Active Directory is a technology created by Microsoft that provides a way to manage computer networks. Active Directory is used to store information on user accounts, computers, printers, groups, mailing lists, security information and more. This information can be replicated and synchronized between additional Active Directory servers. Active Directory can also be used to apply policies to PC's, deploy software and install updates.
Active Directory was first introduced with Windows Server 2000, and has been improved on with Windows Server 2003 and 2008.
