NS_I_LOGGING_FAILED
NS_I_LOGGING_FAILED — 0x400D006E
This result belongs to Windows Media logging failure not to a generic restart checklist, because a server or publishing-point logging operation could not persist its record even though streaming may continue.
Place in the component lifecycle
Logging and event plug-ins are separate from the streaming data path. In the context of Windows Media logging failure, their failure can leave media delivery apparently healthy while removing the chronology needed for capacity, audit, and incident analysis. Locate the first component that changes state and distinguish later summary errors.
Important distinction. A logging failure is an observability and audit problem, not direct proof that the media stream itself failed.
Build a reliable incident timeline
- Logging plug-in name and state, target path or sink, service identity, and event timestamp
- Disk space, ACLs, file locks, rotation state, and plug-in error details
- Server/publishing-point event that should have generated the record
- Gap boundaries in the log and any buffered records lost on restart
Tests that change one variable
- Write one controlled event through the configured logging plug-in. Retain a known-good stream, session, or server object so a broad restart is not mistaken for repair of the reported failure.
- Redirect logging to a temporary known-good local target while keeping server traffic unchanged.
- Rotate or reopen the target under trace to identify the first failed file operation. Keep media bytes, server identity, and unrelated publishing-point settings fixed.
Stop after the first comparison that changes the result and diagnose the replacement status independently instead of accumulating unrelated server changes.
How to interpret the comparison
| Observed comparison | Interpretation |
|---|---|
| A known-good object succeeds through the same component | The platform path exists; concentrate on the production object, identity, metadata, or state captured above. |
| The control fails at the same first operation | Preserve server, storage, plug-in, topology, and network evidence before modifying media or publishing-point data. |
| The status changes after one deliberate adjustment | The failure point changed; the replacement status now describes the next contract to investigate. |
Repair and regression proof
Correction: Repair the logging plug-in, destination, rotation, or service permissions and account for the period with incomplete records.
Accept the repair only when controlled events are persisted in order, rotation succeeds, and no silent gaps appear across service restart.
Technical references
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.
- Microsoft: Windows Media Services 9 Series SDK — documents the relevant API or lifecycle.
- Microsoft: custom logging plug-ins — provides the architecture, format, or protocol context.
- Microsoft: Windows Media Services server object model — supports the controlled verification criteria.
