Well, I hope you're around for a lot of question/answer/fixing.

This is not black box technology that just sits in the corner of some closet.

NT 4 (people to call and ask help = 10's of thousands)
2000 AD (people to call and ask help = 1000's )
2003 AD (people to call and ask help = 100's )
(Your mileage may vary)

With so few employees and given that I'm sure there NT 4 is paid for by now. Why the "need" (fear of no support from MS? ohhh... I'm scared) to upgrade? 2003 is not free, and neither is new hardware if required)

Think most people would agree with the upgrade, but I think I would at least TRY an all new setup myself with such a small user/server group. However, you may not have the time/hardware/etc... to do so in which case it is probably better to do an in-place update.
