They may not have much choice. Once you install a 2003 server that provides
authentication, such as AD, you need a Microsoft CAL for each person
accessing it. If all of your employees, or a majority of them anyway, will
be using the new software, then they each need a Server2003 CAL.

After that it's about $600 each in licensing to take of the remaining
servers to 2003. Unless you need to buy new hardware, and if you're still
running NT 4, you may need to.

Your finance department should understand risk and running NT nowadays is
very risky since there aren't any patches available for it.
