A client sends a message to a server computer system over a network. Upon receiving the message either from the client or from a local process, the server passes the message down through a software stack to a lower layer module that is capable of detecting errors in the message. That lower layer module then detects an error and inserts error information that represents the error into an error reporting data structure. The lower layer also inserts potential text remedy information on how to correct the error. The module that detected the error then returns and passes the error reporting data structure back up through the software stack. The server then sends the response to the message along with the text field that includes the text error information back to the client computing system or other local requesting process.
