Only the official source and traced locations below supply facts. Confirm applicability before acting. ## Source fact: The official [Appendix M – Document Links and Recommended Reading](https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/manage/Appendix-M--Document-Links-and-Recommended-Reading) from Microsoft supports the following bounded statements: - At Document Links, Microsoft states: “The following table contains a list of links to external documents and their URLs so that readers of hard copies of this document can access this information.” The research record locates this support at Document Links. - At Document Links, Microsoft states: “The links are listed in the order they appear in the document.” The research record locates this support at Document Links. Do not import neighboring assumptions into the source record. The supported task is a scoped comparison involving forests, domains, controllers, directory partitions, trusts, sites, replication links, service accounts, and delegated roles and the conditions the source actually describes. ## 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 Document Links, which observable configuration, record, or test can confirm applicability here? - For source statement 2 at Document Links, 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. Use a two-person review for the source interpretation and the resulting operational decision. 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 Tie each conclusion back to Document Links; Document Links and to observable material such as directory and policy exports, replication and locator tests, event logs, trust state, role ownership, and controlled authentication tests. Preserve provenance and stable identifiers without copying secrets into the evidence set. Label this evidence set DSE-20260827-075 so observations, approvals, exceptions, and later rechecks cannot be substituted from another source review. Keep before-state evidence, approval, test or change result, exceptions, and after-state evidence together. Use an approved lab, window, or nonproduction path for risky tests. Set a recheck trigger for version, architecture, dependency, vendor, incident, or ownership change. A check proves only what was observed. ## Official references - [Appendix M – Document Links and Recommended Reading](https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/manage/Appendix-M--Document-Links-and-Recommended-Reading) — Microsoft ## Primary reference - Name: Appendix M - Document Links and Recommended Reading - Authority: Microsoft Learn - URL: https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/manage/Appendix-M--Document-Links-and-Recommended-Reading - Source publication date: Not stated by the source ## Citation and use Preferred citation: “Review Appendix M - Document Links and Recommended Reading before AD/DNS changes,” DSE Security, https://update.dsesecurity.com/updates/review-appendix-m-document-links-and-recommended-reading-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.
