Only the official source and traced locations below supply facts. Confirm applicability before acting. ## Source fact: The official [Remove-ADReplicationSubnet](https://learn.microsoft.com/en-us/powershell/module/activedirectory/remove-adreplicationsubnet?view=windowsserver2025-ps) from Microsoft supports the following bounded statements: - At SYNOPSIS, Microsoft states: “Deletes the specified Active Directory replication subnet object from the directory.” The research record locates this support at SYNOPSIS. - At DESCRIPTION, Microsoft states: “The Remove-ADReplicationSubnet cmdlet deletes the specified Active Directory replication subnet object from the directory.” The research record locates this support at DESCRIPTION. Keep the evidence boundary at these traced claims. They support a review of Active Directory objects, search bases, domain controllers, delegated roles, cmdlet parameters, and the DNS paths used to locate directory services; they do not support conclusions outside the source’s stated conditions. ## 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, Windows DNS, domain-controller location, time, network reachability, privileges, and protected credentials, and treat examples or options as conditional inputs rather than defaults. ## Applicability questions - For source statement 1 at SYNOPSIS, 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? - What inventory proves which parts of Active Directory objects, search bases, domain controllers, delegated roles, cmdlet parameters, and the DNS paths used to locate directory services are in and out of scope? - Which condition in Active Directory replication, Windows DNS, domain-controller location, time, network reachability, privileges, and protected credentials must be healthy before evidence is trustworthy? - What result would disprove the working assumption and return the issue to the owner? ## DSE recommendation: DSE recommends using the cited source as the evidence anchor for this decision. Anchor the review in the cited section and keep observation separate from interpretation. 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. 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, Windows DNS, domain-controller location, time, network reachability, privileges, and protected credentials. 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 SYNOPSIS; DESCRIPTION through sanitized command transcripts, parameter records, directory exports, authorization records, DNS locator tests, and before-and-after state. Record what was collected, where, when, by whom, and which system or role it represents. Label this evidence set DSE-20260827-165 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 - [Remove-ADReplicationSubnet](https://learn.microsoft.com/en-us/powershell/module/activedirectory/remove-adreplicationsubnet?view=windowsserver2025-ps) — Microsoft ## Primary reference - Name: Remove-ADReplicationSubnet - Authority: Microsoft Learn - URL: https://learn.microsoft.com/en-us/powershell/module/activedirectory/remove-adreplicationsubnet?view=windowsserver2025-ps - Source publication date: Not stated by the source ## Citation and use Preferred citation: “Remove-ADReplicationSubnet: remove adreplication subnet with bounded evidence,” DSE Security, https://update.dsesecurity.com/updates/remove-adreplicationsubnet-remove-adreplication-subnet-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.
