I have mine working, WIN 2k dosen't technically support it though BUT, this is how you get it to work.
Go to teh Gaming options control panel, if it dosen't find it, click Add, scroll down the list of available controlers, pick Microsoft Sidewinder(Auto Detect), it should then find your controller and give it it's proper description. The problem is that it should work, it may not, and it may go nuts after a couple of games without a reboot, I know mine runs fine from about 2 hours in NFS/HS, a Game that shouldn't work in 2000 BTW, and then it gets twitchy, sometimes jamming to one side with a high force level. but it worked well in most games. It works nicely in MW3.
