In reply to Abdul Raqeeb Kola's post on September 3, Hi Abdul No the computer is not attached to a domain. No change after disabling IPv6, no change after using a fix IP address. See below after my message. I have a very good knowledge of networking and security but this is definitely very Microsoft OS related and I am not specialized enough to go further what I did before, so any expertise welcome!

I used Systeninternals "Process monitor" tools to trace a ping on the deficient machine. In the trace result I cannot see any attempt to call dnsapi. I can send you the trace if you like.

In reply to Gautier's post on September 3, For example, if the machine running the application you are troubleshooting has an IP address of Save the settings to enable the rule, then reboot the router to finish the job.

In those cases, the machine can be placed in a network DMZ, or demilitarized zone. Putting a system in a DMZ allows all of its ports to be accessed from the Internet. Open a Web browser and type Enter the IP address, save the settings, and reboot the router; that system should now be in the DMZ. Like any other peripheral in a Windows PC, the network controller requires drivers to operate. Those drivers tell the operating system how to use a device and occasionally need to be updated to resolve issues or add new features and capabilities.

Updating network drivers in Windows is usually done in one of three ways: through the Windows Update software, by downloading and running an executable installer, or by manually choosing a driver through Device Manager.

When possible, use the first method: Updating a driver through Windows Update is easy and automatic. Unfortunately, manually installing a driver through Device Manager is a bit more complex. Before doing a complete reinstall, determine if your problem can be fixed by performing a Startup Repair.

This will replace your operating system files that may have become corrupt. The most common use for a startup repair is fixing the Windows load sequence. If your computer no longer loads Windows, then a startup repair may fix your boot process and allow Windows to load again. Insert the Windows 7 CD. Make sure your computer is set to boot from CD. To do this, enter the BIOS immediately after your computer starts. You will see the key to press underneath the manufacturer's logo. The most common keys are F2, F10, F12, and Del.

Enter Windows Setup. This will take you into the Windows setup. Files will be loaded for a few moments, and then you will be presented with a screen asking for your Language and Time preferences. These should already be set correctly. Click Next to proceed.

The program will take a moment to search for your Windows installation. Select your installation from the list and click Next. For most users, there will only be one installation listed.

Select Startup Repair. The Startup Repair tool will begin searching through your Windows files, looking for errors. Depending on the errors it finds, it may suggest solutions or repair them automatically.

Remove any flash drives or external hard drives, or Startup Repair may not function properly. Click the finish button. Once the repairs are complete, click the Finish button to start Windows normally. If Startup Repair did not detect any errors, then you will not be presented with this screen. Method 2. Launch the System Restore tool. Depending on whether or not Windows will boot, you have two different ways to get to the System Restore tool.

If Windows will not load, follow steps in the previous section to enter the System Recovery Options. From there, select System Restore.

Select your restore point. You can choose from restore points you created, automatically scheduled restore points, and restore points that were made during the installation of certain programs and Windows updates. You can only restore your computer to dates that are listed here. Click Next, then Finish. Click Yes for the final confirmation.

Your system will begin the restore process. Your computer will automatically restart during this process. The restore may take several minutes.
