Summary
MODULE 1
Client Configuration Basics
Client Configuration Overview
• Client configuration is a two step process
• Step 1: Facilitate general network address– Internet access
• Step 2: Facilitate specific network address– Microsoft or other network address
General Network Access
• Install NIC, drivers, TCP/IP etc.• Test for access• Access the Internet
Specific Network Address
• Give the computer a name• Enter the computer in a domain or a
workgroup– Domain name applies to client server
networks– Workgroup name applies to peer-to-peer
networks
• Access one or more specific networks
Components to be Configured
• Step 1: General network access– NIC– Client for a particular network– Protocol – Services
• Step 2: Specific network access– Computer ID– Define Workgroup or Domain
Components to be Configure for General Access
• NIC• Protocol and properties• Client for a Network
– Microsoft or Novell for example
• Network services– File and print sharing, if desired
End of Module 1
Module 2
NIC Configuration
NIC Configuration
• Install the adapter• When an OS such as Windows XP is
installed the NIC will automatically be installed
• Install the latest driver for the adapter– The latest driver for a particular
operating system is usually obtained from the NIC manufacturers website
NIC Functioning
• Check for proper functioning of the NIC by going through the device manager– There should not be a yellow exclamation
mark next to the NIC
• Most problems can be solved by installing the correct driver
• Driver installation could be done by invoking an installation wizard
Checking for Functioning of NIC
• Go through the device manager to check for proper functioning of the NIC
Correcting Problems
• In the previous slide there was no yellow exclamation mark against the NIC– Therefore, the NIC is properly functioning
• If there was a yellow exclamation mark, then, in most instances, then the NIC is not functioning properly– Most problems could be solved by installing
the correct driver or updating the driver for NIC
Installing or Updating the Driver
• There are different ways of accessing the properties of the NIC to update the driver– One is to access the properties from the device
manger listed in the Computer Management Console that was shown before
– The other is to access the properties from either the control panel or from the network neighborhood icon
• Updating will be discussed under a different module
Multiple Adapter
• In general, there would be only one NIC in the computer
• It is also possible to have multiple adapters in a computer – A protocol can be bound to each
adapter– The protocol could be different in
each case
Reasons for Multiple Adapters
• Use the computer as a router• Host multiple virtual websites on a
single server with each IP address assigned to each NIC being referenced by a particular domain name

Module 4
A Preview of Major LAN Protocols
Major Protocols
• TCP/IP– De facto protocols of the Internet
• IPX/SPX– Used in Novell networks
• NetBEUI– A non routable local protocol
NetBEUI
• Supported by – Windows 9X, Windows NT, Windows
2000 and Windows XP • Non-routable protocol used for
setting a local LAN that does not require Internet access
• Can be used for an internal peer-to-peer or client-server network
IPX/SPX Compatible Protocol
• Used in Novell networks • Required for interoperability of
Windows network with Novell networks
• Routable protocol• IPX/SPX can be used for peer-to-
peer or client-server networking
TCP/IP
• An important protocol used widely on the Internet
• A routable protocol • Supports communication with UNIX
networks or any other network that work under the TCP/IP protocol– The base protocol in UNIX networks is
TCP/IP• Can be used for configuring peer-to-
peer as well as client-server networks of very large scale

Module 5
Basic TCP/IP Installation and Configuration
TCP/IP Installation and Configuration
• A two-step process• First, install the protocol
– With many modern OSs such as Windows XP, it is automatically installed
• Second, configure its properties– When TCP/IP is automatically installed, the
properties are set to be obtained from a DHCP server
– However, it is also possible to manually set the properties

Accessing the Window for TCP/IP Properties
• Under different Windows operating systems the TCP/IP properties are accessed in different ways – The best and the most consistent way to
access TCP/IP properties Windows is to go through the Control Panel and then select the Network Icon
– Another way to access the properties is to go through Network Neighborhood
– Thereafter, select the network properties (Based on the NIC) and then then continue to select the TCP/IP properties

TCP/IP Configuration Options
• Dynamic IP– A DHCP server must be present in the
network to issue dynamic IP– In a number of cases, the MAC address of
the client is registered to prevent unauthorized leasing of IP addresses to clients
• Static IP – Obtain the IP address specifications from
the network administrator
DHCP and TCP/IP Configuration
• Without a DHCP server– Requires the static assignment of IP
addresses and properties– The DHCP server need not reside on the
same subnet
• With a DHCP server– IP addresses etc. are automatically assigned
by the DHCP server– Select the appropriate option for the TCP/IP
address to be dynamically assigned by the DHCP server

