I set up a LAN as the test Environment, including one FTP server and one client and no other net conmmunication resources(So I think it should be a "clean" net env.).However, when I download a file from the server, there are still lots of packets which info are "TCP previous segment lost". So:   1. What's the reason about this? 2. I also find an interesing phenomenon: the "Tcp previous segment lost" packet appears about every 100ms (Both the server and client are Windows OS). Is it just a coincidence or it's kindof necessary thing that conforms to some net protocals and regulars?   Thanks! Invite your mail contacts to join your friends list with Windows Live Spaces.
