vista, dns woes ?

[James Clark Calloway]

It was a global option.

We relied on the unknown classification to get
the dns server defined for the unknown pool.

In that same subnet we have some known devices
that get the "good" dns servers. It's only if you
are unknown that you get into the dynamic pool
and thats where the "bad" dns servers are defined.
