Continuation of Active Directory…
Active Directory Domain Services (AD DS)
There is no role called Domain Controller. The role that provides all of these capabilities is called Active Directory Domain Services or AD DS. By installing that role, you will have turned your server into a domain controller.
The purpose of DC is to create a directory or database of objects in your network. This database is known as Active Directory and is a platform inside which you build a hierarchical structure to store objects, such as usernames, passwords and computer accounts.
There is a whole hierarchy within an Active Directory schema, comprised of forests, trees, domains and organizational units.
One of the first things that needs to be decided before you can build a domain is the name of the domain. Everyone uses DNS every day whether they realize it or not. For example microsoft.com, is the primary domain name also known as a domain suffix or a top-level domain.
There are three simple things that need to happen on any sever that you plan to turn into a domain controller:
1. Set a static IP address
2. Set a good hostname
3. Set the DNS server address
