Say I have a 670 MB file and I want to copy it over the network using SMB (FROM a Windows machine, TO a Linux machine), and both Windows Explorer and Teracopy only get through like 10-50 MB and then freeze up and stop copying. And furthermore say that I can copy gobs of other files to the same server at the same time (like while the 670 MB file is sitting there stalled) quickly and without problems.

Any ideas wtf could be happening here?
