70-742 Certification: Managing Identities in Windows Server 

Active Directory Domain Services (AD DS) is the foundational identity and access management system in Windows Server 2016. It enables centralized administration of users, computers, and other resources across a network. AD DS provides a structured hierarchy to manage objects and facilitates authentication, authorization, and policy enforcement. Understanding the architecture of AD DS is critical for planning and maintaining a secure, scalable network environment.

AD DS organizes resources into domains, trees, and forests. A domain serves as the core administrative boundary for user and computer accounts, security policies, and access permissions. Multiple domains can form a tree structure that shares a contiguous namespace, while a forest represents the highest level of the directory hierarchy, encompassing multiple domain trees. Forests allow separate domains to maintain distinct policies while enabling trust relationships and replication across the network.

Installing and Configuring Domain Controllers

A domain controller is the server responsible for hosting AD DS and providing authentication services for users and computers. Installing a domain controller involves several steps that include preparing the server, configuring networking, and promoting the server to a domain controller. A new forest installation requires planning the namespace, defining the forest and domain functional levels, and configuring DNS integration. Properly deploying domain controllers ensures that authentication requests are efficiently handled and that directory replication functions correctly.

Adding a new domain controller to an existing domain involves replicating directory data from an existing controller. This replication ensures consistency of account information and security settings across the environment. When upgrading a domain controller, careful attention must be given to maintaining replication, functional levels, and service continuity. Server Core installations of domain controllers offer a lightweight deployment option, minimizing the operating system footprint and reducing attack surfaces while still providing full AD DS functionality.

Domain Controller Operations and Maintenance

Managing domain controllers requires understanding key operational tasks. Transferring and seizing operations master roles, also known as FSMO roles, is crucial for maintaining directory consistency and availability. Each FSMO role provides specialized functions, such as managing schema updates or controlling group membership, and must be assigned strategically within the network.

Configuring a global catalog server enables efficient search operations and logon processes across multiple domains. The global catalog contains a partial replica of all objects in the forest, allowing users to locate resources without querying every domain controller. Read-only domain controllers provide additional security by preventing unauthorized changes while still offering authentication services in branch offices or untrusted environments. Domain controller cloning can simplify deployment and reduce the time required to provision additional servers, but it requires careful preparation of virtual machines and permissions.

DNS Integration and Directory Services

AD DS relies heavily on the Domain Name System (DNS) for locating services and resources. Proper DNS configuration ensures that clients can find domain controllers and that replication occurs without interruption. DNS SRV records are critical for service discovery, and issues with registration or replication can disrupt authentication and policy application. Administrators must understand how to resolve these issues and maintain a healthy DNS infrastructure.

Sites and subnets are logical constructs that represent the physical topology of the network. Configuring sites allows administrators to control replication traffic, optimize authentication, and manage client access to nearby domain controllers. Site links define the connections between sites and influence replication schedules and costs. Moving domain controllers between sites or configuring site coverage requires careful planning to avoid authentication delays or replication conflicts.

Active Directory Deployment Strategies

Planning for large or complex deployments involves understanding multi-domain and multi-forest environments. Multi-domain architectures provide administrative boundaries, while multi-forest architectures support organizations with separate security policies or regulatory requirements. Upgrading existing domains and forests requires assessing the current functional levels and ensuring compatibility with new features. External, forest, shortcut, and realm trusts enable collaboration between distinct Active Directory environments and other directory services, allowing for seamless authentication and resource access.

Trust relationships involve careful configuration to balance security and accessibility. Trust authentication, SID filtering, and name suffix routing are all components that determine how users from one domain or forest can access resources in another. Administrators must design trust topologies to prevent unauthorized access while maintaining operational efficiency. Proper monitoring and management of Active Directory replication and trust health are essential for a robust identity infrastructure.

Managing Active Directory Users

Active Directory users are the core entities that represent people or services within a domain. Effective management of user accounts is essential for security, access control, and compliance. Creating users involves assigning unique attributes such as usernames, security identifiers, and group memberships. Administrators must also consider account lifecycle management, including enabling, disabling, and deleting accounts as organizational needs change.

Automating user account creation can significantly reduce administrative overhead. PowerShell scripts and templates allow for bulk provisioning, ensuring consistency in attribute assignment and group memberships. Templates standardize account settings such as password policies, department attributes, and home directories, providing uniformity across the organization. Automating account maintenance tasks, including password resets and account unlocking, reduces helpdesk workload and enhances user productivity.

