What is a Microsoft Teredo Tunneling Adapter?

kiwikidd77, May 2, 7:26pm
Looking under device manager in my windows 7-- 64bit Ultimate system it has a yellow triangle next to it with an exclamation mark inside.

Tried updating the driver but it reports its up to date.

Any ideas?

Are you running any firewalls?

Yes, Zone Alarm Free. does it make a difference?

All my other programs and drivers can be updated as needed with no change in Zone Alarm settings.

I think there has been problems with zone alarm. Check ifthe Enable IPv6 box in Firewall | Main | Advanced is ticked or not (you want it ticked).

Toredo is a 6to4 tunnel which gives you access to the IPv6 internet.

There's really nothing yet on IPv6 that you can't get to on IPv4, and by the time there is your ISP will start providing 'native' IPv6 and you won't need a tunnel, so I wouldn't worry about it.

The problem is that in ZA free there is no such IPv6 box. It only exists in the commercial versions of Zone Alarm. Is there any other way to solve this problem?

I found a solution how to make it work:

1. Temporarily disable Firewall and third party antivirus program on the computer for a test.

2. Verify relevant services


a. Click "Start", type "services.msc" (without quotation marks) in Search Bar and press Enter.

Note: If you are prompted for an administrator password or confirmation, type your password, or click Continue.

b. Right click the "Peer Networking Grouping" service and choose Properties.

c. Please check if the service is started; if not, please click the Start button and see if it works.

d. You may also choose Automatic next to Startup type.

e. Click OK.

f. Please repeat the above steps with another service: PNRP Machine Name Publication Service.

3. Modify IPv6 registry key to enable IPV6


a. Click Start, type regedit in Search Bar, and then click regedit in the Programs list.

Note: If you are prompted for an administrator password or confirmation, type your password or click Continue.

b. Locate and then click the following registry subkey:


c. Check whether the "DisabledComponents" registry key exists. If so, let's move on the next steps.

d. Double click the "DisabledComponents" registry key and modify the value to 0.

(If the key doesn't exist, please create the key above and assign the value 0)

e. Exit Registry Editor, and then restart the computer.

Of course all the last junk doesn't help with the basic problem: How do you get the driver which windows says it needs
