NS_E_DRM_RESTORE_FRAUD
The exact DRM condition
NS_E_DRM_RESTORE_FRAUD is Windows Media DRM HRESULT 0xC00D2753. It identifies the restoration request is rejected by anti-abuse or restore-limit logic. The useful scope is the backup/restore workflow that enumerates eligible licenses, writes a backup set, sends restoration requests to the license-management service and reconciles restored state with the target machine; it is not a generic statement that the media player, network or file system failed, for this restore fraud result.
For NS_E_DRM_RESTORE_FRAUD, the built-in message summarizes the user-visible outcome, while the symbolic phrase “restore fraud” preserves the exact WMDRM boundary for diagnosis. For this code, the proof step is to record service response, restore history and target identity without attempting to bypass the limit, when reproducing restore fraud.
The surrounding protocol and store state
Only licenses carrying the backup/restore right are eligible, and licenses with secure state can be intentionally excluded by the issuer, within the restore fraud workflow. For NS_E_DRM_RESTORE_FRAUD, backup and restore are multi-stage asynchronous operations; one damaged member or a stale request identifier is not equivalent to an unavailable service, in the restore fraud path.
Evidence worth preserving
Capture the first NS_E_DRM_RESTORE_FRAUD occurrence before automatic retry, player teardown, store repair or license reacquisition changes the state, while tracing restore fraud. The smallest useful record contains:
- Code-specific proof: record service response, restore history and target identity without attempting to bypass the limit, for the restore fraud boundary.
- Protected identity: target machine identity and final license-store commit, during restore fraud diagnosis.
- Operation state: backup or restore operation ID, in a restore fraud incident.
- Persistence or transport: backup directory contents and manifest consistency, for this restore fraud result.
- Security context: per-license backup/restore eligibility, when reproducing restore fraud.
- Correlation point: service response, reset count and daily restore limit, within the restore fraud workflow.
For the “restore fraud” investigation, use KIDs, license IDs, hashes, certificate thumbprints, sizes and timestamps where possible. While diagnosing NS_E_DRM_RESTORE_FRAUD, do not place content keys, complete license blobs, passwords, cookies or decrypted media in ordinary logs, in the restore fraud path.
Related codes and the diagnostic split
| Result | Different boundary |
|---|---|
NS_E_DRM_INVALID_SECURESTORE_PASSWORD | The invalid securestore password operation failed at its documented DRM boundary, while tracing restore fraud. |
NS_E_BACKUP_RESTORE_BAD_DATA | Backup/restore data fails format or integrity validation, for the restore fraud boundary. |
NS_E_DRM_BACKUPRESTORE_BUSY | A backup or restore operation is already active, during restore fraud diagnosis. |
Several values can accompany the “restore fraud” condition in one incident. Order the NS_E_DRM_RESTORE_FRAUD event chain by timestamp and prefer the first code produced at the lowest specific boundary over a later player-level summary, in a restore fraud incident.
Diagnostic sequence
- Preserve
NS_E_DRM_RESTORE_FRAUD, the calling interface and the first lower-level status before a wrapper replaces it, for this restore fraud result. - Correlate
NS_E_DRM_RESTORE_FRAUDwith one KID/license ID, content hash, device certificate or migration operation ID for the “restore fraud” path. - For
NS_E_DRM_RESTORE_FRAUD, reconstruct the state transition immediately preceding “restore fraud” instead of starting from the final player dialog. - Prove the boundary by ensuring you can record service response, restore history and target identity without attempting to bypass the limit, when reproducing restore fraud.
- After you follow the issuer/service-supported restore policy or obtain new rights, verify both the requested right and the final store/device state, within the restore fraud workflow.
Correcting the producing condition
Resolve NS_E_DRM_RESTORE_FRAUD at its producing boundary: follow the issuer/service-supported restore policy or obtain new rights, in the restore fraud path. For NS_E_DRM_RESTORE_FRAUD, a player reinstall, reboot or new license request is useful only when it changes the “restore fraud” boundary and can be verified against the original evidence.
Representative case: Repeated restoration attempts for the same protected rights trigger fraud controls, while tracing restore fraud.
Actions that do not prove a fix
- Avoid repeatedly resetting or restoring until anti-fraud limits are reached, for the restore fraud boundary. That changes evidence without demonstrating why
NS_E_DRM_RESTORE_FRAUDwas produced. - Avoid merging files from different backup sets or inventing request identifiers, during restore fraud diagnosis. For
NS_E_DRM_RESTORE_FRAUD, that shortcut can create a second store, identity or policy problem, in a restore fraud incident. - Do not reduce
NS_E_DRM_RESTORE_FRAUDto “DRM failed” in telemetry; retain the HRESULT, symbolic name, operation and object identity, for this restore fraud result.
Regression check
Repeat the operation that originally returned NS_E_DRM_RESTORE_FRAUD. For NS_E_DRM_RESTORE_FRAUD, assert the exact HRESULT at the producing API in the failing “restore fraud” 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_RESTORE_FRAUD, verify the requested action and the final license-store, secure-clock, device or migration state relevant to “restore fraud”.
Code-specific operational note
The symbolic phrase “restore fraud” is the important search and telemetry key for NS_E_DRM_RESTORE_FRAUD. Keep it beside the exact value 0xC00D2753; the official message “You cannot restore your license(s), when reproducing restore fraud.” is useful to users, but it does not identify the producing API, object generation or protected identity on its own, within the restore fraud workflow.
