Well, yes, you have an extract of the log.smb in debug level 10 in my
original email (only the lines saying errors :-)
But I'll be glad to provide you privately the full 200 KB log,
please let me know via email directly.

Yup, done that too (check out my second email today, explaining the
problem is independant of WAN/LAN but instead depends on NTFS :-)

Can't be related to the NIC card, as I've reproduced the problem on
 - HP laptop with NT4 SP4 and 3Com Etherlink II PCMCIA 3c589d
 - HP desktop with Intel 10/100 Ethernet card, NT4 SP4
 - noname desktop PC, with 3Com 3c905 PCI card, NT4 SP3 only

Uh... no I'm using absolute standard gcc version 2.8.1 (installed
correctly with all fixincludes, etc) with just running "./configure" in
samba and not changing anything in the generated autoconf'ed Makefile &
config.h.

Yes, I know the song since I've been using SunOS for years
since version 4.1.2, so I'm pretty used to classic Sun tricks...

/usr/ucb and /usr/ucblib are way out of reach of anything I use,
guaranteed. Here's a proof:

% uname -a
SunOS 5.6 Generic_105181-10 sun4u sparc SUNW,Ultra-1
% ldd smbd
        libsec.so.1 =>   /usr/lib/libsec.so.1
        libsocket.so.1 =>        /usr/lib/libsocket.so.1
        libnsl.so.1 =>   /usr/lib/libnsl.so.1
        libc.so.1 =>     /usr/lib/libc.so.1
        libdl.so.1 =>    /usr/lib/libdl.so.1
        libmp.so.2 =>    /usr/lib/libmp.so.2

It's also not in my LD_LIBRARY_PATH, and I didn't specify
any LD_RUN_PATH or changed anything in the Samba "./configure"
process.

LD_LIBRARY_PATH=/usr/local/lib:/usr/lib:/usr/dt/lib:/usr/openwin/lib

Hope this helps,
Cheers,
