NS_E_DRM_INVALID_SECURESTORE_PASSWORD
What NS_E_DRM_INVALID_SECURESTORE_PASSWORD means
NS_E_DRM_INVALID_SECURESTORE_PASSWORD is Windows Media DRM HRESULT 0xC00D2751. Its symbolic name identifies a secure-store password validation failure. Microsoft’s public error table exposes only a generic DRM support message for this code, so diagnosis has to retain the exact API and secure-store operation that produced it.
What to check
- Record the first store, backup, restore, or protected-state API that returned
0xC00D2751. - Keep the backup/restore operation ID, target machine identity, store generation, and any preceding integrity or authentication result. Do not log the password, license keys, or decrypted content.
- Do not merge backup sets from different machines or invent request identifiers. Machine-bound DRM state and anti-abuse counters can make a copied store unusable even when its files are readable.
Recovery
Use the supported backup/restore or license reacquisition path for the same machine and operation. Retry only after the secure-store credentials/state have been corrected or a supported new store has been established; repeating the same request with unchanged protected state is not a repair.
Related HRESULTs
NS_E_DRM_SECURE_STORE_NOT_FOUND means the required secure-store state could not be found, while NS_E_BACKUP_RESTORE_BAD_DATA identifies malformed restore data. Those conditions should not be collapsed into a password-validation failure.
