Hardware Wizard in Control Panel 2/19

3. Configuring a Network Adapter Device Manager Network adapter’s Properties dialog box –General tab –Advanced tab –Driver tab –Details tab –Resources tab –Power Management tab 3/19

4. Troubleshooting Network Adapters Common causes of network adapter problems –Network adapter not on the HCL –Outdated network card driver –Network adapter card not recognized by Windows Vista –Hardware not working properly –Improperly configured network protocols –Improperly configured network card –Bad cable –Bad network connection device (hub, switch, router) 4/19

5. Network and Sharing Center 5/19

6. Network Locations Public –Used for unsecure, public networks –Does not allow discovery between networked computers Private –Used for secure, private networks –Allows discovery between networked computers 6/19

7. Sharing and Discovery Network Discovery File Sharing –Three folders shared by default: Public Users Printers Public Folder Sharing Printer Sharing Password Protected Sharing Media Sharing 7/19

8. Tasks Pane View Computers and Devices Connect to a Network Manage Wireless Networks Set Up a Connection or Network Manage Network Connections Diagnose and Repair 8/19

9. Remote Access Two methods of remote access: –Dial-in connection to a Remote Access Service (RAS) Server –Virtual Private Network (VPN) Connection 9/19

10. Remote Access over VPN Tunneling Protocols –Point-to-Point Tunneling Protocol (PPTP) –Layer Two Tunneling Protocol (L2TP) Authentication Methods –Password Authentication Protocol (PAP) –Challenge Handshake Authentication Protocol (CHAP) –Microsoft CHAP v2 (MS-CHAPv2) –Extensible Authentication Protocol (EAP) Encryption Options –Microsoft Point-to-Point Encryption (MPPE) –Internet Protocol Security (IPSec) 10/19

11. Connecting to a Wireless Network 11/19

12. Configuring Security for a Wireless Network Disable SSID broadcast Create MAC address filter Enable Encryption –Wired Equivalent Privacy (WEP) –Wi-Fi Protected Access (WPA) –WPA version 2 (WPA2) 12/19

13. Overview of TCP/IP Required for Internet connectivity Installed by default in Vista Main protocols: –Transmission Control Protocol (TCP) –Internet Protocol (IP) –User Datagram Protocol (UDP) –Address Resolution Protocol (ARP) –Internet Control Message Protocol (ICMP) –Internet Group Management Protocol (IGMP) 13/19

14. Basics of IPv4 Addressing 32-bit address Uniquely identifies your computer on the network Written in dotted decimal notation (192.168.1.144) Subnet mask –Used to specify the network portion and host portion of an address Address classes –Class A –Class B –Class C Default Gateway 14/19

15. Methods of IP Address Assignment Dynamic Host Configuration Protocol (DHCP) –Assigns IP addressing information to computers Automatic Private IP Addressing (APIPA) Static Address Configuration Alternate Configuration 15/19

16. Domain Name System (DNS) Servers Used to resolve domain names, such as www.sybex.com, to IP addresses. DNS servers maintain a distributed database of all the registered domains and their IP addresses. HOSTS files are used if DNS servers are not available. 16/19

17. Windows Internet Name Service (WINS) Servers Used to resolve NetBIOS names to IP addresses. NetBIOS names are primarily used for backwards compatibility with Windows NT 4. LMHOSTS files are used if WINS servers are not available. 17/19

18. IPv6 Addressing 128-bit addresses –Allows for a much larger address space than IPv4 Can coexist with IPv4 Written in hexadecimal format –Equivalent examples: 0123:0456:0789:0000:0000:00AB:00 CD:00EF 123:456:789:0:0:AB:CD:EF 123:456:789::AB:CD:EF 18/19

19. Testing IP Configuration ipconfig –Displays your IP configuration –Switches ipconfig /all ipconfig /release ipconfig /renew ping –Tests connectivity between two computers nbtstat –Displays NetBIOS over TCP/IP connection protocol statistics 19/19
