Use this document to resolve one bounded operational decision: Assign the Windows DNSSEC Key Master only to a qualifying authoritative server. Only the official source and traced locations below supply facts. Confirm applicability before acting.

\n

Source fact:

\n

The official DNSSEC Key Master from Microsoft supports the following bounded statements:

\n\n

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.

\n

What the source does not establish

\n

The role description does not provide a complete key ceremony, backup, cryptoperiod, hardware-protection, or incident-recovery design. 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.

\n

Applicability questions

\n\n

DSE recommendation:

\n

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.

\n

For an approved change, define prerequisites, a limited test path, success and stop conditions, monitoring, and rollback. Check Active Directory replication, domain-controller health, service accounts, routing, time, certificates, and upstream resolution in design order. Protect credentials, keys, recovery material, personal data, and sensitive topology in evidence.

\n

Verification and evidence

\n

Evidence should let another reviewer reproduce this decision. Retain observations beside the traced locations Section ‘What is a DNSSEC Key Master?’; Sections ‘What is a DNSSEC Key Master?’ and ‘Requirements’. Favor PowerShell exports, zone and policy inventories, sanitized query tests, event-channel data, replication state, and rollback commands, linked to stable identifiers, time, and operator.

\n

Keep before-state evidence, approval, test or change result, exceptions, and after-state evidence together. Use an approved lab, window, or nonproduction path for risky tests. Set a recheck trigger for version, architecture, dependency, vendor, incident, or ownership change. A check proves only what was observed.
