If an error occurs in a Transmit pipeline, such as a Scriptor component with a scripting error, the pipeline returns both an error value and an error description string, such as
80020101: Component Execution failed for component ProgID.Scriptor
If an error is generated in this Receive pipeline on a remote computer, this error is logged to the event log of the remote computer, and the error number is returned to the calling component in the Transmit pipeline.
The error returned by the pipeline may contain sensitive information which should remain in the control of the hosting operation. For this reason, when an error occurs in a Receive pipeline, the error description string is not returned to the Transmit pipeline.
