Maintaining computer system and network increases efficiency and saves you from the
hassle and expense associated with major repairs. However, it is essential to understand
how to schedule maintenance plans and implement it accordingly. By learning when
maintenance is practical and developing a scheduling strategy, you can set up
maintenance strategies that are beneficial to your computer system and network.
The following are the procedures on how to maintain computer system and networks:
1. Create an Equipment Maintenance Schedule
In order to perform the maintenance of your computer efficiently, a maintenance
schedule is made to
guide the personnel in
the proper maintenance
procedure. This will help
them
remember
the
maintenance task that
needs to be done in
order to improve the
functionality
of
the
computer system and
networks.
2. Create a Maintenance Checklist
To determine if the maintenance program is implemented according to what is
planned, an assessment must be done. The result of the assessment will then be
recorded and reported to the proper authorities for immediate action. The
assessment is through regular inspections which assure that the maintenance
activities are done on the date and time they were was planned and that the
performance levels adhered to the defined standard.
COMPUTER and NETWORK MAINTENANCE CHECKLIST
Performing routine checks like checking your smoke alarms in your home and making
sure your car has been serviced at regular intervals are extremely important. Equally as
important is the routine server and network maintenance and checks on your
information technology systems. Most organizations already have monitoring in place
but periodic maintenance must also take place. So whats the difference between
monitoring and performing maintenance? Even if your a constantly monitoring your
equipment you might ask yourself, why should you also do maintenance?.
Monitoring is something you usually do in real time and you will always continue to do.
Maintenance is something that would typically have a checklist attached to a process
and will be done on regular intervals. A maintenance checklist is something that should
always be done to ensure that everything is checked off and not missed.
Step 1: Anti-virus
Update your anti-virus software and run a scan.
How you do a scan will depend on what program you’re using but most have
very clear instructions right from the
start. Unless you know there’s a problem
I recommend doing the programs’ default
scan. You only need a full scan if you
know you’ve got a virus and the default
hasn’t found it. I also recommend
plugging in any external hard drives so
they get checked at the same time.
Step 2: Anti-spyware/anti-malware
Most anti-virus programs do a basic
spyware check too, but do both to make sure. There are many options for
spyware removal software, Malware Bytes Pro, Super Antispyware and Spybot:
Search and Destroy are recommended. Many also offer to protect your browser(s)
against future incursions which I’d recommend as it can save you a lot of time
and trouble.
Like anti-virus programs how they work will vary but it’s usually easy to see
what you need to do, often you just click a button and let it go.
Step 3: Empty your recycle bin (best done with CCleaner)
Just because you’ve deleted something doesn’t mean
it’s actually gone, if it’s sitting in the recycle bin then
it’s still on your hard drive and still taking up
memory. Disc Cleanup (See Step 4) will empty the
recycle bin automatically, but I like to do it manually
just in case anything important ended up in there by
accident.
There should be a recycle bin icon on your desktop,
but if not it’s on the start menu. Just open the folder,
check what’s in there and click ’empty recycle bin’.
Step 4: Disk and Application/Software Cleanup
This is another easy step because it’s built into Windows. You’ll find it by going
to Start>All Programs>Accessories>System Tools. Pick the drive you want to
scan (your main hard drive(s), any that are just used for data storage won’t have
problems) and let it go.
It finds files that aren’t needed any more and odd bits of data that got left behind.
Stuff like web pages that were archived automatically, temporary files that never
got deleted, old service pack backups and so on. It then presents you with a list
of what it’s found and how much memory each item is taking up. You can pick
and choose which ones to delete but I like to do the whole lot.
Also look in control panel for unwanted or unnecessary programs. Uninstall
anything that has leached on to the system over time such as Internet Browser
toolbars.
Remove any unwanted or unnecessary Internet Browser extensions, plug-ins or
add-ons
Expert level technicians may want to clean up the system registry (do not
attempt this unless you are absolutely sure you know what you are looking for)
Step 5: Defragment
Again this program comes with Windows, it’s in the same place as the Disk
Cleanup tool. It’s a straightforward process; pick a drive, ask for analysis and if
it says it needs defragmenting let it do its thing.
Step 6: Configure your startup
This is a bit more complicated, but extremely useful. First, you need to open the
Run program. Type ‘msconfig’ and click OK. When it opens go into the ‘Startup’
tab. This is a list of everything that runs automatically when you switch your
computer on. If you’re not sure what something is, it’s best left alone but there
should be some familiar names there too like iTunes or MSN.
Ask yourself if these really need to be running in the background each and every
time you switch the computer on and uncheck any that don’t make the cut.
Then click apply, then OK. Next time you start up your computer those programs
won’t start with it. You can still open them manually and they’ll work exactly the
same way, but they won’t be hogging resources when you’re not using them.
