samba - Mar 2002 - Windows 98 Explorer still can't copy larger files to Samba share

I recently installed 2.2.3a in the hopes of fixing the problem I have when
copying files
from a Windows 98 box to a Samba share running under RHL 7.2.

I can browse the share, read files, and write very small files (under 1KB), but
when trying
to store a larger file into the Samba share, it starts the copy, shows the busy
cursor for
a while, and then pops up a dialog box with a message such as
 Error Copying File
 Cannot create or replace test.txt: The specified network resource or device is
no longer available.

After dismissing this dialog box, I can see that the file was created, but that
no data was stored
for it.  The file name appears in the share with a size of 0 bytes.
Nothing shows up in the log files about this.

I've tried adjusting settings for the create mode (750), and a few other
things,
but nothing seems to fix the problem.  

Is anyone else having this problem, or is there still a problem with my
configuration?
