Also just tried adding the cname and get the following

A New record can not be created
An Alias (cname) record can not be added to this DNS name. The DNS
name contains records that are incompatible with the CNAME record.

I am addingecx.images-amazon.com.edgesuite.net. into the FQDN field

Thanks again for the help

I have tried to add it to my dns server as an A record, but I
still
can not resolve it. Obviously it should be getting it from the
root servers, just have no clue why it is not. Basically I can
not see
any pictures on amazon, which is stored onecx.images-amazon.com.
Any ideas would be awesome. When I add a A record it adds a
second (com) folder if that makes any difference. I tried just
adding images-amazon.com, and I could ping that at least, but no
images on amazon.

ecx.images-amazon.com. is a CNAME that points to another CNAME,
and it may not be possible to add an A record and get consistent
results because sometimes the A records are dynamic and the IP
addresses can change at any time.

QUESTION SECTION:
ecx.images-amazon.com. IN A

ANSWER SECTION:
ecx.images-amazon.com. 59 IN CNAME
ecx.images-amazon.com.edgesuite.net.
ecx.images-amazon.com.edgesuite.net. 21599 IN CNAME
a1509.g.akamai.net.
a1509.g.akamai.net. 19 IN A 209.8.115.118
a1509.g.akamai.net. 19 IN A 209.8.115.111

How are you adding the A record?

The way you would add a record for this name is to create a zone
named ecx.images-amazon.com, and create a CNAME, leave the name
field blank, and enterecx.images-amazon.com.edgesuite.net. into
the FQDN field.
I would not create the second CNAME because it would be very easy
for that record to change, in fact it would be just as easy for
any of these to change, but that's why Amazon uses CNAMES, they
have subbed out the web service.


Did you guys ever figure it out? I have the same issue loading Amazon
pages. If I use a Windows 2003 DNS I can't load the images but if I
use a Windows 2000 DNS it works. Any help will be much appreciated.
Thanks, Julian


I have no problem resolving these names with my Win2k3 or Win2k DNS servers.

That said, there isn't anything you can do to fix this mess, after some
testing on ecx.images-amazon.com, I have found that Amazon's hosting
provider ignored RFCs, there are two CNAMES existing on the same node. Most
DNS servers won't even allow this, because a CNAME is not supposed to exist
on the same node as another record. To make things worse, these CNAMES point
to other CNAMES.

You can try running this command on the DNS server.
dnscmd <servername> /Config /EnableEDnsProbes 0
