NDT finds duplex mismatch?

I ran a network diagnostic tester (NDT) on my connection just to see how my speed ranked and I received the following report: TCP/Web100 Network Diagnostic Tool v5.2.1d click START to begin Checking for Middleboxes . . . . . . . . . . . . . . . . . . Done running 10s outbound test (client to server) . . . . . 440.14Kb/s running 10s inbound test (server to client) . . . . . . 2.10Mb/s Your PC is connected to a Cable/DSL modem Alarm: Duplex mismatch condition exists: Host set to HD and Switch set to FD I am not having any serious problems with sending and receiving data but every now and then I seem to so I'm wondering if I really have a problem? I'm running Windows XP Pro and access the internet over a DSL modem. Any thoughts? thanks ahead of time.

hi dank_64, iam not familiar with that tool you ran, but a single result from some server will only tell you about that route at that time under that server load. results can vary alot. shelf life
