What does HRESULT 0xC00D2784 (NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT) mean?

NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT

The exact DRM condition

0xC00D2784 maps to NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT. Read it as a result from Windows Media DRM client API contract and object lifecycle: the DRM runtime cannot create the in-memory-store object required for this operation. Keeping the “unable to create inmemorystore object” boundary intact for NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT prevents a later playback message from hiding the original DRM failure, within the unable to create inmemorystore object workflow.

For NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT, the built-in message summarizes the user-visible outcome, while the symbolic phrase “unable to create inmemorystore object” preserves the exact WMDRM boundary for diagnosis. For this code, the proof step is to record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT, in the unable to create inmemorystore object path.

Place in the DRM workflow

The workflow around NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT matters: the DRM client exposes different objects for license management, individualization, encryption, backup, metering and device registration; failure to create one object does not prove that all DRM state is damaged, while tracing unable to create inmemorystore object. In addition, many operations are asynchronous and stateful, so object lifetime and completion ordering are part of the API contract, for the unable to create inmemorystore object boundary.

A useful investigation order

1. Preserve NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT, the calling interface and the first lower-level status before a wrapper replaces it, during unable to create inmemorystore object diagnosis.
2. Correlate NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT with one KID/license ID, content hash, device certificate or migration operation ID for the “unable to create inmemorystore object” path.
3. For NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT, reconstruct the state transition immediately preceding “unable to create inmemorystore object” instead of starting from the final player dialog.
4. Prove the boundary by ensuring you can record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT, in a unable to create inmemorystore object incident.
5. After you correct component/version or initialization state and create a fresh in-memory-store object, verify both the requested right and the final store/device state, for this unable to create inmemorystore object result.

State to capture before retry

Capture the first NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT occurrence before automatic retry, player teardown, store repair or license reacquisition changes the state, when reproducing unable to create inmemorystore object. The smallest useful record contains:

• Code-specific proof: record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT, within the unable to create inmemorystore object workflow.
• Protected identity: SDK/runtime version and linked DRM stub library, in the unable to create inmemorystore object path.
• Operation state: property name, type, size and initialization order, while tracing unable to create inmemorystore object.
• Persistence or transport: operation state, callback sequence and cancellation owner, for the unable to create inmemorystore object boundary.
• Security context: first inner HRESULT before an application replaces it with a generic error, during unable to create inmemorystore object diagnosis.
• Correlation point: exact interface method and object type being created, in a unable to create inmemorystore object incident.

For the “unable to create inmemorystore object” investigation, use KIDs, license IDs, hashes, certificate thumbprints, sizes and timestamps where possible. While diagnosing NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT, do not place content keys, complete license blobs, passwords, cookies or decrypted media in ordinary logs, for this unable to create inmemorystore object result.

Narrow remediation

Resolve NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT at its producing boundary: correct component/version or initialization state and create a fresh in-memory-store object, for the unable to create inmemorystore object boundary. For NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT, a player reinstall, reboot or new license request is useful only when it changes the “unable to create inmemorystore object” boundary and can be verified against the original evidence.

Representative case: The application reaches the in-memory-store stage but object construction fails before any content or server work begins, during unable to create inmemorystore object diagnosis.

Nearby results with different meanings

Several values can accompany the “unable to create inmemorystore object” condition in one incident. Order the NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT event chain by timestamp and prefer the first code produced at the lowest specific boundary over a later player-level summary, within the unable to create inmemorystore object workflow.

Verification after correction

Repeat the operation that originally returned NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT. For NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT, assert the exact HRESULT at the producing API in the failing “unable to create inmemorystore object” fixture; then change only the decisive precondition and confirm that the corrected run completes without substituting a neighboring DRM result. After correcting NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT, verify the requested action and the final license-store, secure-clock, device or migration state relevant to “unable to create inmemorystore object”.

What the missing object would have owned

In the NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT path, the in-memory store object normally holds temporary DRM records used before or instead of protected persistence, in the unable to create inmemorystore object path. Object creation fails before that responsibility can be transferred to a live interface, so later player or server messages are secondary, while tracing unable to create inmemorystore object.

For this object specifically, preserve the owner operation, record identities, lifetime and transition to persistent state, for the unable to create inmemorystore object boundary. A successful fix should create a new in-memory store object and then complete its first real operation, not merely make the factory call return a different generic error, during unable to create inmemorystore object diagnosis.
