Active Directory is a database used for storing information about users, computers, and network resources. Using AD integrated services allow systems administrators to centrally manage network resources and security policies on large networks.
In order to use Active Directory, the Active Directory Domain Controller role needs to be installed. It’s recommended to install it on at least two servers for fault tolerance. Each Domain Controller runs three main services. LDAP is a directory service used for storing information like usernames and passwords. Kerberos is an authentication service used to login. And DNS is used to resolve hostnames to IP addresses.
To begin, run dcpromo. Follow the steps in the setup wizard. Create a new domain in a new forest and reboot when it finishes. For management purposes and to help delegate responsibilities, objects in Active Directory can be organized into Organizational Units. To manage OUs, click the Start menu, click Administrative tools, click Active Directory Users and Computers.
To use Active Directory, client computers will need to be joined to the domain. Make sure the DNS server settings are configured to point to the domain controller. Open Windows Explorer, right click on Computer, click Properties, click Change Settings, add computer and domain name, and click Add. Provide admin credentials when prompted, then reboot.
Group Policy allows you to have separate policies for different groups of computers. From the Start menu, browse to Administrative Tools and open the Group Policy Management Editor. Create a new GPO and link it to the domain or the OU containing the user and computer accounts.