Managing inactive or disabled accounts is critical for security. Accounts that are no longer in use can become targets for unauthorized access. Implementing policies for automatic detection, review, and removal of inactive accounts helps mitigate risk. Tools such as Windows PowerShell allow administrators to identify and manage these accounts efficiently, applying consistent rules and processes across the domain.

Groups and Organizational Units

Groups in Active Directory provide a way to organize users and assign permissions collectively. Groups can be security groups, used to assign access to resources, or distribution groups, used for email distribution. Group types include domain local, global, and universal, each with specific use cases and scope limitations. Understanding the differences and correctly nesting groups ensures that access is properly controlled and scalable.

Organizational Units (OUs) are containers that allow administrators to group users, computers, and other objects for delegation, policy application, and administrative management. OUs provide a logical structure within a domain without affecting the namespace. Delegating control over OUs allows administrators to assign specific management tasks to lower-level administrators or teams without granting full domain-wide privileges.

Group membership management can be automated using PowerShell, enabling administrators to add or remove users dynamically based on attributes or organizational changes. Properly planning group structure, membership rules, and nesting strategies ensures efficient administration and reduces the risk of privilege creep, where users accumulate excessive permissions over time.

Account Policies and Authentication

Active Directory provides mechanisms to enforce account and password policies across the domain. Service accounts, including managed and group-managed service accounts, are specialized accounts designed to run services and applications securely. Kerberos Constrained Delegation (KCD) allows specific services to act on behalf of users while maintaining security constraints. Service Principal Names (SPNs) must be properly configured to ensure Kerberos authentication works correctly for services.

Virtual accounts and managed service accounts simplify password management and enhance security by automatically rotating credentials. Password policies, including complexity requirements and expiration, enforce organizational standards and reduce the risk of unauthorized access. Password Settings Objects (PSOs) allow for fine-grained password and account lockout policies for specific users or groups, providing flexibility beyond default domain policies.

Delegating password and account management tasks improves operational efficiency. For example, certain administrators may be allowed to reset passwords or unlock accounts for a subset of users without having full control over the domain. These delegations reduce bottlenecks while maintaining security and accountability.

Maintaining Active Directory Objects

Maintaining Active Directory (AD) objects is a critical responsibility for administrators to ensure the integrity, performance, and security of the domain environment. AD objects include users, groups, computers, organizational units (OUs), and other directory components. Proper maintenance ensures that these objects reflect the current organizational structure, comply with policies, and support operational efficiency.

One of the foundational aspects of maintaining AD objects is ensuring accurate and up-to-date user and computer accounts. This involves creating accounts following naming conventions, assigning appropriate group memberships, and applying security policies consistently. Administrators should regularly review accounts to identify inactive, disabled, or obsolete users and computers. Automated tools and PowerShell scripts can assist in detecting stale accounts, which is crucial for minimizing potential security risks associated with unused credentials. Removing or disabling inactive accounts reduces the attack surface and helps maintain an organized directory structure.

Group management is another core component of object maintenance. Groups are used to simplify permissions assignment, enforce policies, and facilitate collaboration. Administrators must regularly review group memberships to ensure that users have appropriate access and that security groups are not overpopulated or misconfigured. Converting groups between types—such as from global to universal—or nesting groups requires careful planning to avoid access conflicts or replication issues. Delegating group management to designated personnel can improve efficiency, but it requires clearly defined roles and monitoring to prevent unauthorized changes.

Organizational units (OUs) provide a hierarchical structure for grouping objects and applying Group Policy Objects (GPOs). Maintaining OUs involves ensuring that they are logically structured, aligned with business units or functional areas, and optimized for policy application. Administrators should periodically assess whether objects are placed in the correct OUs and whether GPOs linked to these OUs are effective and relevant. Misaligned OUs can result in policy misapplication, administrative confusion, and inconsistent access control, making regular review essential.

Password and account policies play a key role in AD object maintenance. Configuring Password Settings Objects (PSOs) and enforcing Kerberos policies ensures that account security standards are met across the organization. Administrators must monitor for repeated lockouts, enforce complex password requirements, and ensure proper delegation of password reset rights. Automating account unlocks and password resets via PowerShell not only improves efficiency but also reduces the risk of human error.

