Using internet domain name in local network

We have a win2003 server in our local network and we use this server to host
our web portal that writen with c# asp.net for internet and intranet
Environments.
The local name of this web server on our network is "WebServerPortal".
if we use WebSerberPortal in web browsers address bar like
http://webserverportal it works fine for local network(intranet) users but
the internet domain name does not work.
I mean if i write "http://www.companyname.com" to web browser in local
network, an authorization forms appears and ask for username and password.
And there is an expression on that form, it says
----------------------------------------------
The server companyname.com at USR ADSL Gateway requires a username and
password.

Warning: This server is requesting that your username and password be sent
in an insecure manner (basic authentication without a secure connection).
----------------------------------------------
But from the internet the domain name "http://www.companyname.com" works
fine.

How can we use our internet domain name(www.companyname.com) in local
network ?

Thanks in advance..


PS: http://www.companyname.com is a sample name.

Assuming your active directory domain name is companyname.com, you need to
make a DNS entry for "www" that points to the internal address of your
webserver.

You have to run Split-DNS. In Split-DNS your AD/DNS Server will have two
Zones
Zone #1 = AD Domain name
Zone #2 = Public Domain Name

Configure the Public Domain Zone's host records with the proper IP#. The
Public Zone is not dynamically updated. You have to maintain it yourself.
