Nowt wrong with 2000
My CCTV PC ran XP out-of-the-box, right up to the point where it asked my to accept the EULA. Eject, insert Win2K CD, reboot, rebuild, result!
All PCs at home run 2000. Funnily enough all PCs at home can access each other, no problem whatsoever (whereas my mate with 2 XP laptops and an XP PC can share sod all, I even had to put a network card in his printer). They fucked around with too many things on XP (networking especially) that did NOT need fucking about with. With Vista, they've just fucked about with even more.

The XP networking would depend very much on
running the professional version as opposed to the home version. Networking was pretty much disabled on the home version ( by design ).

I was never a fan of 2000. Initially came with too many comaptibility problems due to a lack of drivers. It was only a stopgap until XP was released and mainly was a cover up for the utter failure that was ME. 2000 server was usable but XP pro rendered it obsolete.
I'm not a fan of any OS that is no longer supported.
