Function Description: This function calls AddPerMachineConnection API. If the call fails

Parameters: pServer,pPrinterName,pPrintServer,pProvider - arguments for the

            bQuiet - flag for quiet mode. This is set if /q option is used.

Return Value: NONE.

Parameters: pServer - pointer to the name of the machine on which the per machine connections
                      are to be enumerated.
            pszFileName - pointer to the file name where the connection data is to be dumped.
