BASIC NETWORK REQUIREMENT FOR
OFFICE NETWORKING
Small Office Network
• Networking PCs, for sharing resources comes
into anybody’s mind who owns more than one
computer.
• But, the emphasis here is on the most practical
and cost effective way of doing it.
• Hence, why not connect the PCs to form a LAN?
A network let’s you share files, directory, drives
and peripherals which is not only convenient but
economical as well.
Setup required for small office network
• Components required for such an office LAN are
Network Interface Cards (NICs), UTP cables,
Switch/Hub and last but not the least the right operating
systems.
The Configurations
•
This involves connecting your PCs together using
UTP cables and the hub/switch; installing the operating
system and necessary drivers, and enabling the sharing
features of your network. Having inserted your network
card and installed the drivers, connect your PCs to the
central hub/switch.
•
To directly connect two PCs, special crossover UTP
cables are required. Once your connections are up, you
need to perform several configurations for sharing files,
printers etc. with other machines.
Installing protocols
• Suppose we had Window 98 installed on each machine.
Protocols imply formats and procedures for data transfer.
Window 98 has the TCP/IP protocol by default.
• To add new protocols, go to Network Neighborhood>
Properties.
• Click on Add>Protocols>Microsoft. A list of protocols
are displayed, from which you can choose the required
protocols.
• You will be prompted to insert Win 98 CD to copy the
relevant files.
• For small networks, you will require the NetBEUI
protocol. Select TCP/IP properties and specify a static
IP address to the machine.
Enabling File and Printer Sharing
• For file and printer sharing, go to Network
Neighborhood>Properties>File and Printer
Sharing for Microsoft Networks.
• In the File and Printer Sharing dialogue box,
• Enable the two options of
give others access to my files and
allow others to print to my Printer(s).
Sharing Folders
• You can specify specific drives and
directories to be shared with other
computers in LAN.
• Right click on the particular drive or
directory and click on sharing.
• You can share individual directories or
entire drives with specific access rights.
• You can provide them with a read only
access or access through password.
Sharing printers
•
•
•
•
•
Connect the printer to any machine on the
network and install the required drivers.
Go to Control Panel>Printer.
Right click on the name of the printer, select
sharing and give it a shared name.
To access it from anywhere in the network,
Go to Setting>Add and follow the Add printer
wizard.
Increasing connection speed (Win XP)
• Some of us may find that after installing
Windows XP, the Internet connection get
slower.
• A possible reason for this is the QOS
(Quality of Service) installed.
• This service reserves 20 per cent of the
bandwidth for itself, even with QOS
disabled.
How to remove QOS Reserved Quota
• In order to remove this reserved quota, you will have to
make sure you are logged on as Administrative.
• Go to Start>Run and type gpedit.msc
• Expand the ‘local computer policy’ branch, the
‘administrative templates’ branch, and the ‘network’
branch.
• Highlight the ‘QOS Packet Scheduler’ in the left window
double-click the ‘limit reservable bandwidth’ setting.
• Then on the Setting tab, check the ‘enabled’ item and
change the ‘Bandwidth limit %’ to read 0.
After doing this, you should immediately notice a boost in
your Internet connection speed.
