[Samba] 2 GB Limit when writing to smbfs filesystems

I'm running RedHat 8.0 with samba-2.2.7-5.8.0 (installed from RedHat

When I use cpio to write a backup (> 2GB) to a smbfs filesystem, I get the
error: File size limit exceeded
I get the same error when I linux copy (cp) a file (> 2GB) from a Linux ext3
filesystem to the smbfs filesystem.
The smbfs filesystem is mounted from a Windows 2000 Professional

After experiencing the problem, I installed an NFS client on the Windows
2000 Professional workstation (for testing purposes).  Everything works with
NFS, but I want to make it work with samba.

I DO NOT get an error when:
MS copy from NTFS to samba share (i.e.  copy c:\bigfile
MS copy from samba share to NTFS (i.e.  copy \\linuxsvr\smbshr\bigfile
Linux copy from ext3 to ext3 (i.e. cp -p /home/bigfile1 /home/bigfile2)
Linux copy from NFS to ext3 (i.e.  cp -p /nfs/bigfile /home/bigfile)
Linux copy from ext3 to NFS (i.e.  cp -p /home/bigfile to /nfs/bigfile)

I ONLY get the error when linux is trying to copy (cp) or write (cpio, tar,
dd) to a mounted samba filesystem.
(i.e. mount -t smb //win2k-ws/share /mnt)

Do I need to install something for linux to treat the mounted share as a
CIFS filesystem?
