ERROR_DS_DRA_SINK_DISABLED

ERROR_DS_DRA_SINK_DISABLED (8457) is an Active Directory replication error. The destination domain controller is not accepting inbound replication at this time. The state can be intentional during certain maintenance or recovery procedures, but it must be understood before it is changed.

What to check

  • Inspect replication options and Directory Service events on the destination DC.
  • Confirm whether inbound replication was disabled deliberately for maintenance, a restore, or a data-consistency investigation.
  • Do not enable inbound replication blindly if the DC has been offline beyond the replication lifetime or has suspected database divergence.

Useful command

repadmin /options <DestinationDC>
