Diagnosing and troubleshooting network problems while monitoring a corporate network can be challenging. With the potential for several branches, hundreds or even thousands of hosts, dozens of routers, switches and servers, with different vendors or firmware, as well as an outdated human error, knowing where to start is crucial to implementing a quick solution. There is a single methodology for diagnosing a major network problem, and following its instructions will help administrators maintain an organised approach to solving problems.
The solution of business network problems is usually the work of frontline network support staff: engineers and technicians. Common troubleshooting problems for the Ethernet network include user connection problems and slow networks.
The problem solving the process of a network is of great importance in determining the proper functioning of all processes. It ensures that all problems removed from the system, and there are no more problems that can cause obstacles. However, the problem-solving methodology implies a series of steps that must carry out professionally. Only an expert in this process can solve problems with the network and devise ways to eliminate them. However, one must have a thorough knowledge and a good command of network concepts to be fluent in the problem solving process.
There is a well-planned action plan that you must follow in this regard. There are some steps that the problem solver has to follow in the order given, as it will make your task much easier and less complicated. Next, specify the entire process that is involved in the troubleshooting methodology. Simply by following all these steps in the prescribed order, you can easily solve any existing network.
Identify the problem:
The fundamental step in the problem solving process is the identification of the problem. It is not possible to find a solution without knowing the exact problem that may have occurred with the network. The best way to do this is to identify the symptoms and then reduce the problems that could be responsible for them. In this regard, four steps allow you to identify the problem that may have occurred with the system.
In this step, you need to gather information on any physical problem that could be causing this problem. In this regard, you must first make sure that all cables connected in the right places. You can check it by turning on the network interface card. If the light still fixed, it means that the connection established and that, if it flashes, the traffic transmission is also perfect.
Identify the symptoms:
At this stage, you need to find out the symptoms highlighted by the problem. For example, in this regard, you can type ipconfig / all to determine if the computer is connected to the DHCP server and not to another server that could cause problems.
The next step in the network is to determine if you have a problem with this problem. If it is only you, perhaps the problem may be related to your computer settings. However, if this problem occurs, it can be on a large scale.
Determine if something has changed:
At this point, you need to know if something has changed and if your problem could cause it. For example, if the entire system is updated or supported. If you find that this is the case, now you can focus on this problem to solve the problem.
Try the theory to determine the cause
So, now, you have created a theory that could be a network problem. Now you must confirm this theory to make sure that you give it your energies further. In the meantime, you can also provide a temporary solution to this problem. For example, if DHCP servers are lost, you can manually assign servers to computers. However, this will only be for a short time. Your main task is to confirm the cause of this problem and begin work on it.
Once the theory is confirmed, identify the following steps to solve the problems:
So, now you know that your theory is confirmed, and you will need to find the best possible solution for it. In this regard, you will find the steps that you will need to take to solve the problem. If the problem is serious and requires administrator rights, you must forward the problem to the senior network administrator so that he can make sure that is fixed as soon as possible. However, if the problem is related to something that you can solve yourself, you should begin to formulate an action plan to find a solution.
If the theory is not confirmed, restore the new theory or strengthen it:
If you find that your theory has not developed and the problem you were considering is not the cause of this problem, then you should consider starting again. You will need to go to the first step and repeat all the processes until you find the correct cause of the problem the network is facing.
