In Windows Server 2011 it is called Active Directory.
Active Directory was previewed in 1999, released first with Windows 2000 Server edition, and revised to extend functionality and improve administration in Windows Server 2003. Additional improvements were made in Windows Server 2003 R2. Active Directory was refined further in Windows Server 2008 and Windows Server 2008 R2 and was renamed Active Directory Domain Services. Active Directory was called NTDS (NT Directory Service) in older Microsoft documents. This name can still be seen in some Active Directory binaries.

To install Active Directory on a Windows Server, a proper DNS (Domain Name System) name resolution is required. The server must have a DNS server configured, as Active Directory relies on DNS for locating domain controllers and other resources within the domain. It's essential that the server can resolve its own name and the names of other domain controllers in the environment. Additionally, the DNS zone for the domain should be properly set up to facilitate name resolution.
Just run 'dcpromo'.
