[Samba] v3.2.0 and MS-DOS: Directories must be upper-case??

I have an MS-DOS client (Win98SE boot disk) connecting to a Samba v3.2.0
server which is a member of an AD domain (WinNT 5.0/2000 DCs).  If it
tries to create a file in a directory, it will fail if the path is not
all-upper-case.  For instance:  J:\Bk-Full\DJohnson\S1565\  will fail but
J:\BK-FULL\DJOHNSON\S1565\ will succeed.

When it 'fails' the desired file IS created, but contains nothing (0
bytes) and the DOS computer returns an error.  If I try the simple command
  ver > test.txt
the message will be "File creation error."  Attempts to delete the file
from DOS give "Sharing violation reading device CON; Abort, Retry, Ignore,
Fail".

Directory creation/deletion works regardless of path-case.  I have tried
setting 'case sensitive = no' just as a guess, it didn't help.

Below I've pasted most of my smb.conf (global + the share in question).
Note that the DOS client actually logs in on the domain, and is given
access in smb.conf and filesystem ACLs as "DOMAIN+BackMeUp" (obviously not
case-sensitive).
