The ERROR_DS_DRA_RPC_CANCELLED error code indicates that a remote procedure call (RPC) used for replication in the directory service has been cancelled. This typically occurs when an operation intended to replicate data between two or more directory service instances is interrupted before completion.
Error Details
This error suggests that there was an attempt to perform a replication task, but the process was terminated prematurely. The cancellation could be due to various reasons such as network issues, system shutdowns, or other external factors that caused the RPC call to be interrupted.
Usage Context
The ERROR_DS_DRA_RPC_CANCELLED error is relevant in scenarios where directory service replication is being managed and monitored. It can appear when using tools like dcpromo, repadmin, or other administrative utilities that handle replication tasks between domain controllers.
Developer Interpretation
When encountering this error, developers should consider the context of the operation and verify if any external factors might have caused the cancellation. This could include checking network connectivity, ensuring no system interruptions occurred during the operation, and validating the parameters passed to the RPC call.
