That's interesting, and it's always good to collect more information.

But it's not surprising, as there is a lot of variety in NICs out there, and a hack that affects some nics like will not affect others. We do have records in some other threads on this forum of Desktop users who have been affected. And the most significant clue to this problem still seems to be my own experience that Knoppix booted from CD worked just fine on the network under XP for several weeks, until I installed the "security updates". Now the same CD(s) fail to bring up a network connection.
