No. Perhaps I need to increase log level.

I hope now you have.
One other info. md5sum are identical when coping the file from
a Windoze 2000 system to the same samba box.

No. I'm copy from windows to linux. I'm not mounting any windows share
on linux.

PS: Samba was builded from source on Slackware Linux 9.1
(gcc 3.2.3 glibc 2.3.2) + vanilla kernel 2.4.26
