ERROR_DS_NO_REF_DOMAIN - 8575 (0x217F)
Unable to find a valid security descriptor reference domain for this partition.
Updated: Feb 21, 2026
Technical Meaning
This error code indicates that the system was unable to locate a valid security descriptor reference domain for the specified partition. A security descriptor is an object that contains information about the access control and ownership of a resource, such as a file or directory.
Error Details
The ERROR_DS_NO_REF_DOMAIN error typically occurs in scenarios where Active Directory operations are performed, particularly when dealing with partitions within the directory service. The reference domain is crucial for determining the security context under which an operation should be executed. If no valid reference domain can be found, the operation cannot proceed as intended.
Usage Context
This error is most commonly encountered in enterprise environments where Active Directory is used to manage user and group permissions across multiple domains or partitions. It may also appear during administrative tasks that require specific security contexts.
Developer Interpretation
When encountering ERROR_DS_NO_REF_DOMAIN, developers should consider the following:
- Verify that all necessary domain references are correctly configured in the directory service.
- Ensure that the operation being performed is within the scope of a valid security descriptor reference domain.
- Check for any misconfigurations or inconsistencies in the Active Directory structure that might prevent the system from identifying a suitable reference domain.
Related Errors

FAQ
Q: What does ERROR_DS_NO_REF_DOMAIN mean?
A: It indicates that no valid security descriptor reference domain could be found for the specified partition. This is often related to Active Directory operations and can affect access control settings.
Q: How do I resolve this error?
A: Review your Active Directory configuration, ensure all necessary domains are correctly set up, and verify that the operation context aligns with a valid security descriptor reference domain.
Summary
ERROR_DS_NO_REF_DOMAIN is an important diagnostic code for developers working with Active Directory. It highlights issues related to security descriptors and partition references, which can impact access control operations. Proper configuration and validation of directory service settings are key to resolving this error.
