Transcript Configuring a Network Adapter

Chapter 8: Configuring
Network Connectivity
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

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– Outdated network card driver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)

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

Sharing and Discovery
• Network Discovery
• File Sharing
– Three folders shared by default:
• Public
• Users
• Printers

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

Network

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)

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)

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
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
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
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
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

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
