samba - Oct 2003 - Samba 2.2.7a and Word 2000 = Corrupted (?) files

I have a Samba 2.2.7a PDC (with an OpenLDAP backend) that seems to be giving
me trouble.  Here's the scoop:

I have Windows 2000 Pro clients running Word 2000.  Over the past several
days, a lot of them have had trouble with their documents - most of the time
during a save.

The most critical of these failures presents the following error message
when saving:

"Word has lost data due to a bad network connection or missing floppy.
Documents relying on this data are going to be saved and then closed."

The only option on this dialog is to select "OK" and word commence to
save a
"rescue document".  This takes a VERY long time - in excess of 10
minutes.
Immediately following that process Word presents us with another error
message:

"There is an unrecoverable disk error file <File Name of Current
Document>.
The disk you're working on has a media problem that prevents Word from using
it.  Try the following:

Try Formatting another disk.
Save the document to another disk."

Then Word goes and saves a files called Rescued Document <#>.txt in the
user's My Documents folder.  Looking at this file is worthless as it appears
to be hex-code or something.  This basically ends up with the user loosing
work - a total of about 9 hours over the past three days in this most
extreme case.

I have scoured the mailing lists, Google'd for possibilities but have been
unable to come up with any solution.  I'm hoping someone here has run into
this and may be able to point me in the right direction.

I have included the smb.conf file from the server in question below - in
case it helps.  The problem files are stored in home, admin and projects
shares.

# This is the main Samba configuration file for Stargazer - NEI's Primary
# Domain Controller and Lexington office File Server.
#
# This configuration file is only to be used for an LDAP enabled server that
# will be acting as a PDC.  Modifications will be required for member
servers
# and machine that will act as "BDCs".
#
# Any line which starts with a ; (semi-colon) or a # (hash) 
# is a comment and is ignored. In this file we have used a #
# for commentary and a ; for parts of the config file that are
# either not enabled yet, or temporarily disabled
#
# NOTE: Whenever you modify this file you should run the command
"testparm"
# to check that you have not made any basic syntactic errors.
