I'm interested in the original posters post regarding improving performance in Windows XP. Only now I'm on Windows 2000 and want to know if there is something equivalent I can do in Windows 2000.

Most of the tweeks for XP aren't needed for Win2k. The only tweek that will likely be super helpful is the game tweek to enable compatability mode:

Aside from that, try to have 2gb RAM (any more than that is a waste, and in reality, anything more than 1gb doesn't really do much), I WOULD SUGGEST defragging your swap drive, then making your swap file minimum size equal to the suggested swap file size, with the max 1.5 times minimum.
