A few things .. First, both speed & duplex are set manualyl at both ends. In fact, I did this more than a year ago as a recommendation to solve this particular problem we're discussing now. In other words, the problem existed before I manually set speed/duplex, and afterwards. Second, the problem doesn't ever sort itself out. If I don't reboot the server, the problem continues indefinitely. Last, here is the output of netstat and ifconfig: http://www.tranceambient.com:8000/public/netstat.output.txt Note: The parts marked with 'x' are indicating my internet IP address, which I am futilely trying to mask. Thanks. -- Adam
