There are service applications and service drivers, the latter are obviously running at a lower level but can not be created using Delphi. Service applications are no different to interactive applications, except for recognising extra control messages. But if they misbehave on start-up, Windows will wait 30 seconds or more for a response delaying the boot process. If other services are dependent on ones that won't start, they won't run either. The worst case I've seen was two years ago when a Sun Java runtime timebomb (an expired certificate) caused any programs needed the runtime to hang, including the APC power management drivers used to power down PCs when batteries are failing, which somehow caused several other services to die, in thousands of servers around the world, on the same day. Moral is never trust any program dependencies, runtimes in particular, like Java, Perl or .net.
