ERROR_DS_DRA_SOURCE_REINSTALLED - 8459 (0x210B)

The replication source has been reinstalled.

Updated: Feb 21, 2026

Technical Background

The error code ERROR_DS_DRA_SOURCE_REINSTALLED (0x210B) is a specific error encountered in the context of directory service replication within Windows systems. This error indicates that the replication source has been reinstalled, which can lead to disruptions or inconsistencies in the replicated data.

Error Details

The term 'replication' refers to the process by which changes made to one directory are propagated to other directories. In this case, the source of such a replication operation has undergone a reinstall, potentially leading to issues with ongoing or pending replication tasks.

Common Causes

  • Invalid Parameter Values: Incorrect parameters passed during the replication process could lead to this error if they do not align with the state of the reinstalled source.
  • Incorrect Object Type: The object type being replicated might be misidentified, causing the system to recognize the reinstall as an unexpected event.

    Real-World Context

    This error typically occurs in environments where directory service replication is critical for maintaining data consistency across multiple servers. It can affect Active Directory and other directory services that rely on replication for synchronization.

    Is This Error Critical?

    The severity of this error depends on the state of the replication process at the time of the reinstall. If ongoing replication tasks are interrupted, it could lead to data inconsistencies or service disruptions until the replication is resumed or reinitialized.

    How to Diagnose

    1. Review Operation Context: Examine the context in which the replication operation was initiated and ensure that all parameters were correctly specified.
    2. Validate Parameters: Verify that the parameters passed during the replication process are valid and consistent with the state of the source after its reinstall.
    3. Confirm Object Types: Ensure that the object types being replicated are accurately identified to avoid misinterpretation by the system.
    4. Verify Input Data: Check for any corrupted or invalid data that might have been introduced during the reinstall process, which could affect replication.

      How to Resolve

    5. Correct Parameter Usage: Adjust the parameters used in the replication operation to ensure they are valid and consistent with the state of the reinstalled source.
    6. Adjust Operation Context: Modify the context or environment in which the replication is being performed if necessary, ensuring it aligns with the current state of the directory service.
    7. Restore Data: If data corruption is suspected due to the reinstall, restore from a backup to ensure integrity before attempting replication again.
    8. Retry Operation with Valid Inputs: Once parameters and context are validated, retry the replication operation to ensure successful completion.

      Developer Notes

      Developers should be aware of the potential for this error in scenarios involving directory service replication, especially when dealing with reinstalled sources or updated configurations that could affect ongoing operations.
