Summary
Direct input from and to a service from any user has to be designed carefully.
System output from a service to the desktop or workstation should be limited to situations with interactive users or imperative system events that must be visible to administrators.
When a service has privileges to interact with the desktop, any messages, boxes, or windows that require user interaction can be extremely dangerous if no user is currently logged on, or a user is logged on but away from his desk.
Never use forms in your services—they are never a supported strategy. User feedback should be provided through other notification channels such as the NT Event Log, Simple Network Management Protocol, SQL Server, SMTP, or any other logging mechanism.
