Createing Install routines for client server apps

Hi

I'm not sure this is the right place to ask these questions, but hopefully
some of you have been through somethng similiar.

I am in the process of creating a CD for customers to install my Firebird
based delphi(using IBO and fbclient) application. The target systems/users
will include non technical people installing to standalone PCs, not very
technical network managers/technicians installing to networks and highly
competant network managers installing to networks.

I have been keeping my installation routines simple by using Inno setup to
create a setup.exe that installs my application and then installs firebird
with the silent switch. I was hoping that on a network, that it would be
possible for the network manager to run my installation routine and then
make a shortcut on the user's desktop that would run the client application.
Users would then use my client application (that would be installed on the
server), using the client machine as a terminal. ie nothing being installed
on the network client machines. However, having setup a windows 2000 server
here at home, I am now understanding that this is what people have said
won't work! Sorry for being slow on the uptake, but I am very new to
networks and client server databases, and going up what seems like a huge
learning curve!

So this leaves me wondering where to go now It seems like I have to offer
a 'client only install' as well the existing setup.exe, for networks client
machines. This might as well include my client app as well as a client only
install of firebird (Helen's book has a very clear description of how to do
that). It then seems as if there are 2 ways of achieving this:
1) Using Inno to create a client setup.exe that the network technician will
use by logging onto the client pc and installing it.
and/or
2) Use something like winInstall LE to create a .msi package that the
network manger can then assign to a user if the network supports windows
installer packages.

Am I 'barking up the right tree' or can I no longer see the tree for the
wood?!

Thanks for any comments
