NS_I_STOP_CUB — 0x400D005C
Treat this code as a record of administrator-requested Content Server stop: in the operation that returned it, an administrator initiated shutdown of the named Content Server instance.
What the status actually records
Administrative information messages record who requested a transition and which object was targeted. In the context of administrator-requested Content Server stop, they do not guarantee that the requested start, stop, rebuild, or removal completed, so the follow-up object-state event is essential. Locate the first component changing state in this condition and distinguish later summary errors.
Important boundary. The event is an administrative transition; a later crash or incomplete drain should be diagnosed separately. Record the exact constant and returning API.
Evidence before intervention
| Incident fact | What it separates |
|---|---|
| Administrator location, server identity, request timestamp, and reason | Shows whether the status is expected information, a warning, or the first failure in the event sequence. |
| Active sessions, peer links, disk operations, and pending logging data | Ties the message to one server object and one transition instead of a later retry. |
| Graceful-shutdown versus forced-termination events | Separates configuration or identity from storage, parser, network, or lifecycle state. |
| Cluster routing behavior before and after the request | Provides a stable before/after comparison for the proposed correction. |
Preserve the smallest reproducible evidence set and redact client content, credentials, and private network details before sharing it.
A controlled diagnostic path
- Stop an idle test server and preserve the complete shutdown sequence. Keep media bytes, server identity, and unrelated publishing-point settings fixed.
- Compare graceful stop with service termination only in a disposable environment. Use a disposable publishing point or maintenance window when the test can alter server or storage state.
- Verify that peer routing moves new requests before the process exits. Retain a known-good stream, session, or server object so a broad restart is not mistaken for repair of the reported failure.
Stop after the first comparison that moves the boundary and diagnose the replacement status independently instead of accumulating unrelated server changes.
How to distinguish nearby outcomes
- Known-good comparison succeeds: isolate the production object or configuration associated with the failing operation.
- Same failure on the control: investigate the shared server, plug-in, storage, topology, or network layer before changing media content.
- Different status after one change: preserve both results; the first rejected condition was removed, but the operation is not yet proved complete.
Correction and acceptance criteria
Correction: Repair orchestration that stops the wrong instance or bypasses drain, and ensure pending disk and logging operations are closed cleanly. Keep the original server configuration, event sequence, object inventory, input hash, and topology snapshot so the change can be reversed and explained.
Accept the repair only when the requested instance drains, closes links and disks in order, exits without crash events, and can start cleanly again. Repeat the original supported operation under the original identity and object state; a simplified media file, replacement server, new session, or different client is useful comparison evidence but not final regression proof.

Use these Microsoft references for the formal contract and combine them with the exact server or catalog evidence from the incident: Check version-specific behavior against the Windows Media Services and SDK generation that produced the event.
- Microsoft Open Specifications: HRESULT values — defines the formal status or component boundary.
- Microsoft: Windows Media Services 9 Series SDK — documents the relevant API or lifecycle.
- Microsoft: Windows Media Services SDK architecture — provides the architecture, format, or protocol context.
- Microsoft: programming the Windows Media server object model — supports the controlled verification criteria.
