DNS Domain problem due to duplicated website name

[BradQ]

We have a website that is setup as
http://www.clientname.com. We also have a Windows 2000
Server running DNS with the same domain name of
clientname.com. We'd like all the internal workstations
to use this internal server as the DNS server.

However if you specify it in the network settings when
trying to get to the webpage it says its not found since
its looking on the local W2K server instead of the
Internet. How can I change our domain name internally
without a lot of time and work?

The internal clients MUST use the internal Name servers, what you need to do
is create host records in the internal DNS for www or whatever with the IP
of the sites.

You can't without a lot of time and work, it should only take a few secords
for each record you need to add.

The ISP hosting their webapge says its a "virtual ip" and
I cant add a record for the ip. It needs to be added as
the domain name of their website. I don't know a whole
lot about DNS. How do I add this on the internal DNS
machine?

The website still resolves to an IP address. The request is sent in an HTTP
request with the hostheader in the packet, which is what virtual sites look
for. What Kevin is trying to tell you is to create a www record on your
internal DNS and give it that IP it resolves to. This is the usual fix for
this *common* issue with a Split-Horizon zone (same inside/outside names).

You could also delegate a child zone called www to the external DNS that is
SOA for the zone, this way you don't have to worry if they change IPs
constantly.

What is your website address? I'll look it up and tell you what you need to
add. At the very least it may be a CNAME record. I need the website address
to tell you what you need.

The website is: http://www.mt-orthopedic-surgeons.com
The Domain they log on to in the office is: MT-ORTHOPEDIC-
S

I did try adding a www record. I then did "ping www.mt-
orthopedic-surgeons.com" and it resolved to 66.51.120.17.
So thats the ip I added. Now when you put in the URL for
their website you get the ISP's webpage instead of the
correct one. They say its the virtual ip thats causing it.

This on is a simple one, in the DNS console expand forward lookup zones,
open the mt-orthopedic-surgeons.com zone. In the action menu select new
host, in the name field type www in the IP address field 66.51.120.17 then
click create.


www.mt-orthopedic-surgeons.com. IN A

ANSWER SECTION:

www.mt-orthopedic-surgeons.com. 3600 IN A 66.51.120.17

If you want to access by mt-orthopedic-surgeons.com without the www that is
another situation that is not so easy to do. If you are interested, let me
know and I'll give you the process.

That worked....you're brilliant! Thanks.

I'm not sure what the problem was creating the www record, since you're
saying it didn't work, but yet when Kevin gave you the steps, it worked?
Were you creating it incorrectly the first time?
