  Turning off everything you don't use will help, that's one of the =
basic principles of securing a machine. Instead of blocking ports turn = off
what's holding them open and there is less to hack at. Think of it = like a
building with doors and windows, it's easier to secure if there = are less
doors and windows than if there are more. So yes, if you don't = use
filesharing then by all means turn it off and you are more secure.

  However eliminating 1 out of 6 doors, especially a door that is locked =
by default and uses a magnetic keycard to open, isn't going to make that = much
difference. It would make more difference to use good passwords (a = keycard
that is tougher to crack).

  If you sit behind NAT or run a firewall that blocks inbound attempts, =
it makes even less difference.

    So you would say it could help, but isn't bullet proof.

      It depends on what is running on the machine. If file sharing is =
turned off but you have some exploitable service running like say telnet =
server, then yes it's possible to login remotely (or hack in if you use = an
exploit for the service) and gain full control of the machine. After = that you
can do anything you could do if you were sitting at the = machine.=20

      The format of the HD is almost unimportant to the point of not =
mattering.

        If on a Win2K or XP machine file sharing is turned off, even if =
a hacker gets into the network from the internet side can they get on = that
machine and do anything with it?  Same question but assume hard = drive is
formatted FAT 32?
