PBService Overview

Windows NT Services

Windows NT Services are RPC enabled Win32 programs that are treated specially by NT. NT can automatically start the Service program (before anyone's logged on). It provides a unified and secure means of controlling Win32 services, via the Service Control Manager, and also provides the APIs to remotely control the Service.

NT Services are ideal for performing work for various clients, both local and remote. NT is delivered with a number of Services like the Scheduler and Print Spooler. In PowerBuilder applications Services are ideal as Report Generators, Data Analysis programs, backup utilities, etc.
