If you are applying a single domain model, the single domain functions as the forest root domain. If you are applying a multiple domain model, you can choose to deploy a dedicated forest root domain or select a regional domain to function as the forest root domain.
A dedicated forest root domain is a domain that is created specifically to function as the forest root. It does not contain any user accounts other than the service administrator accounts for the forest root domain. Also, it does not represent any geographical region in your domain structure.
All other domains in the forest are children of the dedicated forest root domain. In a multiple-regional-domain environment in which a dedicated forest root is used, the replication of the forest root domain has minimal impact on the network infrastructure.
This is because the forest root only hosts the service administrator accounts. The majority of the user accounts in the forest and other domain-specific data are stored in the regional domains. One disadvantage to using a dedicated forest root domain is that it creates additional management overhead to support the additional domain.
If you choose not to deploy a dedicated forest root domain, you must select a regional domain to function as the forest root domain. This domain is the parent domain of all of the other regional domains and will be the first domain that you deploy.
The forest root domain contains user accounts and is managed in the same way that the other regional domains are managed. The primary difference is that it also includes the Enterprise Admins and Schema Admins groups.
The advantage of selecting a regional domain to function as the forest root domain is that it does not create the additional management overhead that maintaining an additional domain creates. In this example,. This is similar to the root directory on a typical workstation, where all other directories or folders originate. Within the. The same applies to web addresses. For example, www.
In this case, is my domain controller exposed on the internet? Is the only ways of protecting my domain controller from the internet through not having a physical connection to the internet or a firewall, or is it settings inside Windows Server?
It depends on your network setup; usually, a router performs NAT for your internal network, thus your computers are unreachable from the outside unless you explicitly publish something. However, this is getting quickly out of scope, and it's better suited for a different question. Show 1 more comment. Sign up or log in Sign up using Google. Sign up using Facebook.

Connect and share knowledge within a single location that is structured and easy to search. A forest is a collection of domains.
When you create a new domain, you choose whether to make it the root domain of a new forest, or to make it part of an existing forest. The forest name is the DNS name of the root domain of the forest, i. So the forest name and the DNS name will be the same if and only if the domain is the forest root domain.
In answer to your third question: The DNS name is the name of your domain. The forest name is, of course, the name of your forest! According to TechNet , your forest name should not be the same as any existing domain name, so that there won't be any conflicts that require you to modify your existing DNS infrastructure. The convention suggested is choosing a suffix from an existing DNS name and adding a unique prefix to it to create a unique namespace. To understand what a forest name is, you need to understand what forests, trees, and domains are in Active Directory.
