Only the official source and traced locations below supply facts. Confirm applicability before acting. ## Source fact: The official [Configure an authoritative time](https://learn.microsoft.com/en-us/troubleshoot/windows-server/active-directory/configure-authoritative-time-server) from Microsoft supports the following bounded statements: - At Introduction below H1, Microsoft states: “This article describes how to configure the Windows Time service and troubleshoot when the Windows Time service doesn’t work correctly.” The research record locates this support at Introduction below H1. - At Introduction below H1, Microsoft states: “_Applies to:_ Windows Server (All supported versions) _Original KB number:_ 816042.” The research record locates this support at Introduction below H1. The source support ends with the statements listed above. Use them to examine Active Directory objects, search bases, domain controllers, delegated roles, cmdlet parameters, and the DNS paths used to locate directory services 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. It does not establish a deployment’s current state, authorize a production change, prove compliance, or show that Active Directory replication, Windows DNS, domain-controller location, time, network reachability, privileges, and protected credentials are healthy. Documented options are review inputs, not universal mandates. ## 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? - Which owner can attest to the recorded state of Active Directory objects, search bases, domain controllers, delegated roles, cmdlet parameters, and the DNS paths used to locate directory services, including exceptions? - What baseline for Active Directory replication, Windows DNS, domain-controller location, time, network reachability, privileges, and protected credentials must accompany the source-specific observation? - Which success, stop, and escalation criteria are written before testing begins? ## 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 Active Directory objects, search bases, domain controllers, delegated roles, cmdlet parameters, and the DNS paths used to locate directory services, 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 Active Directory replication, Windows DNS, domain-controller location, time, network reachability, privileges, and protected credentials, while excluding secrets and sensitive personal or topology data from ordinary tickets. ## Verification and evidence Build a reproducible chain from Introduction below H1; Introduction below H1 to the observed environment. Useful domain evidence includes sanitized command transcripts, parameter records, directory exports, authorization records, DNS locator tests, and before-and-after state; label every item with scope, timestamp, collector, and stable identifier. Label this evidence set DSE-20260827-392 so observations, approvals, exceptions, and later rechecks cannot be substituted from another source review. Preserve both successful and failed observations, along with approval and rollback evidence. Avoid uncontrolled production experiments. Assign an expiry or event-driven recheck so the conclusion is not treated as permanent. ## Official references - [Configure an authoritative time](https://learn.microsoft.com/en-us/troubleshoot/windows-server/active-directory/configure-authoritative-time-server) — Microsoft ## Primary reference - Name: Configure an authoritative time - Authority: Microsoft Learn - URL: https://learn.microsoft.com/en-us/troubleshoot/windows-server/active-directory/configure-authoritative-time-server - Source publication date: Not stated by the source ## Citation and use Preferred citation: “Validate Configure an authoritative time with AD/DNS evidence,” DSE Security, https://update.dsesecurity.com/updates/validate-configure-an-authoritative-time-with-ad-dns-evidence/ 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.
