What does HRESULT 0xC00D2751 (NS_E_DRM_INVALID_SECURESTORE_PASSWORD) mean?

NS_E_DRM_INVALID_SECURESTORE_PASSWORD

How to classify this result

When the client returns NS_E_DRM_INVALID_SECURESTORE_PASSWORD (0xC00D2751), the decisive condition is the invalid securestore password operation failed at its documented DRM boundary. This result belongs to license backup, restore and anti-abuse state, specifically 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.

The built-in message summarizes the user-visible outcome, while the symbolic phrase “invalid securestore password” preserves the exact WMDRM boundary for diagnosis. For this code, the proof step is to record the exact API, object state, input identity and first lower-level result associated with invalid securestore password.

Minimum incident record

Capture the first NS_E_DRM_INVALID_SECURESTORE_PASSWORD occurrence before retry or teardown changes state. The smallest useful record contains:

• Code-specific proof: record the exact API, object state, input identity and first lower-level result associated with invalid securestore password.
• Protected identity: backup or restore operation ID.
• Operation state: backup directory contents and manifest consistency.
• Persistence or transport: per-license backup/restore eligibility.
• Security context: service response, reset count and daily restore limit.
• Correlation point: target machine identity and final license-store commit.

Prefer IDs, hashes, sizes, and timestamps. Never log keys, passwords, licenses, or decrypted media.

Why the producing layer matters

Two platform rules frame NS_E_DRM_INVALID_SECURESTORE_PASSWORD. Only licenses carrying the backup/restore right are eligible, and licenses with secure state can be intentionally excluded by the issuer. Backup and restore are multi-stage asynchronous operations; one damaged member or a stale request identifier is not equivalent to an unavailable service.

Triage without destroying evidence

1. Locate the earliest API return, callback or event containing NS_E_DRM_INVALID_SECURESTORE_PASSWORD and 0xC00D2751.
2. Identify the exact content, license, store, device or migration object generation involved in “invalid securestore password”.
3. Determine whether “invalid securestore password” occurred before network exchange, during response validation, while enforcing policy, or while committing protected state.
4. Perform the code-specific check: record the exact API, object state, input identity and first lower-level result associated with invalid securestore password.
5. Make one narrow correction — correct the producing DRM state or input and retry with a fresh operation object — and repeat the same producing operation.

Why the symbolic name matters

Order the NS_E_DRM_INVALID_SECURESTORE_PASSWORD event chain by timestamp; prefer the earliest specific result.

Shortcuts that make diagnosis worse

• Avoid merging files from different backup sets or inventing request identifiers. That changes evidence without demonstrating why NS_E_DRM_INVALID_SECURESTORE_PASSWORD was produced.
• Avoid repeatedly resetting or restoring until anti-fraud limits are reached. That shortcut can create a second store, identity or policy problem.
• Do not reduce NS_E_DRM_INVALID_SECURESTORE_PASSWORD to “DRM failed” in telemetry; retain the HRESULT, symbolic name, operation and object identity.

Recovery at the right layer

The corrective direction is to correct the producing DRM state or input and retry with a fresh operation object. Preserve the original content/header, store or migration material for NS_E_DRM_INVALID_SECURESTORE_PASSWORD until the operation succeeds and survives a fresh application object or required restart.

Representative case: The application reaches the invalid securestore password path and receives this exact HRESULT before the higher-level media action can complete.

Completion criteria

After the repair, recreate the WMDRM object and run the smallest reproducer for NS_E_DRM_INVALID_SECURESTORE_PASSWORD. Confirm that 0xC00D2751 no longer occurs, that the intended license action completes, and that no store, certificate, clock or migration warning replaces it.

Code-specific operational note

The symbolic phrase “invalid securestore password” is the important search and telemetry key for NS_E_DRM_INVALID_SECURESTORE_PASSWORD. Keep it beside the exact value 0xC00D2751; the official message “A problem has occurred in the Digital Rights Management component. Contact Microsoft product support.” is useful to users, but it does not identify the producing API, object generation or protected identity on its own.
