NS_E_DRM_DATASTORE_CORRUPT
Where the operation stopped
0xC00D2783 maps to NS_E_DRM_DATASTORE_CORRUPT. Read it as a result from local license store, secure store and machine binding: the DRM data store is readable but fails integrity or structure validation. Keeping the “datastore corrupt” boundary intact for it prevents a later playback message from hiding the original DRM failure, during datastore corrupt diagnosis.
The built-in message summarizes the user-visible outcome, while the symbolic phrase “datastore corrupt” preserves the exact WMDRM boundary for diagnosis. For this code, the proof step is to preserve the file, hash, size and first validation failure, in a datastore corrupt incident.
State to capture before retry
Capture the first occurrence before automatic retry, player teardown, store repair or license reacquisition changes the state, for this datastore corrupt result. The smallest useful record contains:
- Code-specific proof: preserve the file, hash, size and first validation failure, when reproducing datastore corrupt.
- Protected identity: license identifier and content key identifier (KID),.
- Operation state: store path, file generation, access result and underlying system error,.
- Persistence or transport: hardware identity and the last hardware or operating-system change, while tracing datastore corrupt.
- Security context: checkpoint, secure-store and registry persistence sequence, for the datastore corrupt boundary.
- Correlation point: first store API call that failed: open, enumerate, save, close or query, during datastore corrupt diagnosis.
For the “datastore corrupt” investigation, use KIDs, license IDs, hashes, certificate thumbprints, sizes and timestamps where possible. While diagnosing this result, do not place content keys, complete license blobs, passwords, cookies or decrypted media in ordinary logs, in a incident.
Place in the DRM workflow
The workflow around this result matters: a license is stored in the protected local license store after acquisition; a store failure is therefore distinct from a server refusing to issue a license, for this datastore corrupt result. In addition, machine-bound state cannot be diagnosed safely by copying store files between computers or by deleting the original before evidence is preserved, when reproducing datastore corrupt.
A useful investigation order
- Start from
0xC00D2783and map it to the first WMDRM object that returned it,. - separate content/header evidence, license evidence, machine/device evidence and service/network evidence around “datastore corrupt”.
- Before retrying this result, check whether another “datastore corrupt” operation was active or whether the previous result may have committed partially.
- preserve the file, hash, size and first validation failure,.
- Apply the smallest supported fix: restore from a supported backup or rebuild/reacquire through supported tooling; avoid resetting unrelated protected state, while tracing datastore corrupt.
Narrow remediation
The supported response to this result is narrow: restore from a supported backup or rebuild/reacquire through supported tooling, for the boundary. After correcting it, reopen or recreate the object that owned “datastore corrupt” so cached state from the failed generation is not mistaken for the repair result.
Representative case: A partial disk restore leaves a truncated DRM store generation, during datastore corrupt diagnosis.
What not to do first
- Avoid deleting or resetting DRM state before recording hashes, timestamps and the first store error, in a incident. That changes evidence without demonstrating why it was produced.
- Avoid copying a protected license store from another computer as a repair, for this datastore corrupt result. That shortcut can create a second store, identity or policy problem, when reproducing datastore corrupt.
- Do not reduce it to “DRM failed” in telemetry; retain the HRESULT, symbolic name, operation and object identity,.
Nearby results with different meanings
| Result | Different boundary |
|---|---|
NS_E_DRM_UNABLE_TO_OPEN_DATA_STORE | The DRM data-store file cannot be opened,. |
NS_E_DRM_UNABLE_TO_LOAD_HARDWARE_ID | The DRM subsystem cannot obtain the machine identity used for protected-state binding, while tracing datastore corrupt. |
NS_E_DRM_CHECKPOINT_FAILED | The secure-state checkpoint cannot be created or committed, for the boundary. |
Several values can accompany the “datastore corrupt” condition in one incident. Order the result event chain by timestamp and prefer the first code produced at the lowest specific boundary over a later player-level summary, during datastore corrupt diagnosis.
Verification after correction
A valid regression for it has two fixtures: one that deliberately produces “the DRM data store is readable but fails integrity or structure validation” and one that applies the targeted correction, in a incident. Compare callback order, selected license/KID, final rights decision and persistence state; disappearance of the “datastore corrupt” dialog alone is not proof.
Code-specific operational note
The symbolic phrase “datastore corrupt” is the important search and telemetry key for it. Keep it beside the exact value 0xC00D2783; the official message “The Digital Rights Management data storage is not functioning properly, for this datastore corrupt result. Contact Microsoft product support, when reproducing datastore corrupt.” is useful to users, but it does not identify the producing API, object generation or protected identity on its own,.
