That is a big open ended question that poses a lot of other questions. Am I correct in assuming that you have a domain setup? I am not super familiar with 2008 since I have been focusing on finishing up my 2003 exams (I fell a little behind). The first thing to do is figure out why things are unstable. Don't assume it is the server and workstation OS is old that is lending to instability. If your looking to upgrade just to get current great! 2008 has been out long enough to get out the worst of the issues. So it is simply a matter of picking the versions that best fit your needs. Unless you are running a very simple network Enterprise edition might be best. Don't forget to add in the cost of all of the new licenses, terminal services (if you use it), exchange, sql and anything else you use will need to be upgraded along with it. Remember to that unless your servers were really good then they will probably not have enough horsepower to run 2008 smoothly. Switch to XP if you can win7 if you can't since 2000 pro will be out of support soon enough. It might be time to look into gigabit ethernet if you can afford the cost as well to expand the bandwidth available.
So I would say look for your weak links (hardware, network components, ect) for the quick easy fix. Going to 2008 server and xp or win7 for the workstations would be very costly and would depend on the other parts of the server/domain setup you have.
just some food for thought!!
Get your facts first, then you can distort them as you please.
