If there was a power failure or someone shutdown the server just by
pressing the OFF switch. A UPS will help in the first scenario, if the
power failure is transmitted to the computer for it to shutdown. As for
the second scenario, a UPS will not help, because it's a user
intervention. Also, there is a third scenario given the fact that you
mentioned it's running on Win98, you get the infamous blue screen of death
and the only way to get out of it is by rebooting and even pressing
CTRL-ALT-DELETE doesn't always guaranty a safe shutdown for IB.

NTFS does help a lot, since it keeps a journal of the changes to a file for
each clusters written to the HD. And, in the event of an abnormal
shutdown, the files listed in the journal are verified to make sure that
these files are alright, and would make the necessary adjustments to the
file(s). In Windows 9x, you would be asked to run a ScanDisk because of an
abnormal shutdown. As you can see, NTFS only exists on Windows NT
platforms(this includes Windows 2000 and XP). Also, if you can run this
application and IB4 on Windows NT/2000/XP, this would garanty greater
stability in comparison to Win9x.

The hosts file is enough.
