NS_E_BACKUP_RESTORE_TOO_MANY_RESETS
How to classify this result
When the client returns NS_E_BACKUP_RESTORE_TOO_MANY_RESETS (0xC00D2766), the relevant condition is the backup/restore workflow exceeded its permitted reset count. 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.
Record reset history and the original error that caused each reset.
Minimum incident record
The smallest useful record contains:
- Code-specific proof: record reset history and the original error that caused each reset.
- Protected identity: backup directory contents and manifest consistency.
- Operation state: per-license backup/restore eligibility.
- Persistence or transport: service response, reset count and daily restore limit.
- Security context: target machine identity and final license-store commit.
- Correlation point: backup or restore operation ID.
Why the producing layer matters
Two platform rules frame this result. 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
- Locate the earliest API return, callback or event containing this result and
0xC00D2766. - Identify the exact content, license, store, device or migration object instance involved in “backup restore too many resets”.
- Determine whether “backup restore too many resets” occurred before network exchange, during response validation, while enforcing policy, or while committing protected state.
- Perform the code-specific check: record reset history and the original error that caused each reset.
- Make one targeted change — stop automated resets and resolve the first failing condition before a later permitted attempt — and repeat the same producing operation.
Why the symbolic name matters
| Result | Different condition |
|---|---|
NS_E_DRM_RESTORE_FRAUD | The restoration request is rejected by anti-abuse or restore-limit logic. |
NS_E_DRM_INVALID_SECURESTORE_PASSWORD | Secure-store password validation failed. |
NS_E_BACKUP_RESTORE_BAD_DATA | Backup/restore data fails format or integrity validation. |
Shortcuts that make diagnosis worse
- Avoid merging files from different backup sets or inventing request identifiers.
- Avoid repeatedly resetting or restoring until anti-fraud limits are reached.
Recovery at the right layer
To correct this, stop automated resets and resolve the first failing condition before a later permitted attempt.
Representative case: A recovery loop repeatedly resets one restore transaction after the same server error.
Completion criteria
After the repair, recreate the WMDRM object and run the smallest reproducer. Confirm that 0xC00D2766 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 user-facing message “Too many resets in Backup-Restore.” describes the visible condition but does not identify the producing API, object instance, or protected identity by itself.
