ERROR_DS_AUDIT_FAILURE - 8625 (0x21B1)

A required audit event could not be generated for the operation.

Updated: Feb 21, 2026

Technical Background

The ERROR_DS_AUDIT_FAILURE error code, with the numeric value 8625 and hexadecimal representation 0x21B1, indicates that a required audit event could not be generated for the operation. This error is specific to scenarios where Windows attempts to generate an audit log entry but fails due to various potential issues.

Error Details

The ERROR_DS_AUDIT_FAILURE error typically occurs in environments with auditing enabled on Active Directory services or when certain operations are being logged by the system. The failure can be attributed to several factors, such as insufficient permissions, resource limitations, or operational constraints.

Common Causes

  • Insufficient Permissions: The user or process attempting the operation may not have the necessary privileges to generate an audit event.
  • Resource Limitations: The system might be experiencing high load, preventing the generation of additional log entries.
  • Operational Constraints: Certain operations might inherently fail to generate audit events due to design limitations.

Real-World Context

This error is commonly encountered in enterprise environments where detailed logging and auditing are critical for security and compliance. Administrators may receive this error when performing actions such as user account management, group policy updates, or other administrative tasks that require logging.

Is This Error Critical?

The severity of the ERROR_DS_AUDIT_FAILURE can vary depending on the context in which it occurs. While it does not directly impact system functionality, failing to log critical operations could compromise security and auditing capabilities. Therefore, it is essential to address this error promptly to ensure comprehensive logging.

How to Diagnose

To diagnose ERROR_DS_AUDIT_FAILURE, follow these steps:

  1. Review Operation Context: Determine the specific operation that triggered the error.
  2. Validate Parameters: Ensure all parameters passed to the operation are valid and correctly formatted.
  3. Confirm Object Types: Verify that the objects involved in the operation (e.g., users, groups) have the expected types and permissions.

How to Resolve

To resolve ERROR_DS_AUDIT_FAILURE, consider the following actions:

  • Correct Parameter Usage: Ensure all parameters are correctly set and meet the required criteria.
  • Adjust Operation Context: Modify the environment or context in which the operation is being performed to ensure it aligns with logging requirements.
  • Restore Data: If data corruption is suspected, restore from a backup if available.

Developer Notes

Developers should be aware that this error can occur due to various factors and may require additional context for troubleshooting. It is advisable to implement robust logging mechanisms and handle such errors gracefully in applications interacting with the Windows API.

Related Errors

  • ERROR_DS_OBJECT_NOT_FOUND: Occurs when an object cannot be located, which might prevent audit events from being generated.
  • ERROR_DS_DRA_SCHEMA_MISMATCH: Indicates a schema mismatch that could affect auditing operations.

FAQ

Q: What does the ERROR_DS_AUDIT_FAILURE error mean?

A: It indicates that a required audit event could not be generated for the operation due to various potential issues such as insufficient permissions or resource limitations.

Q: How can I prevent this error from occurring?

A: Ensure that all operations are performed with appropriate permissions and that the system resources are sufficient to handle logging requirements.

Summary

The ERROR_DS_AUDIT_FAILURE is a specific error indicating an issue in generating audit events. Understanding its causes, diagnosing it correctly, and resolving it effectively can help maintain comprehensive security and auditing capabilities in Windows environments.
