this is the difference between win2k and *nix (fBSD on my box):
freeBSD box: dual p166, 128 megs
win2k (formerly NT4 box): dual pII 550e, 256.
fbsd can do everything the NT/2k box could do (except PDCing and maybe they can do that with the right proggy) and on about 200 bucks worth of hw, as opposed to thousands. Also, the sw is free, and you don't have to install some 120 dollar software to get ls and grep.
Also, our 2k is bogged down being our BACKUP external server (granted, it's our PDC, but only on a 12 user net, both comps fileserve, but 2k machine == nfs gateway, so there's a LITTLE more strain on it) and our dual p166 sits there at 20% / 45 megs free all the time (40% / 3-4 megs free while serving a number of X apps).
Both OS's are damned stable, and they are both good. It just depends on what you're doing with it. NO ONE IN HIS RIGHT MIND SHOULD INSTALL LINUX ON A STRICTLY PERSONAL COMPUTER. LINUX IS A POOR MAN'S COPY OF REAL UNIX, an OS designed for servers. Win2k is a very nice internal server/pc os.
Someone prolly already said that, but I don't wanna read all that stuff up there =].
BTW, I might go so far as to say that stability is solely based on ADMIN. Since it's his/her job to buy the hw, set it up, decide which system best fits the application, compile/write modules for the kernel, etc... If he does any of that wrong, and the system crashes, it's still his damned fault.
I pride myself int he stability of my machines, and if my HD goes out, i say to myself... "I shoulda done more research, gotten a better drive" or "gee, maybe i shoulda spent that extra few hundred and gotten raid... sure would be handy now" then i kick my own ass.
Now, should someone be placed in a position where he MUST run some os (either by a need to play games, or by previous sysadmins screwing things up, and everyone's unwillingness to pay for/deal with it's fixing, he can only do so much. I went to a place with a consultant to help him fix a windows server... I was thinking winNT... it was WINDOWS98. What the hell is that? Anyhow... a sysadmin/consultant should know what to choose for his clients.
It is totally impossible to run windows 98 for a month with no probs (not just crashing the OS, i'm talking about 3ds crashes, quake quitting out, net neighborhood ceasing to post net info, losing hardware, unfixable mem leaks... having crazy alert boxes not go away, and positioning them really far down the screen and hoping no one notices). Maybe if you just turn it on and leave it there, it'll be ok when you come back to it.
