How do i Enable Teredo?

:)

 

No Teredo installed

Hi Jay,

Thank you for writing to Microsoft Community Forums.

Before we proceed, could you please confirm a few things for me?

1. The make and model of your system?
   
2. The Windows 10 Build you are using?
   

Systems communicate with one another using a certain predefined set of protocols, when systems within a network are using different protocols but are trying to communicate with one another it may require a translator to enable
this communication. This is where the Teredo Tunneling comes in. It facilitates the connectivity between devices behind routers that use network address translation (NAT) and thus enable this communication.

Given that you have already tried to enable the Teredo through the device manager and the netsh command through the command prompt, we have a few more steps that we could try to resolve this issue.

Check and make sure that no VPN client is blocking the Teredo connectivity.

Steps:

Manually enable the Teredo through the registry.

Disclaimer: Important this section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these
steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

To take a backup or restore the registry click
here.

Check the iphlpsvc registry path:

1. Right-click the Start icon, type in cmd, Right-click on it and 'Run as administrator'.
   
2. Run the following command from the Admin command prompt: reg query HKLM\System\CurrentControlSet\Services\iphlpsvc\Teredo
   
3. If you find this output: Type REG_DWORD 0x4
   
   You will need to Re-enable Teredo by running the following command from the Admin command prompt: netsh interface Teredo set state type=default
   

Check the TcpIp6 registry path:

1. Right-click the Start icon, type in cmd, Right-click on it and 'Run as administrator'.
   
2. Run the following command from the Admin command prompt: reg query HKLM\System\CurrentControlSet\Services\TcpIp6\Parameters
   
3. If you find the output, and the value displayed is not 0x0. Example: DisabledComponents REG_DWORD 0x8e
   
4. You will need to Re-enable Teredo by running the following command from the Admin command prompt: reg add HKLM\System\CurrentControlSet\Services\Tcpip6\Parameters /v DisabledComponents /t REG_DWORD /d 0x0
   

Hope it helps.

Can You Please fix the teredo adapter problem already?

Hi Mr Overshield,

Teredo being disabled is one of the possible reasons why you're unable to fix the Teredo problem as well as can't find it under hidden devices. To re-enable your Teredo on your device, I suggest that you follow the steps below:

1. Type in cmd in to the search bar on your desktop and right click on Command Prompt and run it as admin.
   
2. Type in netsh interface Teredo set state type=default
3. Kindly restart your computer to let the changes take effect.

Note: No need to reinstall the Teredo as it will install itself.

Teredo Tunneling Pseudo-Interface Adapter Missing

Hello,



Thank you for writing to Microsoft Community Forums.



I would like to know the reason you are trying to install the Teredo Tunneling Pseudo-Interface Adapter, so that we can suggest you alternatives. If you are trying to install it for Xbox app on Windows Computer then we can have the dedicated team look
into it.



However here are some steps that you can try. To enable Teredo adapter:

• Right-click the Start icon, and then select
  Command Prompt (Admin).
  
• Run the following command from the Admin command prompt:
  
  • netsh interface Teredo set state type=default
    
• 
  

**The Microsoft Teredo Tunneling Adapter will reinstall automatically. Don’t install the Teredo Tunneling Pseudo-Interface adapter manually in Device Manager, as this may cause issues with Teredo functionality**



Also check to see if Teredo is disabled in the registry by a program or by a manually configured registry value.

• Right-click the Start icon, and then select
  Command Prompt (Admin).
  
• Run the following command from the Admin command prompt:
  
  • reg query HKLM\System\CurrentControlSet\Services\iphlpsvc\Teredo
    
  • If the output includes the following line, Teredo has been disabled:
    
  • Type REG_DWORD 0x4
    
• You can re-enable Teredo by running the following command from the Admin command prompt:
  
  • netsh interface Teredo set state type=default
    

Check the TcpIp6 registry path:

• Right-click the Start icon, and then select
  Command Prompt (Admin).
  
• Run the following command from the Admin command prompt:
  
  • reg query HKLM\System\CurrentControlSet\Services\TcpIp6\Parameters
    
  • If the output includes the following line, and the value displayed is not
    0x0, Teredo may have been disabled:
    
  • DisabledComponents REG_DWORD 0x8e
    
• You can re-enable Teredo by running the following command from the Admin command prompt:
  
  • reg add HKLM\System\CurrentControlSet\Services\Tcpip6\Parameters /v DisabledComponents /t REG_DWORD /d 0x0
    

Important: The registry is a database in Windows that contains important information about system hardware, installed programs and settings, and profiles of each of the user accounts on the computer. Windows often reads and updates the information
in the registry.

Normally, software programs make registry changes automatically. You should not make unnecessary changes to the registry. Changing registry files incorrectly can cause Windows to stop working or make Windows report the wrong information.



**Please take a backup of the registry. To take back up, follow the steps mentioned in article:

How to back up and restore the registry in Windows.




Hope it helps.
