Alain,

Why are you using Teredo to begin with? With all it's security vulnerabilities and issues
there are far better and safer solutions to use. My team was aware many of these DNS
issue over 8 months ago with vista but according to Microsoft they "should" be fixed in RC1.
But we haven't done anything with Teredo because that is one of the first things we disabled.
If you need a tunnel broker I would recommend using Hexago's free tunnel broker over
teredo which will also remove DNS issues that is seen with Vista because the tunnel broker
does the heavy lifting.
