DNS subdomain delegation in Windows 2003

[Do]

Hi:

I have a Win2k3 AD domain with the name domain.com.
My Internet site is also the same domain.com.

What do I do to forward any local area network requests
of www.domain.com to my Internet website and not my internal
network?

Thanks,

Do

Method 1. In your internal zone for domain.com create a new host named www,
give it the IP address of the website.
Method 2. In your internal zone for domain.com create a delegation named
www, give it the host name and IP address of the public Authoritative DNS
servers. The delegation must be to the Authoritative DNS servers. One note,
if the public DNS has a CNAME for the www record you DNS server must also be
able to resolve the host the CNAME points to. You need to run nslookup
against the authoritative DNS to verify the www record exists as an "A" host
or a CNAME.

Hi,

I 've added the delegation and the ping seems to go to the right external IP
address.

However, when I open my browser and try to browse with just
http://www.domain.com , it doesn't resolve. Seems like www resolves locally.
But when I open the browser and browse with the domain name and a path (e.g.
http://www.domain.com/default.asp, then it works.

Any suggestions?

Is the problem that it doesn't resolve or IE is unable to connect? Try accessing the website by IP address. Does this work? If not, verify that the IP address
you are connecting to isn't the IP address of the external adapter on your firewall. If this is, some firewalls will block this as a spoof attack.

Thank you,
