I'm copying you personally this time in case you missed my message yesterday.
There is no mystery about DNS servers using port 53 to send queries to
other servers port 53. This is how DNS works on a Windows box. [ () 1]
You do not understand DNS. You also don't understand something about your
configuration (or something about how servers refer queries to other
servers). Read the links I sent you. [ () 2][@3]
Search the newsgroup I pointed you to [ () 4] or find another similar one -
someone else has probably asked this question before. I can't remember the
last time I couldn't answer my own question with a google search. Spend a
little time on it.
If you have no luck, trace the traffic on your secondary server using
ethereal [ () 5] See it talk to the primary and/or the root server. Use
ethereal to figure out why.
Using ethereal is a basic skill. If you don't know it, learn it. There are
newsgroups for that, too, so please don't post your questions about it
here. Things are much more productive when you go to the right place. And
If you can't figure it out, take the ethereal output, clean it up, and post
it to the newsgroup I pointed you to and ask them for help. People are
just sitting there waiting for issues like yours. They like DNS. They care.
Spend some time putting together all of the relevant data. A statement
like "the forwarder is correctly set" means nothing. No one can help you
with that information [ () 6] If it was correct you wouldn't have a
Document all of the settings in the properties boxes for both servers,
change the names and ips, and post that. Do you have recursion checkboxes
set? Root hints? Complete posts get accurate answers.
