Enterprise application usually refers to the following
characteristics:

1) Designed to Scale (typically means you can just throw
more hardware at it and see an improvement in performance)
2) Interface, Business Logic, Data all seperable and even
multiple layers of business logic can be run in different
application domains.
3) Durable, meaning that the process has built in
mechanisms to recover from disaster...

I know this is very vague, but a minimally deployed
application running on one machine can be an "Enterprise"
level app if it meets the above requirements (Remember
just because you have it in one machine doesn't mean that
you can't split it out to many app domains, an application
domain can be local or in seperate physical machines).

..NET Enterprise from Wrox Press will give you a good taste
of the true power of the .NET framework.

..... natural or otherwise, i.e. hardware failure, media failure, fire
flood, etc, etc. Something many companies never took seriously until
9/11.

Excellent point, by the way.
