Some small number of people are reporting PS/2 keyboard or mouse failures in the Windows 2000 newsgroups . The installation goes fine, but after reboot, the keyboard and/or mouse does not respond. The solution taken by those effected is to change to USB versions keyboard / mouse combinations. No common factor noted yet.

The majority of modern PCs use ps/2 style keyboards and mice so its not a general failure. I am running Windows 2000 Professional workstation on just such a configuration.