Step 7: Check Windows Updates, Update plugins and basic applications
Check Microsoft Updates, including weekly scheduled updates as well as the
latest Service Packs.
Some of the applications to look for to update:
✓ Browsers – Google Chrome, Safari, Opera and Firefox
✓ Messaging – Skype, Windows Live Messenger,
✓ on – 7-Zup, PeaZIP, WinRAR
Step 8: Check file backup plan and create system recovery disks if
applicable
Make sure to have a file backup plan and create system recovery disks if
available. System images are always a good idea as well.
Step 9: Clean and dust internal computer parts and fan (check fans and
computer temp.)
Network Maintenance Tasks
Network maintenance tasks are those tasks which network administrators perform on
a day-to-day basis, allowing for the upkeep of the network. Some of the more common
network maintenance tasks include, but are not limited to, the following general
activities:
1.
2.
3.
4.
5.
6.
7.
8.
9.
Installing, replacing or upgrading both hardware and software
Monitoring, tuning and optimizing the network
Documenting the network and maintaining network documentation
Securing the network from both internal and external threats
Planning for network upgrades, expansions, or enhancements
Scheduling backups and restoring services or the network from backups
Ensuring compliance with legal regulations and corporate policies
Troubleshooting problem reports
Maintaining and updating device configurations
Installing, replacing or upgrading both hardware and software
Hardware and software installation, replacement and upgrades are very common
network maintenance tasks. In a Cisco internetwork, this may include replacing older
or failed hardware, such as switch linecards and supervisor modules in Catalyst 4500
and 6500 series switches, for example, as well as upgrading the Cisco IOS images to
current revision or patch levels for routers and switches alike.
Monitoring, tuning and optimizing the network
One of the core facilitators of an effective network maintenance solution or strategy is
proactive monitoring. Proactive monitoring allows potential problems to be detected and
remedied before they cause an outage or affect operation. Event logging and network
monitoring can be used to proactively react to network or system alerts and be used to
do the following:
1.
2.
3.
4.
Verify the performance of the network and all internetwork devices in the network
Baseline the performance of the network itself
Understand the amount of direction and traffic flows in the network
Identify and troubleshoot potential network issues
Documenting the network and maintaining network documentation
While most network engineers consider documentation a rather mundane and even
lowly task, it is important to understand that documentation is a critical component of
network maintenance as well as troubleshooting and support. It is important to
understand that different organizations have different standards for acceptable levels of
documentation. There are several guidelines or recommendations that you should follow
when documenting the network:
1.
2.
3.
4.
5.
Determine the scope of responsibility
Understanding the objective
Maintain documentation consistency
Make sure that the documentation is easily accessible
Maintain the documentation
The first guideline is ensuring that you understand your scope of responsibility. That
is, it is important to understand what it is that you are responsible for. For example,
you may be working in an organization that has a voice, security, storage and network
team all under the Information Technology (IT) department umbrella. Rather than
attempting to create documentation for all the teams, you should make sure you should
only document those networks and devices that are within your administrative
responsibility.
It is important to understand what the documentation will be used for. A common
mistake that is made by network engineers is either including too little or too much
information within the documentation. Take time to fully understand what the
document you are creating will be used for and take into consideration the audience the
document is targeted to and what information would be useful or excessive for that
particular group. Over-documentation makes documented information hard to
understand. On the other hand under-documentation makes network support and
troubleshooting difficult to perform.
Consistency when creating network documentation is a key component that should be
adhered to as much as possible. In most organizations, design and documentation
templates are available for reference when creating new documentation. Maintaining
consistency increases the usability of those documents and makes them easier to
understand for everyone else.
No matter how great the documentation that is created is, it helps no one if the
documentation cannot be accessed by those that may need it to support troubleshooting
or support functions. Where possible, documentation should be stored in a location that
is readily and easily accessible to all those that may use it, such as on a secure network
location or share. In some cases, depending on the organization, it may be necessary for
documentation to be stored in a secured, offsite location for disaster recovery and
business continuity purposes.
And finally, once the documentation has been created, it is important to ensure that it
is always maintained and up-to-date. Network diagrams from years ago may contain
misleading and incorrect information that may hamper troubleshooting information.
Network documentation should be considered living documentation that changes at the
same rate as the network. Following the completion of each network project, existing
documentation should be updated to reflect the changes that were made to the network.
Although there are no standards that determine what information should and should
not be included in network documentation, most organizations and businesses have
their own standards for what should be included in the network documentation. It is
important to adhere to these standards and guidelines when creating documentation.
