Study Notes
Active Directory Directory Services
- Active Directory is a directory service that allows you to manage users, computers, and other network resources.
- The process of granting a user access only to the resources they are permitted to use is called authorization.
- Authentication allows you to check a user's identity against a database and allows them to access the network.
- LDAP (Lightweight Directory Access Protocol) defines the format of the queries that Active Directory clients send to domain controllers.
- The basic classes of Active Directory objects are container objects and leaf objects.
- Container objects include domains and organizational units.
- Leaf objects represent individual users, computers, and resources.
- The Active Directory schema defines the structure of the directory.
- This includes what objects exist and what attributes are associated with each object.
- Organizational Units (OUs) are the next level of container objects under a domain.
- OUs are used to organize users and computers into logical groups and they inherit policies and permissions from their parent objects.
- Active Directory has a naming convention that mirrors the DNS (Domain Name System).
- Bidirectional trust relationships between domains allow users in one domain to access resources in another domain within the same domain tree.
- Multiple-master replication minimizes problems in database management over slow WAN links (Wide Area Network).
- Each domain controller in a domain replicates its database to other controllers, allowing for changes to be synchronized.
- Domain controllers must be registered in DNS for computers on the network to be able to find them.
Installing Domain Controllers
- Domain controllers can be installed using the Add Roles and Features Wizard in Server Manager.
- Installation requires you to configure the DNS server and supply the password for Directory Services Restore Mode (DSRM).
- You can also use PowerShell to install domain controllers.
- The cmdlet Install-AddsDomainController is used to install a domain controller to an existing domain.
- The cmdlet Install-AddsForest is used to create a new forest.
- To remove a domain controller, you can use the Remove Roles and Features Wizard in Server Manager.
- To demote a domain controller, you can use the Uninstall-ADDSDomainController PowerShell cmdlet.
Active Directory Sites
- An Active Directory site is a collection of subnets with good connectivity.
- This helps ensure that the replication process is efficient between domain controllers.
- Sites are created to control the traffic passing over slow WAN links.
- The site topology is manually configured based on WAN bandwidth and transmission speed.
- Sites provide a geographical division within the Active Directory network.
Functional Levels
- The functional level of an Active Directory forest determines which features are supported by the forest.
- The functional level is determined by the lowest version of Windows Server running on any of the domain controllers in the forest.
- You can upgrade the functional level of a forest by upgrading the domain controllers to a newer version of Windows Server.
- The global catalog is an index of all objects in an Active Directory forest.
- Clients use the global catalog to find objects that are not in their local domain.
Important Considerations
- Groups are used to organize users and computers for security purposes.
- Groups have no hierarchical association with the domain's tree structure.
- OUs are used to organize users and computers into logical groups based on the structure of your organization.
- OUs inherit policies and permissions from their parent objects.
- To confirm if a domain controller has been registered in the DNS, you can use the dcdiag /test:registerindns /dnsdomain:\ /v command.
- The SRV resource record enables clients to locate domain controllers and other vital AD DS services.
Managing Active Directory
- Windows Intune and Azure are cloud-based solutions that can be used to manage Active Directory.
- Office 365 is a cloud-based suite of applications that can be integrated with Active Directory.
