After the job is done, the whole process operates in reverse to send data back to the initiating program. The RPC method is used on most current operating systems. The cause for an RPC error will usually occur on one computer, but the cause may actually be found on an entire network.
When one service on your computer needs to communicate with another, it will contact the RPC server on your computer to initiate the exchange. The RPC server will open up a few ports in order to listen for a message and issue one back.
