Strange subdomain problem in BIND

Wow, it is amazing how many people have been able to register the domain
"mydomain.com".  Posting the real domain name on this list will almost
always provide you with better and more accurate responses to your
questions.  Of course, everything you get for suggestions are guesses
without a real domain name...

My vote is that negetive caching is the problem, as Kevin Darcy has
suggested.

You may also want to tail -f your syslog file and grep it for the domain
name in question while you are reloading the name server.  If the zone is
taking errors, you will see them there (by default on most systems...)


Thanks,

Dave...

Hi,

i would really appreciate your help on this issue, since I wasn't able
to find anything about this. So, this is the scenario:


My server (ns0.mydomain.com) is set up as primary DNS Server for
www.mydomain.com. Everything seemed to work okay, until i tried to
create a subdomain, let's say mail.mydomain.com. I added a record into
the zone file,restarted the server .... and nothing happens.  Pinging
the subdomain from outside results in "host unknown". I tried it with
another domain, it works there! Could please figure out what could be
the problem?


; Zone file for mydomain.com

$TTL 3D
@       IN      SOA     ns0.mydomain.com. office.mydomain.com. (
                        2002060801      ; serial, todays date + todays
serial #
                        8H              ; refresh, seconds
                        2H              ; retry, seconds
                        4W              ; expire, seconds
                        1D )            ; minimum, seconds

          IN      NS      ns0.mydomain.com.   ; Inet Address of name
server
          IN      NS      ns2.someother.com.
          IN      A       11.22.33.44
mail      IN      A       22.33.33.11 ; THIS DOESNT WORK (points
outside)
ns0       IN      A       11.22.33.44
www       IN      A       11.22.33.44

Adding ANY subdomain for this domain results in failure. Any ideas?
Your help is greatly appreciated. I'm quite lost in this DNS problem.
I'm running BIND 9.2.0

Best Regards,

Lucas
