Only the official source and traced locations below supply facts. Confirm applicability before acting. ## Source fact: The official [Active Directory Forest Recovery – Perform initial recovery](https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/manage/forest-recovery-guide/ad-forest-recovery-perform-initial-recovery) from Microsoft supports the following bounded statements: - At Introduction below H1, Microsoft states: “Restore the first writeable domain controller in each domain Reconnect each restored writeable domain controller to the network Add the global catalog to a domain controller in the forest root domain.” The research record locates this support at Introduction below H1. - At Restore the first writeable domain controller in each domain, Microsoft states: “Beginning with a writeable DC in the forest root domain, complete the steps in this section in order to restore the first DC.” The research record locates this support at Restore the first writeable domain controller in each domain. Only the traced statements above are asserted as source facts. Apply the review to forests, domains, controllers, directory partitions, trusts, sites, replication links, service accounts, and delegated roles after confirming that the source and deployed context match. ## 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. No current deployment state or change approval follows from the source alone. Validate Windows DNS, time synchronization, network reachability, PKI, backups, virtualization safeguards, and privileged identity, and treat examples or options as conditional inputs rather than defaults. ## 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 Restore the first writeable domain controller in each domain, 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. Begin by recording scope and current state before deciding whether a change is warranted. 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. Translate the conclusion into change control only after documenting dependencies, impact, test method, expected signals, failure signals, and restoration steps. Include Windows DNS, time synchronization, network reachability, PKI, backups, virtualization safeguards, and privileged identity, while excluding secrets and sensitive personal or topology data from ordinary tickets. ## Verification and evidence Build a reproducible chain from Introduction below H1; Restore the first writeable domain controller in each domain to the observed environment. Useful domain evidence includes directory and policy exports, replication and locator tests, event logs, trust state, role ownership, and controlled authentication tests; label every item with scope, timestamp, collector, and stable identifier. Label this evidence set DSE-20260827-034 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 - [Active Directory Forest Recovery – Perform initial recovery](https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/manage/forest-recovery-guide/ad-forest-recovery-perform-initial-recovery) — Microsoft ## Primary reference - Name: Active Directory Forest Recovery - Perform initial recovery - Authority: Microsoft Learn - URL: https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/manage/forest-recovery-guide/ad-forest-recovery-perform-initial-recovery - Source publication date: Not stated by the source ## Citation and use Preferred citation: “Trace Active Directory Forest Recovery - Perform initial recovery across Active Directory and Windows DNS,” DSE Security, https://update.dsesecurity.com/updates/trace-active-directory-forest-recovery-perform-initial-recovery-across-active-directory-and-windows/ 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.
