Download and install DNS Expert from Men and Mice run your domain and see if
the errors mean anything to you at this time 3 are showing up. When that is
all don consider using to do you DNS it is a hell of a
lot better and has name servers spread all over the states.

Subject: [DNS] DNS Problem

Hi to any Guru's out there,

I have had an ongoing problem that effects host lookups from some exernal
systems to (and quite possily every thing else we provide
DNS for) but the mail is the one that is most noticable.

I have rang our registrar, and I'm assured glue etc is all in place.

our names servers are listed as and, the
ttl's are quite low while we have been trying to resolve this problem.

I have a friend who sent me the following:

I set up the DNS packet capturing a few days ago, and I've been doing
DNS lookups for every minute for the last few days.

The lookups fail for the first 7 minutes of every second hour (i.e.
when the cached records have expired and the DNS server must do the
lookup from scratch).

Any help appreciated,

Cheers Tony
