Debugging Service Applications 

You can debug service applications by attaching to the service application process when it is already running (that is, by starting the service first, and then attaching to the debugger). To attach to the service application process, choose RunAttach To Process, and select the service application in the resulting dialog.
In some cases, this approach may fail, due to insufficient rights. If that happens, you can use the Service Control Manager to enable your service to work with the debugger: 

Service Applications 

Service applications take requests from client applications, process those requests, and return information to the client applications. They typically run in the background, without much user input. A Web, FTP, or e-mail server is an example of a service application. 

Service Name Properties 

The VCL provides classes for creating service applications on the Windows platform (not available for cross-platform applications). These include TService and TDependency. When using these classes, the various name properties can be confusing. This topic describes the differences.
Services have user names (called Service start names) that are associated with passwords, display names for display in manager and editor windows, and actual names (the name of the service). Dependencies can be services or they can be load ordering groups. They also have names and display names. And because service objects are derived from TComponent, they inherit the Name... more 

Service Threads 

Each service has its own thread (TServiceThread), so if your service application implements more than one service you must ensure that the implementation of your services is thread-safe. TServiceThread is designed so that you can implement the service in the TServiceOnExecute event handler. The service thread has its own Execute method which contains a loop that calls the service's OnStart and OnExecute handlers before processing new requests.
Because service requests can take a long time to process and the service application can receive simultaneous requests from more than one client, it is more efficient to spawn a new thread... more
