What does HRESULT 0xC00D2766 (NS_E_BACKUP_RESTORE_TOO_MANY_RESETS) mean?

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 decisive 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, when reproducing backup restore too many resets.

For NS_E_BACKUP_RESTORE_TOO_MANY_RESETS, the built-in message summarizes the user-visible outcome, while the symbolic phrase “backup restore too many resets” preserves the exact WMDRM boundary for diagnosis. For this code, the proof step is to record reset history and the original error that caused each reset, within the backup restore too many resets workflow.

Minimum incident record

Capture the first NS_E_BACKUP_RESTORE_TOO_MANY_RESETS occurrence before automatic retry, player teardown, store repair or license reacquisition changes the state, in the backup restore too many resets path. The smallest useful record contains:

• Code-specific proof: record reset history and the original error that caused each reset, while tracing backup restore too many resets.
• Protected identity: backup directory contents and manifest consistency, for the backup restore too many resets boundary.
• Operation state: per-license backup/restore eligibility, during backup restore too many resets diagnosis.
• Persistence or transport: service response, reset count and daily restore limit, in a backup restore too many resets incident.
• Security context: target machine identity and final license-store commit, for this backup restore too many resets result.
• Correlation point: backup or restore operation ID, when reproducing backup restore too many resets.

For the “backup restore too many resets” investigation, use KIDs, license IDs, hashes, certificate thumbprints, sizes and timestamps where possible. While diagnosing NS_E_BACKUP_RESTORE_TOO_MANY_RESETS, do not place content keys, complete license blobs, passwords, cookies or decrypted media in ordinary logs, within the backup restore too many resets workflow.

Why the producing layer matters

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

Triage without destroying evidence

1. Locate the earliest API return, callback or event containing NS_E_BACKUP_RESTORE_TOO_MANY_RESETS and 0xC00D2766.
2. For NS_E_BACKUP_RESTORE_TOO_MANY_RESETS, identify the exact content, license, store, device or migration object generation involved in “backup restore too many resets”.
3. For NS_E_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.
4. Perform the code-specific check: record reset history and the original error that caused each reset, for the backup restore too many resets boundary.
5. Make one narrow correction — stop automated resets and resolve the first failing condition before a later permitted attempt — and repeat the same producing operation, during backup restore too many resets diagnosis.

Why the symbolic name matters

Several values can accompany the “backup restore too many resets” condition in one incident. Order the NS_E_BACKUP_RESTORE_TOO_MANY_RESETS event chain by timestamp and prefer the first code produced at the lowest specific boundary over a later player-level summary, within the backup restore too many resets workflow.

Shortcuts that make diagnosis worse

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

Recovery at the right layer

For NS_E_BACKUP_RESTORE_TOO_MANY_RESETS, the corrective direction is to stop automated resets and resolve the first failing condition before a later permitted attempt, in a backup restore too many resets incident. Preserve the original content/header, store or migration material for NS_E_BACKUP_RESTORE_TOO_MANY_RESETS until the “backup restore too many resets” operation succeeds and survives a fresh application object or required restart.

Representative case: A recovery loop repeatedly resets one restore transaction after the same server error, for this backup restore too many resets result.

Completion criteria

After the repair, recreate the WMDRM object and run the smallest reproducer for NS_E_BACKUP_RESTORE_TOO_MANY_RESETS. Confirm that 0xC00D2766 no longer occurs, that the intended license action completes, and that no store, certificate, clock or migration warning replaces it, when reproducing backup restore too many resets.

Code-specific operational note

The symbolic phrase “backup restore too many resets” is the important search and telemetry key for NS_E_BACKUP_RESTORE_TOO_MANY_RESETS. Keep it beside the exact value 0xC00D2766; the official message “Too many resets in Backup-Restore, within the backup restore too many resets workflow.” is useful to users, but it does not identify the producing API, object generation or protected identity on its own, in the backup restore too many resets path.