Backup and recovery are crucial aspects of maintaining AD objects. Regularly backing up the Active Directory database and SYSVOL ensures that administrators can restore objects or entire domains in case of corruption, accidental deletion, or hardware failure. Features such as the Active Directory Recycle Bin and object-level recovery allow selective restoration of users, groups, or OUs without performing a full restore, reducing downtime and operational disruption. Performing offline defragmentation and monitoring replication health are also part of proactive maintenance, helping to maintain directory performance and prevent replication conflicts between domain controllers.

Delegation and auditing complement these practices. Assigning specific administrative rights for object management ensures that responsibilities are distributed and reduces the likelihood of accidental or malicious changes. Auditing object modifications, logins, and deletions allows administrators to track changes, detect anomalies, and maintain compliance with regulatory requirements. Regularly reviewing audit logs and security events helps identify potential issues early, enabling corrective action before problems escalate.

Finally, automation and scripting are indispensable for large-scale environments. Routine tasks such as bulk account creation, group membership adjustments, and OU restructuring can be automated using PowerShell or other management tools. This ensures consistency, reduces manual errors, and frees administrators to focus on higher-level tasks such as security planning, policy design, and infrastructure optimization.

Maintaining Active Directory objects is not a one-time effort; it is an ongoing process that demands diligence, planning, and proactive management. By combining best practices in account management, group and OU organization, security policy enforcement, backup and recovery, delegation, auditing, and automation, administrators can ensure that AD remains secure, efficient, and aligned with organizational objectives. This continuous attention safeguards the integrity of the directory, enhances operational reliability, and supports the broader goals of enterprise identity management.

Introduction to Group Policy

Group Policy is a core feature of Windows Server 2016 that enables centralized management of operating system, application, and user settings across an Active Directory environment. By applying Group Policy Objects (GPOs), administrators can enforce security settings, deploy software, and configure desktop environments consistently across users and computers. Understanding how Group Policy works conceptually is essential to designing scalable and maintainable management strategies.

Group Policy operates within the context of Active Directory’s logical structure, applying settings based on site, domain, and organizational unit hierarchy. The order of processing—local, site, domain, and OU—determines how conflicts are resolved. Administrators must consider inheritance, precedence, and enforcement when designing policies to ensure predictable behavior. Tools such as the Group Policy Management Console provide a centralized interface to create, link, and monitor GPOs.

Creating and Managing Group Policy Objects

Creating a Group Policy Object involves defining a container for policy settings and linking it to the appropriate scope, such as an OU, domain, or site. Each GPO contains settings for software deployment, security configuration, scripts, folder redirection, and administrative templates. Group Policy preferences extend configuration options to include items like mapped drives, printer connections, and custom registry settings.

Administrators can manage starter GPOs, which serve as templates for creating new policies with predefined settings. Central stores for administrative templates ensure consistency across the enterprise and simplify the deployment of new GPOs. Backing up, importing, copying, and restoring GPOs provides flexibility when migrating settings between environments or recovering from accidental changes. Migration tables allow for precise adaptation of GPOs when moving them between domains with different paths or names.

Delegation of Group Policy management enables multiple administrators to manage GPOs without granting full domain rights. By carefully assigning permissions, organizations can maintain operational efficiency while protecting critical settings. Monitoring Group Policy infrastructure, using dashboards and event logs, ensures that policies are applied correctly and helps detect misconfigurations or replication issues.

Configuring Group Policy Processing

Group Policy processing determines how settings are applied to users and computers. Administrators can configure the processing order and precedence to ensure that critical policies take priority. Blocking inheritance and enforcing policies provide additional control over which GPOs affect specific objects. Security filtering and Windows Management Instrumentation (WMI) filtering allow policies to target specific users, groups, or devices based on attributes, reducing the risk of misapplied settings.

Loopback processing modifies the standard behavior of Group Policy, applying user settings based on the computer they log onto rather than their account location. This is particularly useful in shared environments, such as classrooms or kiosks, where user-specific settings must be overridden. Slow-link processing and Group Policy caching help maintain performance and usability for remote users with limited network connectivity, ensuring that policies are applied efficiently even under suboptimal conditions.

Client-side extensions interpret and apply policy settings on each computer. Administrators can force policy updates to ensure that changes take effect promptly and can configure the behavior of scripts, software installation, and other settings to align with organizational requirements. Understanding the interplay between these components ensures that Group Policy remains a reliable and powerful tool for enterprise management.