From a best practice’s perspective, network documentation should include the following
information at a minimum:
1. Information about the interconnects between devices for LAN and WAN
connections
2. IP addressing and VLAN information
3. A physical topology diagram of the network
4. A logical topology diagram of the network
5. An inventory of all internetwork devices, components and modules
6. A revision control section detailing changes to the topology
7. Configuration information
8. Any original or additional design documentation and notes
9. Data or traffic flow patterns
Securing the network from both internal and external threats
Network security is an integral component of network operation and maintenance. It is
also very important that consideration be given to both internal and external
threats. While most organizations have a dedicated security team, monitoring and a
structured maintenance approach can also be used to discover vulnerabilities or
potential security threats which can then allow for the appropriate action to be taken
before an incident occurs.
Planning for network upgrades, expansions, or enhancements
Using network monitoring, you can identify potential issues before they arise as well as
plan for possible network upgrades or expansions, i.e. capacity planning, based on the
identified potential issues. Effective planning can be used to define the maintenance
tasks required on the network and then prioritize those tasks and the order in which
they will be implemented.
Scheduling backups and restoring services or the network from backups
Backups are a routine maintenance task that is usually given a very low priority.
However, it is important to understand the important of backups – especially when
attempting to recover from a serious or critical failure of the network. Backups should
therefore be considered a core common network maintenance task, and should be
allocated a high priority. It is important to ensure that backups of core network
components and devices are scheduled, monitored and verified at all times. Having up-
to-date backups of core devices can assist in the faster recovery of the network or
individual network components following hardware or software failures, or even data
(configuration) loss.
Ensuring compliance with legal regulations and corporate policies
A structured network maintenance methodology also ensures that the network is
compliant with both legal obligations as well as corporate policies. Regulatory policies,
which are mandatory enforcements of compliance with industry regulations and laws,
will differ for businesses. Regardless of the industry and the requirements, it is
important to ensure the business is following the industry standards as regulated by
the law. Unlike legal regulations, corporate policies will vary on a business-by-business
basis; however, it is still important to ensure that the network adheres to these policies
and
can
provide
the
required
functions.
Troubleshooting problem reports
Troubleshooting problem reports is core network maintenance function. While
troubleshooting methodologies are described in detail later in this guide,
troubleshooting is simplified by a structure network maintenance approach, which
includes documentation, backups, and some form of proactive monitoring system.
Maintaining and updating device configurations
Configuration changes are common because of the day-to-day moves, additions, or
changes (MACs) within organizations. Device configurations may also change due to
scheduled maintenance tasks and planned changes to the network. For this reason,
maintain and updating device configurations is considered a core network management
function. Each time configurations on devices change, they should not only be
documented, but should be saved both on the device and to an alternate backup
location, e.g. an FTP or TFTP server (if one is available).
3. Testing the configured Network
You’ve set up all your network switches, plugged in all the cables, and configured all your
computers. One task remains before you can declare your network finished: You must
verify that the network works as expected.
Here are a few simple tests you can conduct to make sure your network is functional.
1. Check the physical connections.
Check that the Link light — the little red or green light next to the RJ-45 port —
is lit on every computer. You must check this light both on the computer itself
and on the switch or router the computer is plugged into. If this light is not on,
you have a connection problem — most likely a bad cable.
2. Verify that you can log on.
When you’re sure the physical connections are good, you should attempt to log
on to each of your network computers using a valid domain user account.
3. Check the network configuration.
Click
the
Start
button,
type cmd and
press
Enter.
Then,
enter
the
command ipconfig /all and press Enter.
4. This command will spit out numerous lines of information. The line you’re looking
for should resemble this:
IPv4 Address. . . . . . . . . . . : 192.168.1.125(Preferred)
If this part of the output does not show a valid IP address, you need to check that
your IP configuration is set correctly and that your DHCP server is working.
5. Verify that the computers can ping each other.
Another basic test you should perform is to use the ping command from a command
prompt to make sure that the computers on your network can contact one another.
Notes:
Do several ping tests. First, make sure that TCP/IP is up and running by having the computer try to ping itself.
Open a command prompt and type ping localhost. The output from this command will indicate whether or not the ping was
successful.
Next, try to ping your servers by name. For example, if your file server is
named FileServer01, use the command ping FileServer01.
4. Identify Network Problems.
When you suddenly cannot connect to the Internet, any of several things could be wrong.
Use this checklist to find and solve common Internet connection problems.
1. Unplugged Network Cable
Unplugged or loose network cables are one of the most common reasons why you
might suddenly find yourself unable to connect to the Internet. That's a problem
on wireless networks, but on most laptops the wireless-fidelity (Wi-Fi) radio can
be inadvertently shut off instead. On home networks, it's also possible that
someone unplugged the router.
