Basic Troubleshooting


Basic troubleshooting involves identifying the problem and then determining the root cause. It involves using basic tools and techniques to help find the problem. Once you know what is causing the problem, you can try to fix it. The process will be much faster if you split the testing process into two parts to try to isolate the problem.

Principles of troubleshooting

Troubleshooting is the process of determining the root cause of an issue. If a problem has several causes, troubleshooting may not be sufficient to find the cause. In many cases, the initial focus will be on environmental or system changes. For instance, a printer may have worked before but has now failed when plugged into a different outlet. This is known as a “correlation” but does not necessarily indicate causation. To determine the cause of a problem, troubleshooters need to use critical thinking and evaluate the available options.

One of the most important principles in troubleshooting is the ability to reproduce the problem. This means breaking down the system into its simplest form and understanding its behaviour. Then, troubleshooters can substitute known-good components for suspect ones. Unfortunately, while this method can result in a temporary fix, it can create further problems or even seriously damage the system.

Regardless of the cause of a problem, troubleshooting techniques follow several principles:

  1. The problem should be clearly defined.
  2. The cause and effect should be studied.
  3. The solution needs to be evaluated in a testing environment.


You can use many basic troubleshooting tools to analyze your network performance. Some of them are built into your operating system. Some are easy to use, such as ping or traceroute. Other tools can help you diagnose specific problems, such as a slow network connection or a security issue.

Basic troubleshooting tools are essential for any network administrator. They allow you to detect and fix many different network problems. They are also extremely helpful when you’re trying to determine whether a security threat has affected your network. But, of course, some tools are better than others, depending on your needs and preferences.

A good network troubleshooting tool is netstat, which displays all network connections. It also allows you to see what services are associated with active ports. This tool is free and installs on Linux and Windows Server. However, it has various features, so it will take some time to learn how to use it. Alternatively, you can use Paessler’s PRTG, a complete network monitoring system. It can diagnose network issues down to the protocol stack and determine the root cause.

Another tool that helps you troubleshoot your network problem is the ping utility. This application works by exploiting the Internet Control Message Protocol (ICMP). It sends a small packet to the destination computer, responding with an ICMP echo. It can also be used to diagnose network routing problems.


Troubleshooting involves identifying and eliminating faults in a system. The first step in troubleshooting involves thinking about why a device may have failed. Many times, a single component could be the culprit. In such cases, serial substitution can fail to resolve the problem. Sometimes, a defect can also be the cause of the failure.

If the error is caused by hardware, check whether the components are connected properly. Another important step is restarting the computer. This can help fix many common computer problems. Similarly, it is important to update your operating system and applications to prevent problems in the future. If there are updates available, install them.

It is a good idea to consult the vendor’s documentation before you start troubleshooting. Many product manuals will include a troubleshooting section. You can also consult with more experienced technicians who may be familiar with similar problems. However, it is advisable to avoid repeating the same question several times, making you appear uninformed. It is also important to take good notes and heed what the technician says.

While troubleshooting a computer system, remember that it is best to document each step you perform. Not only does it prevent you from making mistakes, but it also helps make it easier for others to identify and fix a problem.
