The guardian runs as a service under NT. I have no idea why instsvc doesn't
install it, too, but someone noticed in our early betas that FB didn't put a
GuardianOptions key in the registry. I thought a person named Marcel was
rebuilding with Delphi the GUI program that's called IB Services Manager in
IB6.

Only in W2K and XP, not before.

That's the location for Win95 at least.

That's the location for NT and I think W2k and XP preserve it.

In NT there are fours cases, since the engine may be running as an
application (what I use for myself on NT4), the guardian may be running as
an application, the engine may be running as a service or the guardian may
be running as a service. Of course, under typical circumstances, the
guardian running means the engine is running, too. To stop a service from
the command-line, you use the
NET STOP "service name"
command and you probably already know how to stop the engine or the guardian
running as applications.

If you don't like NET STOP, you can call the NT API for Services or may use
the WMI (Windows Management Instrumentation). If WMI can control and query
the IIS, it can query and control any service:

and click on "Services".
