Im trying to move some files off of my laptop(xp home) onto a 2003 server (running AD) over a 100mbut ethernet line, both machines on the same switch. The files are approx 15 megs a piece and total files is around 40gigs. The network transfer will begin, and around 1-2 minutes into the copy, ill get a "Cannot copy FILENAME: The specified network name is no longer available." error on the laptop. The account im accessing the server with has full permissions for the folder im copying to. I tried running a continous ping, while copying the files over, and i got the error again (no hiccup from the continous pinging). I also checked the md5 hashes on the files that were copied over to the server, and they all checked out, so the data is getting across ok.
