Teredo Tunneling Psuedo-Interface

Since last couple of days am facing some problems with my Vista desktop network connection. When I checked the same in Device Manager I found Marvell , NVIDIA controllers and Teredo Tunneling Pseudo-Interface. When I checked its properties, it show up “This device cannot start. (Code 10).”

I don’t know what exactly could be the reason but I suspect the drivers. What you guys say?

Teredo tunneling has to do with IPv6 and IPv4 where Teredo provides IPv4 NAT traversal capabilities by tunneling IPv6 over the top of UDP/IPv4. http://www.microsoft.com/technet/pro...in/teredo.mspx
