Guide to MCSE 70-270, Second Edition, Enhanced 1

Windows XP Network Overview

• Most versatile Windows operating system• Supports local area network (LAN) connections• Supports emerging wireless technologies• Improved on the remote access support found in

previous versions• Can function as:

• Client

• Server (limited)

• Both


Windows XP Network Overview (continued)

• Can function as:• Client

• Server (limited)

• Both

• Networking components can be added and removed


TCP/IP

• All-embracing suite of protocols• Covers a wide range of capabilities• Been around for a long time• Most common networking protocol• Used by the Internet


TCP/IP Advantages

• Supports networking services better than the other Windows XP protocols

• Multiple routing protocols• Good error detection and handling• Works with most kinds of computers


TCP/IP Disadvantages

• Not fast• Not easy to use• Requires

• Fair degree of expertise

• Careful planning

• Constant maintenance and attention

• Mass of information and detail work


Networking Under Windows XP

• Controlled by a single multifaceted interface that combines networking access for:• LAN

• Internet

• Modem


Wireless Networking

• Supports IEEE 802.11 wireless standards• Also known as Wi-Fi networks• Base station

• Supports one or more clients

• NIC• Client must have wireless NIC


The Windows XP Network Bridge

• Layer 2 bridge between two or more network interfaces

• Connects network segments• No need to purchase separate bridge or router• Only single bridge per system supported• Only similar interfaces can be bridged


Network Setup Wizard

• Used to configure nondomain networks• Used for small offices and home networks• Step-by-step, walk-through tool• Can be opened from the network tasks list• Wizard on the system to be the ICS host first


Managing Bindings

• Binding• Order in which Windows XP networking components

are linked

• Affect how the systems behave• Affects system performance• Default behavior:

• Binds any two components that share a common boundary layer

• Known as complete binding


Advanced Settings dialog box, Adapters and Bindings tab


TCP/IP Architecture

• Suite of protocols• Internet Protocol

• Provides source and destination addressing and routing

• Addresses• 4 bytes (32 bits) long

• Each octet between 0 and 255

• Connectionless datagram protocol

• Fast but unreliable


IP Addresses

• Designates network and host• Divided into Classes• Subnet mask:

• Used to block network part of address


TCP/IP Protocols

• Internet Control Message Protocol (ICMP)• Address Resolution Protocol (ARP)• Dynamic Host Configuration Protocol (DHCP)• Transmission Control Protocol (TCP)

• Primary Internet transport protocol

• Connection oriented

• Port number• Identifies process


TCP/IP Protocols (continued)

• User Datagram Protocol (UDP)• File Transfer Protocol (FTP)• Telnet• Simple Mail Transfer Protocol (SMTP)• Simple Network Management Protocol (SNMP)


TCP/IP Utilities and Services

• Berkeley R Utilities• route command• tracert (or trace route) command• Packet Internet Groper (PING)• Trivial File Transfer Protocol (TFTP)• Domain Name System (DNS)• Windows Internet Naming Service (WINS)


TCP/IP Utilities and Services (continued)

• IPCONFIG• NETSTAT• NBTSTAT


TCP/IP Configuration

• Performed through the Network Connections tool• Default settings:

• Seek out DHCP server to provide all configuration settings

• Alternate configuration tab• Used when DHCP is not available


Windows XP Remote Tools

• Remote Assistance• Allows a distant user to view your desktop

• Have control over the mouse and keyboard activities

• Remote Desktop• Enables you to access your client’s logon environment

from a remote system


Remote Assistance

• Designed to simplify the task of training users• Requires invitation

• Invitation expires

• Both machines must be XP• Windows Messenger or MAPI-compliant e-mail

utility required• Uses Remote Desktop Protocol (RDP)


Remote Desktop

• Similar to a single client version of Terminal Services

• Workers access work machine from home• Enabled through a component of IIS


Workstation Service

• Supports client access to network resources • Handles functions such as:

• Logging in

• Connecting to network shares (directories and printers)

• Creating links using Windows XP IPC options

• Elements:• User mode interface

• Redirector


Server Service

• Handles the creation and management of shared resources

• Performs security checks against requests for such resources

• Elements:• Server.exe

• Srv.sys


Multiple Universal Naming Convention Provider

• Defines link between applications that make UNC requests for different redirectors

• Allows applications to remain oblivious to number or type of redirectors that might be in use

• Chooses redirectors on basis of highest registered response time


Universal Naming Convention Names

• Represent the format used in NetBIOS-oriented name resolution systems

• Example: \\computername\sharename\dir-path\filename.ext
