# Review Understanding the Active Directory Logical Model before AD/DNS changes > Use Understanding the Active Directory Logical Model to review this narrow operational decision without extending the source beyond its stated scope. - Canonical URL: https://update.dsesecurity.com/updates/review-understanding-the-active-directory-logical-model-before-ad-dns-changes/ - Publisher: Detection Systems & Engineering (DSE Security) - Author: DSE Security Editorial Team - Published: 2026-08-27T17:06:16+00:00 - Modified: 2026-08-27T17:11:09+00:00 - Last reviewed by DSE: 2026-08-27 - Resource type: Playbook - DSE priority: Advisory - Topics: Cybersecurity, Microsoft 365 & Identity, Networks & Infrastructure - Reading time: 3 minutes ## What you need to know Use Understanding the Active Directory Logical Model to review this narrow operational decision without extending the source beyond its stated scope. ## Potentially affected Teams, systems, services, or facilities within the stated scope of Understanding the Active Directory Logical Model ## DSE recommendation Compare the observed state with the cited official source, document applicability and exceptions, and test any approved change with rollback safeguards. ## Article Keep this document to one review outcome: Review Understanding the Active Directory Logical Model before AD/DNS changes. Only the official source and traced locations below supply facts. Confirm applicability before acting. ## Source fact: The official [Understanding the Active Directory Logical Model](https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/plan/Understanding-the-Active-Directory-Logical-Model) from Microsoft supports the following bounded statements: - At Introduction below H1, Microsoft states: “Designing your logical structure for Active Directory Domain Services (AD DS) involves defining the relationships between the containers in your directory.” The research record locates this support at Introduction below H1. - At Introduction below H1, Microsoft states: “These relationships might be based on administrative requirements, such as delegation of authority, or they might be defined by operational requirements, such as the need to control replication.” The research record locates this support at Introduction below H1. The source support ends with the statements listed above. Use them to examine forests, domains, controllers, directory partitions, trusts, sites, replication links, service accounts, and delegated roles in the applicable environment, not to imply a wider guarantee. ## What the source does not establish The cited page and retained statements do not establish the current state of any DSE or customer environment, prove that the documented configuration is applicable, or authorize a production change. Confirm supported versions, dependencies, and the current live source before use. The citation is not a substitute for observed state, authorization, compliance evidence, or dependency health. Examine Windows DNS, time synchronization, network reachability, PKI, backups, virtualization safeguards, and privileged identity before translating the source into an operational decision. ## Applicability questions - For source statement 1 at Introduction below H1, which observable configuration, record, or test can confirm applicability here? - For source statement 2 at Introduction below H1, which observable configuration, record, or test can confirm applicability here? - Within forests, domains, controllers, directory partitions, trusts, sites, replication links, service accounts, and delegated roles, which versions, roles, and configuration states define the review population? - Could Windows DNS, time synchronization, network reachability, PKI, backups, virtualization safeguards, and privileged identity invalidate the test, hide a failure, or change applicability? - Who owns the decision, and which observation requires stopping, escalation, or rollback? ## DSE recommendation: DSE recommends using the cited source as the evidence anchor for this decision. Make the source, asset scope, owner, and expected outcome explicit in the review record. Record the source location, examined part of forests, domains, controllers, directory partitions, trusts, sites, replication links, service accounts, and delegated roles, observed and expected states, owner, and reason for deviation. For an approved change, define prerequisites, a limited test path, success and stop conditions, monitoring, and rollback. Check Windows DNS, time synchronization, network reachability, PKI, backups, virtualization safeguards, and privileged identity in design order. Protect credentials, keys, recovery material, personal data, and sensitive topology in evidence. ## Verification and evidence A reviewer should be able to retrace the decision from Introduction below H1; Introduction below H1 through directory and policy exports, replication and locator tests, event logs, trust state, role ownership, and controlled authentication tests. Record what was collected, where, when, by whom, and which system or role it represents. Label this evidence set DSE-20260827-070 so observations, approvals, exceptions, and later rechecks cannot be substituted from another source review. Record the decision even when no change is made, including uncertainty and the next trigger. Use safe testing conditions for disruptive work, preserve rollback proof, and revisit the conclusion after relevant platform, dependency, vendor, or ownership changes. ## Official references - [Understanding the Active Directory Logical Model](https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/plan/Understanding-the-Active-Directory-Logical-Model) — Microsoft ## Primary reference - Name: Understanding the Active Directory Logical Model - Authority: Microsoft Learn - URL: https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/plan/Understanding-the-Active-Directory-Logical-Model - Source publication date: Not stated by the source ## Citation and use Preferred citation: “Review Understanding the Active Directory Logical Model before AD/DNS changes,” DSE Security, https://update.dsesecurity.com/updates/review-understanding-the-active-directory-logical-model-before-ad-dns-changes/ Publishing principles: https://update.dsesecurity.com/updates/dse-updates-editorial-methodology/ Usage and citation policy: https://update.dsesecurity.com/usage/ Copyright © 2026 Detection Systems & Engineering.
