Windows shutdown time Fluctuates

Archived from groups: microsoft.public.win2000.setup_deployment (More info?)

Hi,
The Windows shutdown time Fluctuates depending on how
long the System running independent of the other
Applications running on the system.

For Example:

1> If the System runs for 10 minutes after boot up it
takes 10 Seconds to shutdow.

2> If the system runs for 3 hours it takes around 25 sends
to shutdown

3> If the System runs for 2 to 3 days it takes around 1
minute to shutdown

Let me know if there is any setting or configration I can
change so the shutdown time doesn't vary much.

OR What are the factors involved to drastically changes
the shutdown time.

Thanks,
Madhava
