I would like to know the proper way to setup an internal dns zone that has
the same name as my public zone. For example if I have FBFALLS.EDU as a
registered public domain how can I setup a local domain called FBFALLS.EDU ?
When I create it everything seems to work fine for about a day then it all
gets goofy (goofy being a huge delay then public resolution instead of
local resolution) I suspect some sort of resolution loop. The clients look
to our local dns server first then 2 public servers, a release/renew fixes
things - for about 24 hours.

any ideas ?
