Technical Meaning
The error code ERROR_DS_OBJ_CLASS_VIOLATION with the numeric value 8212 and hexadecimal representation 0x2014 indicates that a requested operation failed because it did not meet one or more constraints associated with the class of the object being operated upon. This typically occurs in directory service operations, where the object's class does not support the specific action attempted.
Error Details
This error is specific to certain operations within the Windows Directory Services (DS) framework. It suggests that an attempt was made to perform an operation on an object that is not compatible with its defined class or schema. For example, trying to modify a property of an object that does not support such modifications would trigger this error.
Usage Context
This error can occur in various scenarios where directory service operations are performed, such as modifying attributes of objects within Active Directory. It is important for developers and administrators to understand the constraints associated with different object classes to avoid encountering this error.
Developer Interpretation
When encountering ERROR_DS_OBJ_CLASS_VIOLATION, it indicates that the operation attempted on an object did not conform to its class definition or schema.
