	Ok...  I'll step into this one just to start the ball rolling.

	I haven't seen your other messages so you will have to forgive
me if I ask questions which you already answered.

	Samba on what?  Linux?  *BSD?  Solaris?  HP/UX?  AIX?

	If Linux...  What version kernel?  What distribution?  What
version distribution?

	If BSD - Which BSD and which version?

	If Solaris - Sparc or x86, and which version?

	What version Samba?

	Did you build it yourself or did you install it from package?
(.rpm, .deb, .pkg, etc, etc, etc...)

	ALL of these matter.

	All but the most recent version of Linux did not effectively
support files larger that 2 Gig.  Large (64bit offset) files required
both support in the kernel and support in the libraries, so just upgrading
to a 2.4.x kernel would not cut it.  You need a recent distribution where
the 64 bit functions such as lseek64 are supported.

	It's probably NOT a Samba problem, or if it is it's a problem
with Samba recognizing the large file support on the platform you are on.
It's probably support in your underlying OS, or the support libraries, or
the build configuration.  Impossible to tell which without a LOT more
