Hi,
I want to use my internet domain name as my Win2k domain
name too. How do I configure DNS to accomplish this? Do
I need to configure DNS "shadowing"? Is this a valid
approach?
Thanks,
Bill

This is called a Split Horizon method. No problem.

Assuming that your external domain is hosted by your ISP or registrar (not
by you), then easy, no shadowing required. Just manually create www, ftp and
mail records (and whatever other records you need to get to on the outside)
under your DNS server's zone, and give those records their coorespinding
actual external IP addresses.

If you want to get to http://yourdomain.com, (without www), then that
requires a reg entry and a manual blank host record created (called the
LdapIpAddress). But most folks are cool with the www only method.

If you are hosting your external names, then you would need separate DNS
server(s) just for that.

Don't forget, all machines in an AD environment ONLY use your internal DNS
and configure a forwarder for efficient Internet name resolution.

Yes , it is valid many people use it. It is a pretty simple approach as long
as you don't get the urge to host your public DNS zone for your domain.
All internal clients and servers MUST use the internal DNS ONLY in TCP/IP
properties. Then all you need to do is add the missing public hosts such as
www and mail to the internal domain. That is pretty much the just of it.
