Best way is probably to let reinstall them, here someone has a solution for that: http://www.tomshardware.co.uk/forum/44768-63-reinstall-microsoft-teredo-tunneling-adapter It is rather one long sentence, but I think he is right.

The teredo tunnelling adapter is necessary to translate/interpret network/internet requests in Windows, so you should leave it alone.

According to http://h30434.www3.hp.com/t5/Notebook-Operating-Systems-and-Software/Microsoft-Teredo-Tunneling-Adapter-quot-device-is-not/td-p/4090294 they said: "Right click and remove all the Teredo Tunneling Pseudo-Interface. Restart the computer. You could Update Driver Software by right clicking, browse computer for driver software. Select let me pick from a list of device drivers on my computer-> network Adapter > Microsoft > Microsoft Teredo tunneling adapter. You can turn on system restore by following this document."

what you need to do is open up your device manager, you then need to click the action tab at the top and click add legacy hardware
then click next and next again it will then scan and find nothing click next on the screen after that.
Wait a minute and you will see a list of hardware appear, scroll down and choose network adapters then click next, then from the left column choose Microsoft then in the right hand column scroll down and choose Microsoft Teredo Tunneling Adapter, then click next and this will install it.
To check just make sure it is set to show hidden devices, right click on device manager on the right and click view then show hidden devices

they have not made a PC under the IBM brand name for quite a while. (2005) It is lenovo now. Go to their support website and download the Network Drivers for your exact model and install them. Sometimes there are more than 1 option, so you may have to try multiple ones.

Obviously you will have to use a different PC to do this....or connect a wireless adapter to your PC (if you have 1 to borrow AND you have a wireless network available where you are.

If this message is in windows, then it is all driver problems. Try going to the intel website and looking up your motherboard, there should be several drivers in multiple categories to download, or one package, get the newest ones and install them all. Intel Driver Update Utility

Uninstall it.
Ok so sometimes this IPv4 to IPv6 shim can become a problem and in some cases it does not appear in the list of adapters where you can quickly disable it. Fortunately there is a way to quickly disable the Teredo Tunneling interface using the command line. Open an elevated command window and type the following command:
netsh interface teredo set state disabled
