DOS filenames mangled - HELP please

[R.J. 'Red' Clanton, P.E.]

This isn't romantic but it is needed.  Please Help.
It is fast and stable BUT when using an old DOS program we found
from a Win98E2 machine in a DOS window the command DIR :
     Volume in drive R is R
     Directory of R:\AA\SUNLAKE\Crd
    .              <DIR>        07-20-00 11:06a .
    ..             <DIR>        07-20-00 11:02a ..
    SL99-~#5 CRD         1,024  03-09-99 11:03a SL99-1.CRD
    SL99-~W8 IDX         2,048  03-09-99 11:03a SL99-1.IDX
             2 file(s)          3,072 bytes
             2 dir(s)        7,615.00 MB free
The old DOS program needs the short name.

We are running Red Hat 6.2 installed from the box (Samba 2.0.6)
It is important that all W98 Autocad workstations have full
access and that the file attributes are retained for backup.
I copied the R: directory using the Xcopy command.
Attached is the results of the testparm command.
 
Here is the  smb.conf  file:
