No, I don't think I have a VPN or any virtual adapters enabled. I am now using Intel(R)PRO/100 S Desktop Adapter, but I still saw the problem when I used a different adapter (Intel 8255x Based Integrated Fast Ethernet). I have two machines that have this problem. I reinstalled Windows on one, and I didn't see the problem any more. Do you know any reference document talking about this bug?
