NT Service on system shutdown

[Scott Wolfington]

Hi!

Is there an equivalent to %SERVICE_STOP_PENDING for the
%SERVICE_CONTROL_SHUTDOWN NT service control? Maybe something like
%SERVICE_SHUTDOWN_PENDING? I'm trying to clean things up nicely
in this service I'm writing when the OS shuts down and my
service is still running. I'm getting through my %SERVICE_CONTROL_SHUTDOWN
logic in my service handler, but the service automatically
shuts down after about 20-21 seconds, even though it could
take me up to 60 seconds to clean things up. I've tested this
by looping for 60 seconds within this logic before continuuing
but it still shuts down after 20 seconds. I've also tried setting
the dwWaitHint value to 60 seconds.

Thanks,
Scott

From win32 helpfile:
When the user shuts down the system, all control handlers receive the
SERVICE_CONTROL_SHUTDOWN control code. They are notified in the order that
they appear in the database of installed services. By default, a service
has approximately 20 seconds to perform cleanup tasks before the system
shuts down. However, if the system is left in the shutdown state (not restarted
or powered down) the service continues to run.
You can change the time the system will wait for service shutdown by modifying
the WaitToKillServiceTimeout value in the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control

Hi Peter,

I saw that WaitToKillServiceTimeout reg setting too. I really
want to refrain from making any registry changes though. Maybe
I should just try to come up with a way to insure that my service has
done everything it needs to do within that 20 second shutdown
window. On most occassions (95-97% of the time) the service will
be done wrapping things up within that 20 seconds. I'm still
open to ideas though.
