[Hidden-tech] Strange DNS Behavior

[Daniel Lieberman]

Thanks all! I appreciate all the help and suggestions. I decided last night
that I would actually learn how this stuff works and not continue with my
cookbook/magic approach to website configuration: you've provided a great
start for my road to enlightenment.

We actually cut the Gordian knot yesterday by doing what we wanted to in
the first place: having the crazyorchidlady.com site forward to the
forum.crazyorchidlady.com site.

By the way, I think Patrick Foley's explanation was the correct one: we
have been using opendns.com for DNS inside the network, and I guess it just
took them a little longer to catch up.

We got outstanding service and help on this from Tech Support at Hover.com,
where I now do all my domain registrations. I highly recommend Hover.

Yours sincerely,
