Domain and Architectural Design
A highly available topology is designed by determining the namespace, Forest/Domain hierarchy, Active Directory Sites & Services, and integrated DNS infrastructure requirements.
Active Directory setup is a service that involves the end-to-end design and deployment of Microsoft Active Directory Domain Services (AD DS) and related services to centrally manage user, computer, group, and authorization matrices within an enterprise network.
The infrastructure security and authorization standards of modern corporations are built on a centralized identity architecture. During the Active Directory setup process, a comprehensive directory service architecture that meets the organization's scalability, security, and access needs is not limited to activating a single Domain Controller (DC); it is designed holistically.
The process includes configuring the Forest/Domain hierarchy, DNS infrastructure, Organizational Unit (OU) logical architecture, Group Policy Object (GPO) security hardening, Kerberos/NTLM authentication layers, time synchronization (NTP), and System State backup procedures.
A highly available topology is designed by determining the namespace, Forest/Domain hierarchy, Active Directory Sites & Services, and integrated DNS infrastructure requirements.
A hierarchical Organizational Unit (OU) structure, security groups, user account standards, and a Tiered Administration model compliant with Privileged Account Management (PAM) principles are created.
A GPO structure is implemented to centralize device and user management, including LAPS, password policies, security baselines, and restriction rules.
A secondary Domain Controller (Replica DC) is set up for high availability; System State and authoritative/non-authoritative backups are tested for recovery scenarios.

A single DC may be sufficient in test or isolated environments with a small scale; however, for production environments, it is recommended to install at least two Domain Controllers to eliminate the single point of failure (SPOF) risk.
Yes, the Entra Connect (Azure AD Connect) tools can be used to integrate the local Active Directory infrastructure with Microsoft Entra ID; hybrid identity architecture and Password Hash Synchronization (PHS) or Pass-Through Authentication (PTA) can be configured.
Technically, domain renaming is possible, but due to DNS dependencies, certificate authorities, and application integration risks, it is generally not recommended. Instead, a controlled Active Directory migration to a new domain structure is a safer method.
