Computers within domain cannot find agency's own website

Posted on 2011-05-09

We just setup a 2008R2 Domain Controller with Active Directory Domain Services, DNS Server and DHCP Server.
When going through the setup wizard for the AD DS role, we set the FQDN of the new forest root domain as ""
After we were done, it seemed that everything was OK: you could resolve any internal address and you could go out to any external webpage, but we found out a little later that we could not access our own website "" (externally hosted).
Any help will be greatly appreciated.

    1. Open the DNS Console
    2. Expand Forward Lookup Zones
    3. Select
    4. Right click and add a new Host (A) record
    5. Enter "www" in the Name
    6. Enter the public IP of your site

    On a client (a PC or something), run:

    ipconfig /flushdns

    Then browse to the site. You'll be able to use:

    But not:
