A virtualised Active Directory environment simulating real enterprise infrastructure. AD DS & DNS role installation, OU hierarchy design, RBAC security groups, and AD Sites & Services.
Technologies
Project Overview
Identity & Access Management: Promoted DC01 (Windows Server 2022) to domain controller for a new forest — helpdesk.lab. Integrated DNS, configured DSRM, verified domain health with Get-ADDomain.
Configuration Management: Designed a department-based OU hierarchy (_STAFF/IT, HR, Finance, Sales; _COMPUTERS; _GROUPS; _DISABLED) mirroring real enterprise CI structure.
Access Control & RBAC: Created department security groups (GRP_IT, GRP_HR, GRP_Finance, GRP_Sales, GRP_AllStaff) under _GROUPS OU for least-privilege access.
Multi-site Topology: Configured London-HQ (192.168.100.0/24) and Manchester-Branch (192.168.1.0/24) AD sites — simulating distributed enterprise environments.
