Only the official source and traced locations below supply facts. Confirm applicability before acting. ## Source fact: The official [Access is denied when you promote domain controller](https://learn.microsoft.com/en-us/troubleshoot/windows-server/active-directory/access-denied-create-ntds-settings-object) from Microsoft supports the following bounded statements: - At Introduction below H1, Microsoft states: “This article provides a solution to fix an error (Access is denied) that occurs when you promote Windows Server 2012 R2 or later domain controllers in an existing domain.” The research record locates this support at Introduction below H1. - At Symptoms, Microsoft states: “When you try to promote Windows Server 2012 R2 or later domain controllers in an existing domain, the operation fails with an “Access is denied” error.” The research record locates this support at Symptoms. Do not import neighboring assumptions into the source record. The supported task is a scoped comparison involving Active Directory objects, search bases, domain controllers, delegated roles, cmdlet parameters, and the DNS paths used to locate directory services 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. Do not read the source as proof of implementation or permission to change production. Its guidance remains conditional on Active Directory replication, Windows DNS, domain-controller location, time, network reachability, privileges, and protected credentials and the environment’s recorded constraints. ## 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 Symptoms, 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. Use a two-person review for the source interpretation and the resulting operational decision. 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. For an approved change, define prerequisites, a limited test path, success and stop conditions, monitoring, and rollback. Check Active Directory replication, Windows DNS, domain-controller location, time, network reachability, privileges, and protected credentials in design order. Protect credentials, keys, recovery material, personal data, and sensitive topology in evidence. ## Verification and evidence Keep the source locations Introduction below H1; Symptoms adjacent to the sanitized artifacts used for comparison. Prefer sanitized command transcripts, parameter records, directory exports, authorization records, DNS locator tests, and before-and-after state, with enough identity and timing data for an independent recheck. Label this evidence set DSE-20260827-472 so observations, approvals, exceptions, and later rechecks cannot be substituted from another source review. Retain the starting state, authorization, execution record, outcome, deviation, and final state as one review package. Move disruptive checks to an approved test path. Reopen the decision when versions, design, dependencies, ownership, or official guidance changes. ## Official references - [Access is denied when you promote domain controller](https://learn.microsoft.com/en-us/troubleshoot/windows-server/active-directory/access-denied-create-ntds-settings-object) — Microsoft ## Primary reference - Name: Access is denied when you promote domain controller - Authority: Microsoft Learn - URL: https://learn.microsoft.com/en-us/troubleshoot/windows-server/active-directory/access-denied-create-ntds-settings-object - Source publication date: Not stated by the source ## Citation and use Preferred citation: “Validate Access is denied when you promote domain controller with AD/DNS evidence,” DSE Security, https://update.dsesecurity.com/updates/validate-access-is-denied-when-you-promote-domain-controller-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.
