NetCopy consists of Client software which runs on OpenVMS and Server software which runs on Windows. The Client software uses standard OpenVMS command syntax for specifying which file are to be copied and whether to copy from OpenVMS to Windows or from Windows to OpenVMS. The Server software consists of a server program which runs as a Windows service and a control program which controls the service and also manages the NetCopy configuration file.  The configuration file describes details of each NetCopy service which runs on the Windows computer. NetCopy Client Program The NetCopy Client program provides an OpenVMS user with commands to copy files between OpenVMS and Windows and also has commands to display a directory list of the files that are present on the Windows computer. NetCopy Windows Service The NetCopy Windows Service communicates with the Client program using TCP/IP.  The Service waits for commands from the Client and then takes appropriate actions based on the commands, such as: • Accept a file from OpenVMS and store it on Windows • Retrieve a file from Windows and send it to OpenVMS • Provide a list of the files which are present on the Windows computer Multiple NetCopy services can be configured to run concurrently in situations where multiple OpenVMS computers are sending files to the Windows computer or where files from different users need to be kept separate. NetCopy Service Control Program The NetCopy Service Control program is a GUI program which makes it easy to configure and control NetCopy services on the Windows computer. The Service Control Program provides configuration and control actions such as: • Add a new service description • Modify a service description • Register and start a service • Stop a service • Display a service log file • Remove a service from Windows
