ERROR_DS_CANT_RETRIEVE_CHILD

ERROR_DS_CANT_RETRIEVE_CHILD (8422) is an Active Directory Domain Services error. The operation expected a child object below a known parent but could not retrieve it. The cause can be an incorrect DN, an object that was moved or deleted, insufficient access, replication divergence, or a directory read failure.

What to check

  • Verify the parent DN and enumerate direct children on the same DC that returned the error.
  • Compare the object state on replication partners if the child should exist.
  • Review Directory Service events for an underlying database, access, or replication message.
