ERROR_REPARSE_OBJECT - 755 (0x2F3)
A reparse should be performed by the Object Manager since the name of the file resulted in a symbolic link.
Updated: Feb 21, 2026
Technical Background
The ERROR_REPARSE_OBJECT error code, with the numeric value of 755 and the hexadecimal representation of 0x2F3, is encountered when a file or directory name results in a symbolic link. This error indicates that the Object Manager should perform a reparse operation to handle the symbolic link appropriately.
Error Details
When this error occurs, it signifies that the system has encountered a symbolic link (reparse point) and expects the Object Manager to take specific actions to resolve the reference correctly. Reparse points are special file objects that can be used for various purposes, such as mounting network drives or implementing junctions.
Common Causes
- Invalid Parameter Values: The operation was performed with an invalid parameter value, leading to a symbolic link being encountered where none is expected.
- Incorrect Object Type: The object type of the file or directory does not match expectations, resulting in a symbolic link being present when it should not be.
- Exceeding Limits: In scenarios involving reparse points, certain limits may have been exceeded, leading to unexpected behavior.
Real-World Context
This error can occur during various operations such as file or directory enumeration, file system traversal, or when attempting to open a file that is part of a symbolic link structure. It is important for developers to understand the implications of reparse points and how they affect file system operations.
Is This Error Critical?
The criticality of this error depends on the context in which it occurs. In some cases, such as during normal file operations, it may not be critical. However, if the operation is part of a critical path or involves sensitive data, it could indicate a potential issue that needs to be addressed.
How to Diagnose
To diagnose this error, developers should:
- Review Operation Context: Ensure that the operation context is appropriate for symbolic link handling.
- Validate Parameters: Verify that all parameters passed to file system operations are valid and do not contain unexpected values.
- Confirm Object Types: Check the object types of files or directories involved in the operation to ensure they match expected behavior.
- Verify Input Data: Ensure that input data is correctly formatted and does not include symbolic link references where they should not be present.
How to Resolve
To resolve this error, developers can take the following steps:
- Correct Parameter Usage: Ensure that parameters are used correctly and do not inadvertently introduce symbolic links into operations where they are not expected.
- Adjust Operation Context: Modify the operation context if necessary to handle symbolic links appropriately. This may involve using specific APIs or flags designed for reparse point handling.
- Restore Data: If data corruption is suspected, restore from backups or use system tools to repair file systems and remove any unintended symbolic links.
Developer Notes
Developers should be aware that the presence of reparse points can significantly impact performance and behavior. It is crucial to handle these points correctly to avoid issues such as infinite loops or incorrect data access.
Related Errors
- ERROR_INVALID_PARAMETER: Occurs when a parameter value is invalid, which could lead to encountering symbolic links where they are not expected.
- ERROR_NOT_A_REPARSE_POINT: Indicates that the operation was performed on an object that is not a reparse point, but one was expected.
FAQ
Q: What does ERROR_REPARSE_OBJECT mean?
A: It indicates that a symbolic link (reparse point) has been encountered and requires special handling by the Object Manager.
Q: How can I prevent this error from occurring?
A: Ensure that parameters are valid, object types match expectations, and input data is correctly formatted to avoid unexpected symbolic links.
Summary
The ERROR_REPARSE_OBJECT error code is a specific indication of encountering a symbolic link during file system operations. Understanding its context and implications is crucial for developers working with complex file systems or networked environments. Proper handling of reparse points can prevent issues such as infinite loops or incorrect data access.
