File sharing problem with NT

[Steve Litt]

Next step is to have a guaranteed symptom reproduction of the simplest
possible nature. See if that one huge file, by itself, always produces the
symptom. Once you have a directory of files producing the symptom, mark all
files read only so you can run the test over and over. I'd look at three
things:

1. tcpdump (using Samba.Org's version)
2. Log files
3. Exploit differences between successful and unsuccessful transfers.
