What is Active Directory? Active Directory is a database that keeps track of all the user accounts and passwords in your organization. It allows you to store your user accounts and passwords in one protected location, improving your organization's security. Active Directory is subdivided into one or more domains. A domain is a security boundary. Each domain is hosted by a server computer called a domain controller (DC). A domain controller manages all of the user accounts and passwords for a domain. Domains and the Domain Name System (DNS) Domains are named using the Domain Name System (DNS).