AdvancedTCP/IPProperties
IPAddress
Assignment of Properties for TCP/IP
• IP address• Subnet mask• Gateway address• DNS address
– Preferred– Alternate, if available
Alternate IP
• If the computer is used on another network as well, an alternate IP address may also be set– It can be a private IP address– Or, it could well be a static IP address
that is manually set
IP Addresses for Restricted Internal LANs
• For an internal network, only the IP addresses and the subnet masks need to be assigned– Note that subnet mask is not an IP address
• Such networks will not have access to the outside world meaning that it would not have a connection to the Internet
• There are also some IP addresses reserved for internal use that are known as private addresses– An example is 192.168.0.1
Facilitating External Access
• A gateway address is required to facilitate external address
• A gateway is generally a router that directs the traffic to the next segment of the network that would eventually be linked through a series of hops over network segment to its destination
• There can be more than one gateway present in a network meaning that multiple gateway addresses can be entered in the TCP/IP properties window

Advanced TCP/IP Settings
Accessing Advanced Properties
• Advanced properties can be accessed from the tab marked advanced
Advanced Properties of TCP/IP
• IP settings• DNS• WINS• Options
– Security related
IP and Gateway Settings
• Multiple IP addresses for the same NIC
• Multiple gateways
DNS
• Multiple DNSs• Search suffix order• Registering current computer with
the DNS server
WINS
• Setting multiple WINSs• Add LMHOST lookup• Set NetBIOS over TCP/IP to cater
for older applications that rely on NetBIOS
More on WINS
• WINS Configuration– This can be configured if there is a
WINS server on the network– The purpose of the WINS server is to
resolve Windows client names into IP addresses
– Windows names are not common in today’s environment as all computer names are based on TCP/IP
Options
• Set TCP/IP filtering by limiting access to certain ports for certain protocols
TCP/IP Implementation and Configuration End
Result
• The workstation is ready for Internet access
• Tasks possible– Access Internet
• Note: The computer may have a name generated by the OS such as Windows XP
End of Module 6
Module 7
Network Client Service
Network Components
• NIC drivers– Load the correct drivers
• Protocol– Install the TCP/IP protocol
• Client• Services
Client Installation
• When TCP/IP is installed, the Client for Microsoft Networks is automatically installed
• In the following example, the Client for Novell Netware will be installed so that this computer may also access Novell networks
Installed Components
• The previous process will install the client service for Netware
• It will also install the required protocols to access Novell network– NWLink related protocols
Uninstalling Client Services
• The client services for Novell Netware can be uninstalled as well
End of Module 7
Module 8
Network Services
Services
• There are many services that could be installed
• To share files and printers, the file and printer sharing service must be installed– An example will be presented later
showing the installation of the file and printer sharing service
Some Examples of Services
• File and printer sharing– Microsoft networks
• Backup of data• HP Laser Jet administration
Backup Data
Install the Arcada Backup Agent, for example
Client Backup Tape
Network Printer Administration
• A network attached printer directly connected to a network can be administered from a client by installing the administration service on the client
Remote HP LaserJet Administration

LaserJet connecteddirectly to the network.
Client Station HP LaserJet
Installing File and Printer Sharing Services
• In most cases, when a network is installed by the OS, file and printer sharing services are automatically installed
• If these services are not required, for security, they should be disabled
• The following example shows the installation of the said services based on the assumption that they were not installed
End of Module 8
Module 9
Joining a Network
Logon
• Local use does not require the client to be connected to a network
• Network Access– Joint a Workgroup for peer-to-peer
networking– Join a Domain for client-server
networking• Active Directory• Non-Active Directory
To Join a Network
• The computer must have a name– When the OS is installed, it will automatically
generate a name for the computer– The generated name can be, and often is,
changed
• It must be entered into a network• The following slides illustrate the process
of changing the computer name to Nanda1 and entering the computer into a workgroup network known as GANESAN
Summary of Major Networking Components
• Adapter• Client• Protocol• Services• Client Identification• Joining a network
End of Module 9
END OF CHAPTEREND OF CHAPTER
Installation of Other Components
• When a protocol is installed other components such as the Client option may be installed
• In certain case, the File and Print sharing service may also be installed– This service must be activated to allow
files and printers to be shared by others in the network
