teredo tunneling pseudo interface

Under the General tab "Windows cannot start this hardware device because its
configuration information (in the registry) is incomplete or damaged. (Code
19)"

I deleted this from the device manager-Teredo Tunneling
pseudo-interface(driver)
My vista computer xps 1210 will only access:local only!Please help-Where and
how do I download this driver????????????-Thank you from a Italian Boy

I had the same error with teredo and I assumed it was the reason that my
laptop couldn't get online so thinking it was hardware i could just re-detect
I uninstalled it. I am still a bit confused as to whether I need it teredo,
is it intended to ensure my computer is forward compatible or do i need it
now? At any rate I would prefer to bring it back but i can't figure out how.

any ideas?
