Can win2000 support usb cdrom autorun function?   

I have a Usb harddisk box, and I install a CDROM in it, when I insert a CD
with autorun.inf and related executable file and icon,the executable file
can be executed autometically in WinXP. But in Win2000, the CDROM can be
accessd, but the executable file can't be executedautometically. Why?

Please tell me the reason, my dear friend, thank you very much.
