I have just completed a clean install of Windows 7 Ultimate 64 on my system and all is well except for a yellow exclamation mark showing in Device Manager under "Network adapters" and against the item "Teredo Tunneling Pseudo-Interface" 

Looking under the properties for this device shows "This device cannot start. (Code 10)"

I haven't got any idea on what this device is or does.

Could someone please advise on this problem.

Thanks.

Hi Siebert9,

Welcome to Microsoft Answers Community Forum!

First thing I would like to suggest you is to uninstall and reinstall the device from device manager and verify if the yellow exclamation mark disappears.

You can also try updating your network driver by following these steps:

  • Right click the Teredo Tunneling Pseudo-Interface
  • Update Driver Software...
  • Browse my computer for driver software
  • Let me pick from a list of device drivers on my computer
  • Select from the list and update the driver.

Also you may get this mark because the network adapter may not be compatible with Windows 7. Request you to contact the manufacturer’s website and download the latest driver/adaptor that is compatible with Windows 7.

To check for compatibility in windows 7, visit the below mentioned link:

Hope this helps resolve your issue!

Thanks & Regards,

Supreeth - Microsoft Support.

    Let's see...

    As usual we know absolutely nothing about your system.

    Assuming you are following some directions to add the Teredo maybe you are seeing something like this after installing:

    And Device Manager shows a yellow exclamation next to the Adapter like this:

    Here is a generic procedure that for you to follow:

    Click the Start orb/button and in the box enter the following:

    cmd.exe

    Right click cmd.exe and choose to Run as Administrator:

    ![](https://learn-attachment.microsoft.com/api/attachments/43d48d9e-4deb-4d63-b457-9a0aa17604b7?platform=QnA)

    In the Command Prompt window enter the following commands one at a time pressing the Enter key after each:

    • netsh
    • int  teredo
    • set  state  disabled
    • int  ipv6
    • set  teredo  client
    • exit

    You should be seeing something like this as you enter the commands one at a time:

    Close the Command Prompt window by entering exit one more time.

    Restart your system and see how things look in Device Manager now.

    I'm in the same boat as you are PhoenixGTR: and I think its fair to say that for some reason even the  microtechs are either a). none the wiser, or b). as other websites are saying...MS are deliberately doing this in line with their telemetry software that they install on windows machines?!%$* scary! Why else is there multitudes of windows users going thru the same conflicts then?

    Disable is about all we can do from this end, I'm currently looking at shifting to Linux for the above reasons, just gotta get my head around the platform 1st!

    I will also follow a suggested search mentioned in this thread to do a scan of my system: https://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html

    You may want to also follow if you have the time & patience. Cheers !

    Teredo Tunnel Adapter: Error Code 10

    If you are getting Error Code 10 after following all the steps at Teredo Tunnel Adapter then you can fix it by following the steps in this guide. Go to Start and type cmd right click on cmd at the top of the list and select Run as Administrator. If the User Account Control window appears click on Yes. Type all of these commands (very carefully) one at a time and click on the Enter key on your keyboard after each one has been typed in.You must copy the words exactly as shown here, one letter wrong and they won’t function.

    netshint teredoset state disabled

    Leave the Command window open.

    Click on Start, Control Panel, Device Manager. Click on View and select Show hidden Devices.

    Right click on Teredo Tunneling Pseudo-Interface and select Uninstall.

    Close the Device Manager and Control Panel. Back to the Command window, type these one at a time and click on the Enter key after each one is typed.

    netshint ipv6set teredo client

    Close the Command window.

    Open Device Manager again, right click on Network Adapters and select Scan for harware changes, then click on View and select Show Hidden Devices.

    You should now see the Teredo Tunneling Pseudo-Interface entry back in place without the yellow exclamation mark.

    Right click on Teredo Tunneling Pseudo-Interface and select Properties, it should show that the device is working correctly in the Device Status box.
