Only the official source and traced locations below supply facts. Confirm applicability before acting. ## Source fact: The official [Get-DnsServerTrustAnchor](https://learn.microsoft.com/en-us/powershell/module/dnsserver/get-dnsservertrustanchor?view=windowsserver2025-ps) from Microsoft supports the following bounded statements: - At DESCRIPTION, Microsoft states: “The Get-DnsServerTrustAnchor cmdlet gets trust anchors on a Domain Name System (DNS) server.” The research record locates this support at DESCRIPTION. - At DESCRIPTION, Microsoft states: “If you do not specify the name of a trust anchor to get, the cmdlet returns all trust anchors.” The research record locates this support at DESCRIPTION. Only the traced statements above are asserted as source facts. Apply the review to Windows DNS servers, AD-integrated zones, policies, forwarders, logging channels, clients, and administrative 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 Active Directory replication, domain-controller health, service accounts, routing, time, certificates, and upstream resolution, and treat examples or options as conditional inputs rather than defaults. ## Applicability questions - For source statement 1 at DESCRIPTION, which observable configuration, record, or test can confirm applicability here? - For source statement 2 at DESCRIPTION, which observable configuration, record, or test can confirm applicability here? - Which deployed instance of Windows DNS servers, AD-integrated zones, policies, forwarders, logging channels, clients, and administrative roles will be compared with the source, and why that instance? - How will the review distinguish a source mismatch from a failure in Active Directory replication, domain-controller health, service accounts, routing, time, certificates, and upstream resolution? - Who approves the conclusion, exception, test window, and rollback threshold? ## 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 Windows DNS servers, AD-integrated zones, policies, forwarders, logging channels, clients, and administrative roles, observed and expected states, owner, and reason for deviation. Do not move from citation to production in one step. Pilot the decision where practical, observe agreed signals, retain a reversal point, and verify Active Directory replication, domain-controller health, service accounts, routing, time, certificates, and upstream resolution. Handle credentials, keys, recovery data, and personal information through approved secure channels. ## Verification and evidence A reviewer should be able to retrace the decision from DESCRIPTION; DESCRIPTION through PowerShell exports, zone and policy inventories, sanitized query tests, event-channel data, replication state, and rollback commands. Record what was collected, where, when, by whom, and which system or role it represents. Label this evidence set DSE-20260827-285 so observations, approvals, exceptions, and later rechecks cannot be substituted from another source review. Close the review only when the evidence, exception handling, resulting action, and after-state are linked. Schedule a new review after material technical, organizational, incident, or source changes; today’s observation is not a continuing guarantee. ## Official references - [Get-DnsServerTrustAnchor](https://learn.microsoft.com/en-us/powershell/module/dnsserver/get-dnsservertrustanchor?view=windowsserver2025-ps) — Microsoft ## Primary reference - Name: Get-DnsServerTrustAnchor - Authority: Microsoft Learn - URL: https://learn.microsoft.com/en-us/powershell/module/dnsserver/get-dnsservertrustanchor?view=windowsserver2025-ps - Source publication date: Not stated by the source ## Citation and use Preferred citation: “Get-DnsServerTrustAnchor: inventory dns server trust anchor with bounded evidence,” DSE Security, https://update.dsesecurity.com/updates/get-dnsservertrustanchor-inventory-dns-server-trust-anchor-with-bounded-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.
