samba - Sep 2001 - "Unexpected network error" copying large files NT->Linux?

Folks --

I've read the FAQ at samba.org/samba/docs/FAQ, I've
searched the mailing list archives for "unexpected
network error", I've searched Google for "samba
unexpected network error", and been unable to find
anything.  If there's another source of information
that I should check, I'd greatly appreciate a pointer.

I'm trying to copy files to Samba shares on a Red Hat
Linux 7.0 box from a WinNT 4.0/sp6a box.  If I drag-n-
drop files larger than 1,000,000 bytes from the WinNT
hard drive to one of the Samba shares, I receive the
error "Cannot copy <file>.  An unexpected network
error occurred."

I have updated the Linux box to samba-2.2.1a-20010711
using samba-2.2.1a-20010711rh70.i386.rpm from
ftp://ftp.samba.org/pub/samba/Binary_Packages/redhat/RPMS/7.0/.

Before the update, I was using the latest Red Hat-
approved RPMs, which are v2.0.10.  With this version
of Samba running, the error message I saw said something
like "Unable to copy <file>.  End of file reached."

I have some users who need to back up gigabyte-size
tar files, and this bug is preventing them from doing
so.  I'd really appreciate any advice anyone can offer.

Thanks in advance for your time ....

Hi Brian,

this seems to be a bug in windows explorer. Try to copy the files in a 
command window. 

Ciao Oliver

Thanks for the input; unfortunately, the copy fails from the command
prompt, also.  I forgot to mention in my original post that I had tried
what you suggested.  Just to be sure, I tried again this morning.  Here's
what happened:

  D:\tmp>net use y: \\yoyodyne\yoyodyne
  The command completed successfully.


  D:\tmp>copy 090000000.dat y:\data1\kasper
          1 file(s) copied.

  D:\tmp>copy 100000000.dat y:\data1\kasper
          1 file(s) copied.

  D:\tmp>copy 110000000.dat y:\data1\kasper
  An unexpected network error occurred.
          0 file(s) copied.

  D:\tmp>

I'm really mystified by this, as the failure seems to occur only
if the file size is greater than 100 megabytes in the strict sense,
i.e. greater than 100 * (1024*1024) bytes.
