ERROR_DS_DRA_CONNECTION_FAILED

ERROR_DS_DRA_CONNECTION_FAILED (8444) is an Active Directory replication error. The destination could not contact the source domain controller selected for replication. Start with the specific partner and the RPC/DNS path between the two domain controllers.

What to check

Use repadmin /showrepl to confirm the source DC, destination DC, and naming context that failed.
Verify name resolution and RPC reachability between those two domain controllers, including the target DC service state.
Compare the failure across other partners; a single bad connection object and a site-wide DNS or network problem require different remediation.

Useful command

repadmin /showrepl <DestinationDC> /all /verbose
