How to Fix the Hamachi Tunnel Problem on Windows?

Hamachi is a desktop tool used to create and manage virtual private networks between many distant computers. Most people use it to simulate local area networks, which can be utilized to play some games. However, the Hamachi Tunnel problem prevents users from using Hamachi at all.

The problem manifests itself with a yellow triangle on the taskbar just above Hamachi’s icon. There are no official methods to resolve the problem, but many users have come up with their solutions that have worked for them. We have gathered them in a single article for you to check out!

What Causes the Hamachi Tunnel Problem on Windows?

This issue can be caused by various networking problems, but the most common causes are related solely to the Hamachi program and its drivers. We have compiled a list that covers the most common causes, and you should check it out below to determine your scenario and the best way to resolve the problem!

Solution 1: Disable and Re-enable the Hamachi Connection

Simply restarting the connection can be one of the easiest methods to resolve the problem, which is why we have included it as the first method. Disabling and re-enabling the connection can be done in the Network & Sharing Center and shouldn’t take a long time. Follow the instructions below carefully!

1. Use the Windows + R key combo to immediately open the Run dialog box. Type ‘ncpa.cpl’ in the bar and click OK to open the Internet Connection settings item in Control Panel.
2. This process can also be done by manually opening the Control Panel. Switch the View by setting in the top right section of the window to Category. Click on Network and Internet at the top. Click the Network and Sharing Center button to open it. Try to locate the Change adapter settings button in the left menu and click on it.

3. When the Internet Connection window opens, right-click the Hamachi network connection and choose the Disable entry from the context menu that appears. Wait for a couple of minutes before doing the same, but this time, choose Enable from the context menu. Check to see if the Hamachi Tunneling problem still appears.

Solution 2: Restart the LogMeIn Hamachi Tunneling Engine Service

An error regarding the LogMeIn Hamachi Tunneling Engine service may be preventing Hamachi from opening properly. Services can be restarted rather easily, and this method is easy to perform by anyone! Make sure you follow the instructions below carefully to restart the LogMeIn Hamachi Tunneling Engine service!

1. Open the Run utility by using the Windows Key + R key combination on your keyboard (press these keys at the same time). Type “services.msc” in the newly opened box without the quotation marks and click OK to open the Services tool.

2. An alternative way is to open the Control Panel by locating it in the Start menu. You can also search for it using the Start menu’s search button.
3. After the Control Panel window opens, change the “View by” option at the top right part of the window to “Large Icons” and scroll down until you locate the Administrative Tools. Click on it and locate the Services shortcut at the bottom. Click on it to open it as well.

4. Locate the LogMeIn Hamachi Tunneling Engine Service on the list, right-click on it, and select Properties from the context menu that appears.
5. If the service is started (you can check that just next to the Service status message), you should stop it for now by clicking the Stop button in the middle of the window. If it is stopped, leave it stopped until we proceed.

6. Ensure that the option under the Startup type menu in the service’s properties window is set to Automatic before you proceed with other steps. Confirm any dialog boxes that may appear when changing the startup type. Click on the Start button in the middle of the window before exiting. You may receive the following error message when you click Start:

Windows could not start the LogMeIn Hamachi Tunneling Engine service on Local Computer. Error 1079: The account specified for this service differs from the account specified for other services running in the same process.

If this happens, follow the instructions below to fix it.

1. Follow steps 1-3 from the instructions above to open the service’s properties window. Navigate to the Log On tab and click on Browse…

2. Under the “Enter the object name to select” entry box, type in your account’s name, click on Check Names, and wait for the name to become available.
3. Click OK when finished and type in the password in the Password box when prompted if you have set up a password. Hamachi should now work properly.

Solution 3: Reinstall the Hamachi Virtual Ethernet Adapter

Reinstalling Hamachi’s driver is also a viable way of resolving the problem. Driver issues when it comes to networking are often the biggest culprit, and this method is something that definitely shouldn’t be skipped when addressing this problem. Check it out below!

1. First, you will need to uninstall the driver you currently have installed on your machine.
2. Type “Device Manager” into the search field next to the Start menu button to open the Device Manager window. You can also use the Windows Key + R key combination to open the Run dialog box. Type devmgmt.msc in the box and click OK or press the Enter key.

3. Expand the “Network Adapters” section. This will display all network adapters that the machine has installed at the moment.
4. Right-click on the wireless network adapter you want to uninstall and select “Update driver“. This will remove the adapter from the list and uninstall the networking device.

5. From the next screen that will appear asking you How do you want to search for driver software, choose the Browse my computer for driver software option.

6. Navigate to the folder where you installed Hamachi. By default, it’s C:\Program Files (x86)\LogMeIn Hamachi. You can find the correct location by right-clicking the Hamachi icon on the Desktop and choosing the Open file location option.
7. Click Next and check whether the problem has finally been resolved on your computer.
