Only the official source and traced locations below supply facts. Confirm applicability before acting. ## Source fact: The official [Add-DnsServerVirtualizationInstance](https://learn.microsoft.com/en-us/powershell/module/dnsserver/add-dnsservervirtualizationinstance?view=windowsserver2025-ps) from Microsoft supports the following bounded statements: - At DESCRIPTION, Microsoft states: “The Add-DnsServerVirtualizationInstance cmdlet adds a virtualization instance to a DNS Server.” The research record locates this support at DESCRIPTION. - At DESCRIPTION, Microsoft states: “A Virtualizaton instance is a logical partition in a DNS Server that is capable of hosting zones and zone scopes independently.” The research record locates this support at DESCRIPTION. Do not import neighboring assumptions into the source record. The supported task is a scoped comparison involving Windows DNS servers, AD-integrated zones, policies, forwarders, logging channels, clients, and administrative roles 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. It does not establish a deployment’s current state, authorize a production change, prove compliance, or show that Active Directory replication, domain-controller health, service accounts, routing, time, certificates, and upstream resolution are healthy. Documented options are review inputs, not universal mandates. ## 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. Use a two-person review for the source interpretation and the resulting operational decision. 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. Translate the conclusion into change control only after documenting dependencies, impact, test method, expected signals, failure signals, and restoration steps. Include Active Directory replication, domain-controller health, service accounts, routing, time, certificates, and upstream resolution, while excluding secrets and sensitive personal or topology data from ordinary tickets. ## Verification and evidence Build a reproducible chain from DESCRIPTION; DESCRIPTION to the observed environment. Useful domain evidence includes PowerShell exports, zone and policy inventories, sanitized query tests, event-channel data, replication state, and rollback commands; label every item with scope, timestamp, collector, and stable identifier. Label this evidence set DSE-20260827-272 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 - [Add-DnsServerVirtualizationInstance](https://learn.microsoft.com/en-us/powershell/module/dnsserver/add-dnsservervirtualizationinstance?view=windowsserver2025-ps) — Microsoft ## Primary reference - Name: Add-DnsServerVirtualizationInstance - Authority: Microsoft Learn - URL: https://learn.microsoft.com/en-us/powershell/module/dnsserver/add-dnsservervirtualizationinstance?view=windowsserver2025-ps - Source publication date: Not stated by the source ## Citation and use Preferred citation: “Add-DnsServerVirtualizationInstance: stage additions to dns server virtualization instance with rollback checks,” DSE Security, https://update.dsesecurity.com/updates/add-dnsservervirtualizationinstance-stage-additions-to-dns-server-virtualization-instance-with/ 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.
