Domain Name in Active Directory setup?

[Avery]

I'm brand new at Active Directory and DNS. I'm a bit unclear as to
what to enter for a domain name during the initial Active Directory
setup.

I've already got a domain name for my website...example.com set up and
currently the website is hosted elsewhere and has been for years.
During AD setup, I entered the name of my website, example.com, as the
domain name, and AD setup completed along with the DNS setup. On a
client machine, I change the primary DNS server to point to my server,
upon which I just installed DNS and AD. I was able to browse the
internet successfully, but was not able to browse to my website,
example.com. Could it be because I used that name during AD setup?
According to the setup, it's ok to do that. I'm obviously missing a
step or still am unclear on something.

Any ideas would be great! Thanks in advance...

Since you are using the same domain name for your Active Directory name you will need
to add a static record for the ip address of your website. Your AD clients will not
look any further that your AD dc dns server since it is authoritative for that domain
as far as they know. This is known as "split brain" dns. --- Steve

You better would have called your AD-domain something like example.local.
You can't change that anymore, it would need a reinstall, so you'll need to
add a hostrecord to your DNS-server pointing to your public IP on your
website.
