• Active Directory Administrative Center: Introduced in Windows Server 2008 R2, this tool provides a modern and more intuitive interface for managing Active Directory. It offers additional features such as fine-grained password policies and dynamic access control, making it a preferred choice for many administrators.
• Active Directory Sites and Services: This tool is used to manage the replication topology of Active Directory across different sites. It allows administrators to define site links, assign domain controllers to sites, and monitor the replication status. It has been a part of Windows Server since the early versions of Active Directory.
• Active Directory Domains and Trusts: This tool is used to manage trust relationships between domains in a forest. It allows administrators to create, modify, and delete trusts, which are essential for establishing secure communication and resource sharing between different domains. It has been a part of Windows Server since the introduction of Active Directory.
• Active Directory Federation Services (ADFS): ADFS is a feature of Windows Server that provides single sign-on access to web-based applications within an organization. It enables users to authenticate using their Active Directory credentials and access multiple applications without having to provide separate login credentials for each application.
• Active Directory Lightweight Directory Services (AD LDS): AD LDS is a lightweight version of Active Directory that can be used to provide directory services for applications that require a flexible and extensible directory structure. It was introduced in Windows Server 2008 and is commonly used in scenarios such as application development and identity management.
• Active Directory Certificate Services (AD CS): AD CS is a role in Windows Server that allows organizations to deploy and manage public key infrastructure (PKI) certificates. It enables the issuance, revocation, and management of digital certificates for various purposes such as secure email communication, SSL/TLS encryption, and code signing.
• Active Directory Rights Management Services (AD RMS): AD RMS is a role in Windows Server that provides information protection by encrypting and restricting access to sensitive documents and emails. It allows organizations to define policies for controlling the usage, copying, and distribution of protected content.

Cases when Active Directory does not work

1. Network connectivity issues: Active Directory heavily relies on network connectivity for its proper functioning. If there are any issues with the network, such as slow or intermittent connections, it can lead to Active Directory not working correctly. This can manifest in various ways, including difficulty in authenticating users, replication failures, or inability to locate domain controllers.
2. Hardware failures: Active Directory depends on the underlying hardware infrastructure to operate efficiently. If there are hardware failures, such as a faulty disk drive, power supply, or network card, it can cause Active Directory to malfunction. This can result in services being unavailable, data corruption, or even complete system failures.
3. Software misconfigurations: Incorrect configurations within Active Directory or related software components can lead to its failure. Misconfigurations can occur during initial setup, routine maintenance, or when making changes to the system. Common misconfigurations that can cause issues include incorrect DNS settings, time synchronization problems, or improper firewall rules.
4. Security breaches: Security breaches, such as unauthorized access or malware infections, can severely impact the functionality of Active Directory. Attackers may gain control over domain controllers, compromise user accounts, or alter critical settings, leading to disruptions in service and compromising the integrity of the directory.
5. Domain controller failures: Active Directory relies on domain controllers to store and replicate directory information. If a domain controller fails or becomes unresponsive, it can affect the availability and performance of Active Directory services. In such cases, other domain controllers may need to take over the failed controller’s responsibilities to ensure continuity of operations.
6. Data corruption or loss: Active Directory databases store critical information about users, groups, and other directory objects. If the database becomes corrupted or experiences data loss due to hardware failures, software bugs, or other factors, Active Directory may not function properly. Data corruption can lead to authentication issues, replication failures, or inconsistencies in directory information.
7. Insufficient resources: Active Directory requires sufficient resources, including CPU, memory, and disk space, to operate efficiently. If the system is under-provisioned or resources are exhausted due to high usage, Active Directory performance can degrade or even result in service disruptions. Insufficient resources can also impact the ability to perform tasks such as replication, authentication, and group policy processing.
