Windows Server & Active Directory Infrastructure
Scope: Active Directory Domain Services (AD DS), Group Policy Objects (GPO), DNS Forwarding, & Failover DHCP
Deployment Overview
Deployed and configured a centralized Windows Server Active Directory Domain Services (AD DS) environment designed for multi-departmental user authentication and endpoint management. The project establishes hierarchical Organizational Unit (OU) structures, enforces domain-wide security baselines through targeted Group Policy Objects (GPO), and ensures reliable network resolution using integrated Active Directory-Integrated DNS and high-availability DHCP failover.
Domain Controller & AD DS Topology
Active Directory Domain Services & GPO Hardening Architecture
Core Active Directory & Server Pillars
AD DS & OU Structure Design
Structured logical Organizational Units (OUs) by department and site location. Implemented role-based security groups (RBAC) to enforce least-privilege administrative rights and streamlined user account provisioning.
GPO Security Baselines
Deployed domain security policies enforcing complex password requirements, account lockout thresholds, automated screen saver locks, software restriction policies, and centralized firewall rules across client endpoints.
AD-Integrated DNS & Resolution
Configured secure, Active Directory-Integrated DNS zones with conditional forwarders and root hints. Ensured fast domain locator record lookup (SRV) and dynamic reverse lookup updates for managed devices.
DHCP Scopes & Failover Pairs
Configured load-balanced DHCP scopes with reservation parameters for static network resources. Established hot-standby DHCP failover pairs to maintain zero IP-address leasing downtime during DC maintenance.
