Active Directory Replication
Active Directory replication failed because the remote procedure call failed and did not execute
The replication generated an error (1727): The remote procedure call failed and did not execute.
Active Directory replication reached the RPC layer but the remote call still failed before the operation could complete successfully.
Observed message
The replication generated an error (1727): The remote procedure call failed and did not execute.
Why it happens
- RPC communication started but failed before the replication operation could finish.
- A transient network interruption or service failure broke the call.
- The source or destination domain controller is unstable or under service pressure.
How to fix it
- Check RPC service status and general health on the affected domain controllers.
- Review network reliability, latency, and any intermittent filtering between controllers.
- Inspect system, directory service, and replication logs around the time of failure.
