Auto Troubleshoot and Fix Internet and Network Problems in Windows 7

March 3, 2010 | Filed under Windows 7


Windows 7 is a smartest operating system compared to all previous versions of Windows. It comes with a lot of nice and useful features to help any computer user that are not familiar with computers to troubleshoot problems. When you encounter a networking problem such as unable to connect to the Internet, browse a website, or getting an IP address conflict, Windows 7 has a built-in feature called Windows Network Diagnostics to help you automatically find and fix the network issues.

I will show you two ways on how to access this hidden feature in Windows 7. The easier way is just to click on the Windows 7 start orb menu, and then type the word “network troubleshooter” in the box where it says Search programs and files. You will see “Identify and repair network problems” appear on the list and all you need to do is just click on it to launch the network diagnostics.

For power users or programmers that would like to implement a button in their tool to launch Windows Network Troubleshooter, here is the command line to launch it. You might want to change the drive letter to point to where Windows is installed.
C:\Windows\system32\Rundll32.exe ndfapi,NdfRunDllDiagnoseIncident

If there is no problem with your network, the scan only takes maybe 1-2 seconds. If there are issues, the scan will take slightly longer to complete and it will try to fix the issue automatically without asking the user to do anything.

There are other tools found in Control Panel to troubleshoot network and internet problems as well. Go to Control Panel, Troubleshooting, Network and Internet. You will see there are a few categories for you to select and allow Windows 7 to troubleshoot them.
