One of the novelties in Windows Vista is the inclusion of the Windows Network Diagnostic tool. This tool can help you identify and resolve with ease most of your network problems. You don't have to be a specialist in computer networks to find out what is wrong with your network or internet connection. You just run the tool and it will report to you the problems that were discovered.
In this tutorial we will show how to use Windows Network Diagnostics to successfully identify connectivity problems.
There are several ways to find this tool. One of them is to go to Control Panel and search the word "network". In the list of search results you will find the Network and Sharing Center. Beneath it, you will see a link called Identify and repair network problems. Click on it and Windows Network Diagnostic will be launched.
Another option would be to go to Control Panel -> Network and Internet -> Network and Sharing Center-> Diagnose and repair. Alternatively, when you access your Network Connections, right click on your network icon and choose Diagnose.
When launched, Windows Network Diagnostic starts the process of identifying your connectivity problems.
After a while the tool will tell you if it managed to find any problems or not. When a problem is found, Windows Network Diagnostics will show the description and propose a solution, if possible.
In the above screenshot you can see there was a problem with our DNS server. When you click on the proposed solution, Windows Network Diagnostics tries to apply a fix that might repair the problem.
After the repair is finished, the tool checks if the problem persists or not.
As you can see in the screenshot below, in our case, the problem could not be fixed. In this scenario, the remaining solution is to contact our internet provider and inform it about our problem.
There are many other possible scenarios of things that could go wrong. The good news is that Windows Network Diagnostics will help you identify them in a few seconds, with only one click.
