Weird intermitten problem with DNS.

[Richard Hyatt]

The NS records from your server [216.226.24.51] return different NS
records than the ones from the TLD. It maybe that some ISPs are using a
different resolver and name caching mechanism which could explain why
there's inconsistent behavior.

Subject: Weird intermitten problem with DNS.


Hello, I am not sure if anyone in here may be able to shed some light on
this situation, but I sure hope so.  I have a few different servers
spread across the US. Some of them are just plain old Red Hat and some
of them are Red Hat with Ensim on it.  One of my customers has several
sites that get a lot of traffic, and he has people complaining all of
the time that they cannot get to the site.  When they try and ping the
domain it gives them a "ping request could not find host domain.com".
When I have them ping the IP it also times out.  I can always get to the
domains, and the servers, but several people have told him the same
thing, so it is too much of a coincidence.  Another weird thing is he
has an AOL account that he uses while he is on the road, and when he
dial's up with that account and uses the aol browser he can get to the
domains fine, but when he dials up with aol and then minimizes it and
uses IE he cannot get to the site's.  I figured it was just some weird
aol proxy thing or something, but I don't know.  Here are a couple of
the web site's on the servers that people cannot get to. If anyone has
any idea's as to what the problem may be please post it here. And if you
don't know what the problem is could you please check out these site's
and let me know if you can get to them and what ISP you are using (I
know that is a lot to ask, but it would help a lot).

TIA
