Vista - Help with Teredo service in Vista.

My Teredo service has a problem and I was wondering if anyone knows hows to
reinstall this service? If reinstalling would fix the problem or if I should
just do a system recovery to try to fix it? Can someone help me with this or
does anyone know if any of these things will fix it?
Thanks in advance!

This is what Device Manager says about it:

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


This is what cmd shows about it:
