NS_E_BUSY
NS_E_BUSY — 0xC00D0025
Diagnosing NS_E_BUSY
NS_E_BUSY identifies this Windows Media Services boundary: the requested resource is in use.
Why this boundary matters
This HRESULT is tied to a particular server object and state transition. Preserve the object identity/generation, current and requested states, and the operation or outstanding owner that prevents the transition before restarting the service.
Evidence to collect
| Field | What to preserve |
|---|---|
| Object | Server object/title/session identity and its current generation. |
| State | Current state, requested state and the operation that attempted the transition. |
| Owner | Outstanding reference, session or administrative action that still owns or blocks the object. |
| First result | Earliest component result from the failed state transition before cleanup/retry. |
Decision rule
A restart can erase ownership evidence. Prefer proving which object/reference blocks the transition and then repeat on the same logical object or a deliberately fresh generation.
Focused test
Identify the server object or session that owns the resource and the operation holding it. Release or complete only that operation, then retry against the same object generation.
Verification
Repeat the same logical state transition after correcting the identified owner or state. Confirm the object changes state in the expected order; a restart that merely creates a fresh object is only a comparison unless it explains the original ownership failure.

For automation, log the symbolic name as well as the numeric HRESULT. The symbolic name preserves the Windows Media subsystem boundary that a generic COM error formatter can obscure.
