Active Directory: installation and configuration of a domain controller

In this tutorial, we will see how to set up an Active Directory domain by installing the first domain controller.

In summary, an Active Directory environment is a directory in the form of a database (LDAP) which contains a set of objects (users, computers, etc.) and which delivers several services:

  • Centralization of objects on the network in a single database
  • User Authentication
  • Rights management
  • Policy Application (GPO)

The AD architecture is based on:

  • Domain: which can be registered or not.
  • Tree: consisting of a domain and subdomain (child domain)
  • Forest: consisting of linked trees with an approval relationship.
  • Global Catalog: A domain controller that contains information about the entire forest.
  • FSMO role that are 5 in number.

In this tutorial, we will create a forest with a tree made up of the lab.lan domain.

What you need to complete this tutorial:

  • A Windows server (2012 / 2012R2 / 2016) with a fixed IP address
  • A client (Windows 7 or +) with an IP address, it must also have how server dns Windows server.

According to Microsoft best practices, it is recommended that you have at least 2 domain controllers (global catalog) per domain.
