Keep this document to one review outcome: Migrate eligible services to device-bound dMSA identities. Only the official source and traced locations below supply facts. Confirm applicability before acting.

\n

Source fact:

\n

The official Delegated Managed Service Accounts overview in Windows Server 2025 from Microsoft supports the following bounded statements:

\n\n

These statements are the factual basis for this document. Do not extend them into a broader assurance. Review forests, domains, controllers, directory partitions, trusts, sites, replication links, service accounts, and delegated roles only where the source and recorded environment align.

\n

What the source does not establish

\n

dMSA requires Windows Server 2025 support and application compatibility; migration must be reversible. Do not read the source as proof of implementation or permission to change production. Its guidance remains conditional on Windows DNS, time synchronization, network reachability, PKI, backups, virtualization safeguards, and privileged identity and the environment’s recorded constraints.

\n

Applicability questions

\n\n

DSE recommendation:

\n

DSE recommends using the cited source as the evidence anchor for this decision. Start with applicability, then compare the observed state with the cited source. Record the source location, examined part of forests, domains, controllers, directory partitions, trusts, sites, replication links, service accounts, and delegated roles, observed and expected states, owner, and reason for deviation.

\n

Translate the conclusion into change control only after documenting dependencies, impact, test method, expected signals, failure signals, and restoration steps. Include Windows DNS, time synchronization, network reachability, PKI, backups, virtualization safeguards, and privileged identity, while excluding secrets and sensitive personal or topology data from ordinary tickets.

\n

Verification and evidence

\n

Build a reproducible chain from Opening overview; Opening overview to the observed environment. Useful domain evidence includes directory and policy exports, replication and locator tests, event logs, trust state, role ownership, and controlled authentication tests; label every item with scope, timestamp, collector, and stable identifier.

\n

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.