Implementing Specific Group Policy Settings

Group Policy settings encompass security, system, and user configuration options. Software installation through GPOs allows administrators to deploy applications automatically or make them available for self-service installation. Folder redirection centralizes user data on network shares, improving backup and access management while ensuring consistent user experiences. Scripts can automate repetitive tasks, from logon and logoff to system maintenance operations.

Administrative templates provide fine-grained control over system and application behavior, including custom registry settings, Control Panel restrictions, Internet Explorer configuration, and power management. Group Policy preferences expand flexibility, enabling configuration of network drives, printers, shortcuts, and other environment settings without enforcing strict restrictions. Item-level targeting ensures that policies apply only to specific users or devices based on criteria such as security group membership, operating system version, or IP address.

By designing Group Policy strategies that balance security, functionality, and administrative efficiency, organizations can maintain a controlled and consistent computing environment. Proper monitoring, planning, and documentation of policies prevent conflicts and ensure that changes scale effectively as the organization grows.

Implementing Active Directory Certificate Services

Active Directory Certificate Services (AD CS) provides a framework for issuing and managing digital certificates within an enterprise. Certificates support authentication, encryption, and integrity for users, devices, and applications. Installing and configuring AD CS requires careful planning of the hierarchy, including root and subordinate Certificate Authorities (CAs), as well as understanding the differences between enterprise-integrated and standalone CAs.

Certificate Revocation Lists (CRLs) ensure that invalid or compromised certificates are recognized and rejected. Properly configuring CRL distribution points and Online Responder services is crucial for maintaining trust and preventing security breaches. Administrative role separation allows organizations to distribute responsibilities across multiple personnel, enhancing security by reducing the risk of insider compromise.

Managing certificates includes issuance, renewal, validation, and revocation. Group Policies can enforce automatic certificate enrollment for users and computers, simplifying deployment while maintaining security compliance. Key archival and recovery mechanisms protect against data loss, ensuring that encrypted data remains accessible even if keys are lost or users leave the organization.

Active Directory Federation Services

Active Directory Federation Services (AD FS) provides single sign-on and claims-based authentication across organizational boundaries. It allows users to access applications and services using a single set of credentials, even when resources reside outside the corporate network. AD FS supports integration with Microsoft Passport, Azure services, Office 365, and third-party applications.

Configuring AD FS involves establishing trust relationships, creating Relying Party Trusts, and defining claims rules that determine how authentication attributes are presented. Multi-factor authentication policies enhance security by requiring additional verification steps for sensitive resources. Device registration enables secure access for managed devices while enforcing conditional access policies.

Migrating previous AD FS workloads to Windows Server 2016 requires careful planning to maintain trust relationships, claims rules, and authentication policies. Maintaining and monitoring AD FS health ensures reliable access for users, with tools available to troubleshoot token issuance, authentication failures, and replication issues across federation servers.

Web Application Proxy

Web Application Proxy (WAP) extends AD FS capabilities by publishing internal applications to external users while maintaining security. WAP can operate in pass-through mode, forwarding authentication requests to AD FS, or as a proxy, providing additional layers of inspection and security for published applications.

Configuring WAP requires careful consideration of network topology, SSL certificates, internal and external Fully Qualified Domain Names (FQDNs), and HTTP to HTTPS redirection. Publishing applications such as web portals or Remote Desktop Gateway services involves defining access rules, authentication requirements, and secure channel configurations. Properly integrating WAP with AD FS ensures that external users can authenticate securely without exposing the internal infrastructure directly.

Active Directory Rights Management Services

Active Directory Rights Management Services (AD RMS) provides data protection by enforcing usage policies on sensitive content. It enables organizations to control who can access, edit, print, or forward documents and emails, maintaining confidentiality even outside the corporate network.

Installing AD RMS involves configuring a licensor certificate, deploying the server role, and managing Service Connection Points (SCPs) that allow clients to discover AD RMS services. Administrators define templates that specify usage rights, and exclusion policies can be applied to prevent conflicts or unintended restrictions. Backup and restore processes ensure continuity of protection and maintain recoverability for protected content in case of server failure or migration.

AD RMS integrates with client applications and enterprise services to enforce rights consistently. Administrators must plan for scalability, high availability, and certificate management to ensure that protections remain effective across diverse environments and geographies.
