I did a little more checking on this. there is a known issue with XP clients
and Catalyst 5000 switches with EARL 1 and certain software revisions. I may
be misunderstanding this completely, but it is an issue with the interaction
of the Cat 5K and XP when 802.1x port authentication is enabled. that got me
to reading on 802.1x authentication. interesting.
