Project Overview

Centralized identity and domain administration

This project involved designing and administering a Microsoft Active Directory environment that recreated core services commonly used within business and enterprise networks.

The infrastructure provided centralized user authentication, computer management, DNS name resolution, organizational structure, security-group administration, and policy enforcement.

Multiple Windows Server systems and Windows client machines were used to validate domain functionality, redundancy, communication, and administrative workflows.

Architecture

Domain-services architecture

Business Value

Secure and manageable enterprise identity

Centralized domain services allow organizations to manage user identities, computers, authentication, security policies, and access consistently. This reduces administrative overhead, improves security, supports organizational growth, and creates a reliable foundation for enterprise applications and infrastructure.
