You know something, This is not a WPA issue to start with you're not going
even finishing authentication to start with.

Alright, are you getting any specific event on the Radius server?

We can take this one offline, is there a way to directly get in touch with
you? We can post the remedy once we do additional investigation

For your question below, PEAP is supported on Win2k and should work
flawlessly. It's been tried, tested, and deployed by a lot of people
