Active Directory Scripts

Recommendation: Use this AD automation suite to deploy, secure, and operate Active Directory reliably at enterprise scale.

Why it matters

  • Reduce risk: codified hardening, repeatable deployments, and validated recovery.
  • Move faster: opinionated scripts and templates for day-1 to day-N operations.
  • Prove compliance: built-in auditing, RBAC alignment, and baseline enforcement.

How it works (high-level)

  • Modular PowerShell functions grouped by deployment, configuration, security, monitoring, troubleshooting.
  • Example-driven workflows and test harnesses to validate environments safely.
  • JSON configuration templates for consistent, repeatable changes.

Overview

This solution provides comprehensive PowerShell scripts for Windows Active Directory management, covering all aspects of AD deployment, configuration, security, monitoring, and troubleshooting.