Action: Ensure your wired or wireless network hardware is switched on and plugged in.
2. Website Temporarily Offline
What may seem to be a network problem connecting to the Internet is sometimes
simply a Web site (or whatever server is on the other end of the connection) being
temporarily offline.
Action: Before assuming your Internet connection is faulty, try visiting several popular
Web sites rather than just one.
3. IP Address Conflicts
If your computer and another on the network both have the same IP address, the
conflict between them will prevent either from working properly online. Figure
140. Error Messages 200
Action: To resolve an IP conflict, follow these instructions to release and renew your IP
address. If your network uses static IP addresses, manually change your IP to a different
number.
4. Computer Firewall Malfunctions
Firewall software running on most computers is intended to prevent unwanted
network traffic from disrupting its operation. Unfortunately, these software
firewalls can malfunction and start blocking valid Internet traffic. When two
software firewalls, such as Windows Firewall plus a third-party product, are
installed on the same computer, contention between the two can also incorrectly
block traffic.
Action: If you have recently installed or upgraded software firewalls on your computer,
temporarily disable them to determine whether it may be the cause of Internet connection
problems.
5. Outside Wireless Signal Range
The performance of Wi-Fi network connections depends on distance between the
device and the wireless access point. The farther away a Wi-Fi device is, the
slower the local connection generally runs, until it breaks altogether. Wireless
signal interference in the area can also limit the effective range of a Wi-Fi
connection. Whenever you are unable to reach the access point, you also cannot
connect to the Internet, obviously.
Action: Use one of the options written below to measure the strength of your wireless
signal and try these ideas to expand the range of your Wi-Fi. Ideally, you should place the
router at a height in some central location and away from other cordless devices. Make sure
that the router is not placed near something metallic (like an almirah or window grills) as
that will weaken the wireless signals. Avoid mirrors as they can reflect the wireless signals
away from the desired direction. Wireless routers generally ship with omni-directional
antennas but you can replace them with more powerful uni-directional antennas and that
will keep the signal from getting broadcast in all directions.
6. Wireless Network Configuration
Wi-Fi networks with encryption options like WPA or WEP turned on require
computers to use matching security keys when connecting. If someone changes
the encryption keys or password on the access point, devices that worked before
will suddenly be unable to establish sessions and Internet connections. Likewise
(though less likely), if the access point settings are changed to require using a
specific Wi-Fi channel number, some computers may be unable to discover it.
Action: Confirm that the Wi-Fi channel number and encryption keys on your router have
not recently changed (check with the network administrator if necessary). When using a
hotspot, follow the provider's instructors for signing in carefully.
7. Broadband Router or Access Point Malfunctions
Home networks that use broadband routers are easier to manage than those
without one, but technical glitches with the router can also prevent computers
from connecting to the Internet. Router failures are caused by overheating,
excessive traffic, or simply a faulty unit. Typical symptoms of a flaky router
include computers on the network not being able to obtain IP addresses, or the
router console not responding to requests.
Action: Check the router's lights and console if possible, to ensure it is running and
responding properly. Troubleshoot and reset the router if necessary. Change the old router
if necessary.
8. Blocked By Your Service Provider
Internet Service Providers (ISPs) can choose to block access from your account if
you fail to make payment or otherwise violate the provider's Terms of Service.
Especially when using paid hotspots that charge by the hour or day, sometimes
people forget to keep their subscription updated. Other common reasons an ISP
might block your account include exceeding bandwidth caps, sending spam email, and downloading illegal or inappropriate content.
Action: Contact your ISP if you suspect your account has been blocked.
9. Computer Glitches
Computers suffer from technical glitches or malfunctions. Although relatively
uncommon nowadays, a computer's network adapter hardware might suddenly
fail due to overheating or age. Failures in the operating system software that
control the adapter, on the other hand, can occur frequently especially with
computers that are heavily used. Viruses and worms also may disable or block a
computer's network interfaces from functioning properly. If using a laptop or
other mobile device, transporting it from one location to another can corrupt the
state of its network.
Action: Check the computer and remove any malware that you will find. On Windows
computers, try resetting the network connection. Reboot the computer if necessary.
10. Network Downtime
Those using satellite Internet service may notice they cannot connect to the
Internet during periods of very bad weather. Providers in dense urban areas
(including cellular Internet carriers) sometimes are unable to support 203 peaks
in network traffic that causes sporadic outages for some customers. Finally, those
who subscribe to newer or more complex forms of Internet services (such as fixed
wireless broadband) may experience more downtime than others as providers
encounter more issues with relatively less mature equipment.
Action - If all else fails, contact your Internet provider to verify whether they are
experiencing an outage. Some providers also give advice on troubleshooting problems
connecting to their network.
