Deploying Windows Server Active Directory Domain Services (AD DS) enables centralized identity, security policy enforcement, and infrastructure management across domain-joined endpoints.
1. Domain Infrastructure & DNS Server
- Active Directory Domain Services (AD DS): Configured central domain controller for user authentication, Organizational Units (OU), and device domain joining.
- Windows Server DNS: Integrated Active Directory DNS zone for internal domain name resolution, forward/reverse lookup zones, and WAN forwarders.
2. Group Policy Object (GPO) Implementations
A. Password Policy Enforcements
Configured Default Domain Policy GPO to enforce credential security standards across all domain users:
- Password Length: Enforced minimum password length of 8 characters.
- Password Expiration: Enforced password change every 3 months (90 days).
- Account Lockout Policy: Configured lockout after repeated failed logon attempts to prevent brute-force attacks.
B. Corporate Desktop Wallpaper Standardization
- Configured User Configuration GPO under Desktop Wallpaper settings.
- Standardized mandatory corporate background wallpaper across all employee workstations via centralized network share access (
\\Domain\SYSVOL\Wallpapers\corporate.png).
C. Local Administrator Account Management
- Restricted local administrative privileges on workstation endpoints using GPO Restricted Groups and LAPS (Local Administrator Password Solution).
- Enforced domain user accounts to run with standard non-administrator privileges to prevent unauthorized software installations.
- Configured dedicated local admin credentials managed centrally for IT support maintenance tasks.
3. Summary
Combining AD DS authentication, DNS resolution, and tailored GPO policies (Password Expiration, Wallpaper Branding, and Local Admin Restriction) ensures consistent security compliance and streamlined IT support operations.
