You may be learning an old lesson about clean install versus upgrading the OS. This is an old lesson.
There is also some other issue here. I didn't see any mention of service packs and drivers. These are not automatic.
New upgrade from win98 to win2k comes with problems
MS lists 42 critical updates, 7 win2k updates, and 3 driver updates. NONE of them can be installed. Even, when I tried installing only one at a time, and even after disabling zone alarm, every download attempt fails.
Followup thought. Can I retrieve those updates from my other computer?? Thank you. Chuck
