NS_E_DRM_UNABLE_TO_CREATE_HEADER_OBJECT

The failing WMDRM boundary

0xC00D2757 maps to NS_E_DRM_UNABLE_TO_CREATE_HEADER_OBJECT. Read it as a result from protected content header, keys and cryptographic processing: the DRM runtime cannot create the content-header object required for this operation. Keeping the “unable to create header object” boundary intact for NS_E_DRM_UNABLE_TO_CREATE_HEADER_OBJECT prevents a later playback message from hiding the original DRM failure, within the unable to create header object workflow.

For NS_E_DRM_UNABLE_TO_CREATE_HEADER_OBJECT, the built-in message summarizes the user-visible outcome, while the symbolic phrase “unable to create header 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 header object path.

Place in the DRM workflow

The workflow around NS_E_DRM_UNABLE_TO_CREATE_HEADER_OBJECT matters: a malformed content header, an invalid license XML document and a decryption failure occur at different boundaries and require different replacement artifacts, while tracing unable to create header object. In addition, protected content should be identified by hashes and KIDs in support records; content keys and complete license blobs should not be exposed, for the unable to create header object boundary.

State to capture before retry

Capture the first NS_E_DRM_UNABLE_TO_CREATE_HEADER_OBJECT occurrence before automatic retry, player teardown, store repair or license reacquisition changes the state, during unable to create header object diagnosis. 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, in a unable to create header object incident.
Protected identity: KID, license ID and key-selection result, for this unable to create header object result.
Operation state: algorithm, key length and coding object type, when reproducing unable to create header object.
Persistence or transport: signature or certificate validation status, within the unable to create header object workflow.
Security context: first failing sample offset rather than only the player-level message, in the unable to create header object path.
Correlation point: ASF/DRM header bytes and declared version, while tracing unable to create header object.

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

A useful investigation order

Locate the earliest API return, callback or event containing NS_E_DRM_UNABLE_TO_CREATE_HEADER_OBJECT and 0xC00D2757.
For NS_E_DRM_UNABLE_TO_CREATE_HEADER_OBJECT, identify the exact content, license, store, device or migration object generation involved in “unable to create header object”.
For NS_E_DRM_UNABLE_TO_CREATE_HEADER_OBJECT, determine whether “unable to create header object” occurred before network exchange, during response validation, while enforcing policy, or while committing protected state.
Perform the code-specific check: record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT, during unable to create header object diagnosis.
Make one narrow correction — correct component/version or initialization state and create a fresh content-header object — and repeat the same producing operation, in a unable to create header object incident.

Narrow remediation

For NS_E_DRM_UNABLE_TO_CREATE_HEADER_OBJECT, the corrective direction is to correct component/version or initialization state and create a fresh content-header object, for this unable to create header object result. Preserve the original content/header, store or migration material for NS_E_DRM_UNABLE_TO_CREATE_HEADER_OBJECT until the “unable to create header object” operation succeeds and survives a fresh application object or required restart.

Representative case: The application reaches the content-header stage but object construction fails before any content or server work begins, when reproducing unable to create header object.

Nearby results with different meanings

Result	Different boundary
`NS_E_DRM_UNABLE_TO_CREATE_KEYS_OBJECT`	The DRM runtime cannot create the key-management object required for this operation, during unable to create header object diagnosis.
`NS_E_DRM_UNABLE_TO_CREATE_CODING_OBJECT`	The DRM runtime cannot create the coding object required for this operation, in a unable to create header object incident.
`NS_E_DRM_INVALID_DATA`	Invalid or corrupt data was encountered, for this unable to create header object result.

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

Verification after correction

After the repair, recreate the WMDRM object and run the smallest reproducer for NS_E_DRM_UNABLE_TO_CREATE_HEADER_OBJECT. Confirm that 0xC00D2757 no longer occurs, that the intended license action completes, and that no store, certificate, clock or migration warning replaces it, within the unable to create header object workflow.

What the missing object would have owned

In the NS_E_DRM_UNABLE_TO_CREATE_HEADER_OBJECT path, the content-header object normally parses or constructs DRM header fields such as KID and acquisition metadata, in the unable to create header 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 header object.

For this object specifically, preserve the header version, byte length, KID and license acquisition URL, for the unable to create header object boundary. A successful fix should create a new content-header object and then complete its first real operation, not merely make the factory call return a different generic error, during unable to create header object diagnosis.
