How to Install and Set Up Active Directory on Windows Server

Active Directory (AD) is a database and set of services that connect users with the network resources they need to get their work done. The database, or directory, contains critical information about your environment, including what users and computers there are and who’s allowed to do what. For example, the database might list 100 user accounts with details like each person’s job title, phone number, and password. It’ll also record their permissions.
