Understanding the number and names of domains in your forest is critical for:

  • Security Boundaries: Each domain represents a security boundary with its own policies
  • Trust Management: Understanding trust relationships between domains
  • Administrative Scope: Knowing where administrative permissions apply
  • Compliance Scope: Determining the scope of compliance assessments
  • Disaster Recovery: Planning recovery procedures across all domains

Operational

  • Minimize Domains: Fewer domains reduce complexity and attack surface
  • Document Structure: Maintain documentation of all domains and their purposes
  • Review Regularly: Periodically review if all domains are still needed
  • Consistent Policies: Apply consistent security policies across all domains

This test retrieves all domains from the Active Directory forest and counts them. It also lists all domain names for reference.
