The PowerShare error code 83 is an internal error: rServerNumbersSame. Somehow two replicas of the Folder Directory (dNode #2) are using the same server number (which forms the top half of creationIDs). This is a bad error which causes the replication between the two replicas to fail.
To fix the error, a user should remove the copy of the folder directory from the server reporting the error. Then re-create the copy once the server log indicates that the removal has completed successfully.
