ERROR_DS_CANT_RETRIEVE_SD
ERROR_DS_CANT_RETRIEVE_SD (8526) is an Active Directory Domain Services error. The operation required an Active Directory security descriptor but the directory service could not retrieve it. The cause may be an access-control issue, a problematic object record, or a broader AD DS health problem on the serving DC.
What to check
- Identify the exact object and DC involved, then check whether other privileged reads of that object also fail.
- Review Directory Service events and verify AD DS health before attempting ACL remediation.
- Avoid broad ACL resets; they can hide the fault and change delegated administration unexpectedly.
