If you have a choice, W2000 is a very stable platform (if one can call Windows stable at all...).. .There is one downturn, people with games and some special software especially programmed for the DOS environment may face a problem as not all run under W2000. . .But then again, there are plenty of upgrades available and the dinosaur programs have been replaced with better ones already.. .W2000 is basically from an users point of view very very similar to 98, in detail you can however do much more with it and I have a server running on W2000 on a 24/7 basis with absolutely no problems at all.
