Help with Teredo Tunneling Pseudo Interface

I'm sure everyone has head about it before, but I've seen as many solutions as there have been questions about it.

My TTPU seems to be malfunctioning. I'm getting a code 10 error... unable to load the driver. Trying to update it has failed, as it simply tells me I have the latest version. At the moment, it's disabled, but I have no idea what it does for me, so I'm worried about having problems leaving it that way. ...of course, since it wasn't working in the first place, maybe not.

How should I go about fixing this thing? If there is a solid, known way to fix it, can someone please post it here? One fix I tried before getting nervous was editing the registry, but the directions given didn't actually lead to where they were supposed to lead, and so I never changed anything.

If anyone knows a good way to fix the driver for this device (or at least to make the system load it properly) please post here. Thanks.

Why are you using it? Is it for accessing your employer's systems from off site? If so you should contact the technicians responsible and have them advise you because that's their job.

Are you talking about what you see in the Device Manager? Click the View button at the top and 'Show hidden devices' and see if there's another Teredo Tunneling Device there which is actually OK. I had the same supposedly malfunctioning one in mine and simply uninstalled it and left the 'hidden' one alone and it hasn't reappeared.

It actually is most likely irrelevant anyway as few people are using this feature in any case. Ask your ISP if they are using IPv6 Internet Protocol yet and they most likely will tell you that they are not, yet anyway. In which case your LAN Connection would look something like this (click to enlarge if necessary):
