| Troubleshooting
Your Network (Part 1) |
|
In
this edition, I will be talking about a very important issue
with emphasis on how to diagnose and fix most of your network
problems. These problems constitute two parts; the Hardware
and Software aspects.
I will be pointing out some network issues and what one needs
to look out for when they arise. In this particular edition,
I will be looking at the Hardware aspect of the problems.
Processor Fan
A processor fan is supposed to blow away the heat generated
by the processor through the processor heat-sink which in
turn reduces the processor temperature from overheating. The
effect of a non-working fan will cause the system in question
not to be browsing other systems in the workgroup or domain.
It also impedes data flow within the system.
Bad Memory Module
A bad memory module will cause your system to be hanging and
unstable. This affects your system behaviour within the network.
The memory should be checked for replacement.
Faulty Switch

One or more
dead Ethernet port can also affect the system or network
device connected to it. In this case you can try another
reserve port.
In a more severe case it might be a general fault in
the switch causing network flow to be erratic and unstable.
If such case arise, I advice you to change the Switch
or Router as the case may be. Many Engineers take this
for granted.
A Bad Network Card
A situation where the entire network seems unstable,
systems on the network should be connected one after
the other in order to isolate the one causing the problem.
A network card can appear disabled sometimes causing
the computer on which it is installed to be cut-off
from the |

|
|
network.
Try and enable it. If it keeps showing disabled, try and replace
the card. If the card is onboard, make sure you disable it from
the BIOS Setup Program and then install another card.
Vibrating Hard Disk
A vibrating hard disk is a sign that the hard disk is about
to fail. It causes data access in the system to be slow. It
introduces noise thereby impeding data traffic to and fro the
system within the network. Make sure you have it replaced as
soon as possible.
Faulty
Power Supply Fan
It affects network traffic to and fro the system. Its effect
may not be noticed immediately. It gets worse as the system
stays on for a longer period. Get the power supply unit replaced.
Partial Electrical Contacts
Partial contact as regard the connection between the electrical
sockets with most of the electrical plugs of devices like your
switches, routers, etc., should be firm. Electrical spikes from
those contacts introduce distortion in the flow of data through
those devices thereby impeding on your network.
I will be concluding on this issue in the next edition. I will
then tell you some software issues too that affect your network
which you should look out for. |
