ERROR_DS_DRA_MISSING_PARENT

ERROR_DS_DRA_MISSING_PARENT (8460) is an Active Directory replication error. The destination cannot apply a child-object update because the required parent is absent. This can be caused by replication divergence, deletion history, or stale data on a partner.

What to check

Identify the missing parent and child DNs from the replication and Directory Service logs.
Check whether the parent was deleted, moved, or is present on a healthy reference domain controller.
Assess for lingering objects or a stale partner before attempting to recreate directory objects manually.

Useful command

repadmin /showobjmeta <ReferenceDC> "<ParentDistinguishedName>"
