ERROR_DS_CLASS_NOT_DSA - 8343 (0x2097)
The object must be of class DSA.
Updated: Feb 21, 2026
Technical Meaning
The error code ERROR_DS_CLASS_NOT_DSA (0x2097) indicates that an operation was attempted on a directory service object, but the object does not belong to the Directory Service Agent (DSA) class. This error is specific to operations within the context of Active Directory or LDAP directories.
Error Details
This error typically occurs when a method or function expects an object of a particular class (DSA), but encounters an object that does not match this requirement. The DSA class in directory services refers to objects that are responsible for managing and maintaining the directory information, such as domain controllers in Active Directory.
Usage Context
This error is relevant in scenarios where operations require specific types of objects within a directory service context. For example, certain administrative tasks or queries may only be valid on DSA-class objects.
Developer Interpretation
When encountering this error, developers should ensure that the object being operated upon matches the expected class type. This involves verifying the object's class attribute and ensuring that operations are performed in an appropriate context where such objects are expected to exist.
Related Errors

FAQ
Q: What does the error code 8343 mean?

Q: How can I resolve this issue?
A: Ensure that the object being operated upon is of the correct class (DSA) and that the operation context is appropriate for such objects.
Summary
The ERROR_DS_CLASS_NOT_DSA error indicates a mismatch between the expected DSA-class object and the actual object encountered during directory service operations. Developers should verify object classes and ensure proper operation contexts to avoid this issue.
