Hard Drives always boot up “Shared”

My computer has three OSs. Win98, NT & Win2K.
This all works under system comander. All works very well except each time I boot up in NT4 SP5 all my Hard Drives show up with the little “Share Hand”. I enter the properties of each drive and remove the shared status and select “Apply” and all is well until next boot up. The machine is not connected to a network. Does anyone know if I can write a bootup script to prevent the “Sharing”. Or is there some other method to removing the “Share” so it does not deploy at each boot. At this time this does not present any problems. I would like to know how control this and prevent it from happening.
