1. Network Troubleshooting:
Basic Symptoms of a network problem:
You can’t access network programs, network drives, email or the Internet.
Basic Hints of Any Troubleshooting (aka Problem Solving):
1. Clarify the problem – what is working and what is not.
2. Go from simple possible solutions to complex possible solutions – don’t
overhaul your car engine only to find out later it was out of gas or had a
bad spark plug.
3. Go sequentially through the checklist in order to isolate the problem.
4. Look for patterns that indicate associations.
Simple possibilities you can check before calling for help:
Is your computer turned on? If not, turn on both computer and monitor.
Has your computer been accessing the network or is this a new
installation? If this is a new installation, there are probably a few things that
your network guy has to setup.
Has your computer been moved recently? If it has been moved check all the
cables and also check to make sure that there is network access available (either
a jack on the wall or an available plug on a minihub).
Is your computer network cable plugged in both the computer and the
wall? (only applicable if you’re not using wireless) – If not, plug it in. If it is
plugged in, quickly unplug and plug in back in. You should hear or feel a slight
click when it is correctly in place.
Is there a light on the computer near where the network cable is plugged
in? If there is no light, and the network cable is plugged in, call your network
Are you logged in with your network password and domain name?
Sometimes people forget their passwords or the passwords have changed. Also
make sure that you have the correct spelling of everything including the domain
Have you tried restarting and logging in again? This simple action frequently
works like magic to resolve a variety of problems.
Is your caps-lock turned on? Many times the username and password
required of network access and network applications is case sensitive.
2. Has your computer given you virus warning messages? Sometimes network
problems are caused by a virus. Contact your network tech for assistance.
Was there anything new installed on your computer before it stopped
working? New programs can sometimes can problems with network access.
Try uninstalling the new software and rebooting.
Were any changes, no matter how apparently insignificant, made on your
machine before the problem started? A computer sometimes can be rather
fragile in both hardware and software. Try to determine if anything happened to
cause it. Be honest with your network support tech.
Are any other computers nearby having the same problem? If so it may be a
bigger problem than just your computer. If other systems are working, try
switching the network cable. If it works then, it could be a cable problem.
