Internet and intranet domain name - problem with dns!

[vtube]

I have a problem: I have win2000 server active directory with a domain
name "dummy.com".
The problem is... I choose the same name for the Internet domain
(hosted by a provider): "www.dummy.com".

I have no problem in the intranet, but when I pin pop3.dummy.com
(should be on the Internet), the I have "unknown host" error message: I
think that the dns server haven't any info about host pop3 in the
intranet, and answer error.

I need to tell to dns server on win 2000 to forward to the internet any
request about "pop3.dummy.com" and not to solve locally.

"pop3.dummy.com" hasn't got a fixed IP, is managed by my provider.

Many thanks if someone can help me!

Either:
1. Throw out the old and create a new AD Domain
or
2. Run Split-DNS
or
3. as a last hope,...use Hosts files on all the machines to correct the
resolution.

Thanks for your reply!

No. 1 is the hardest: I need so much time backing up all PCs,
destroying current AD and creating a new one. The last option.

No. 2: I'll search for some info... Have you any hints?

No. 3: the problem is that the pop3 public server hasn't a fixed IP!

Just do a search for "Split DNS" or "Split-DNS". I have nothing that would
directly apply to your situation.

No. 3: the problem is that the pop3 public server hasn't a fixed IP!

Then you are screwed. That has to be corrected,..it needs to be a fixed
IP#. As far as your clients are concerned your internal AD DNS is
"authoritative" for the domian name (not the ISP), and your AD/DNS cannot
deal with the dynamic IP# from the ISP.
If that can't be made static,..then you have to do "No. 1".

This kind of trouble is why a person has to reseach everything before the AD
Domain is created. And you also have to research all the ramifications of
getting an ISP that uses dynamic IP#s before you give them any $$$.

Phil's Rules:
1. AD Domains are not the same thing as Public Domains,...have nothing to do
with each other,... exist for entirely different reasons,...and should never
be the same name.
2. Never except dynamic IPs from an ISP for a commecial network. Dynamic
IP#s are for Home Users.

Thanks Philip!

We have a fixed IP for the web server, not for the POP3 server.

You need one for both.
