Locking issue

[W.J. McEachran]

I know this has come up before....but..
I've got a locking issue I can't get over.

Situation:
---------
Unix writes a file to the /tmp directory
MS-DOS (WFW 3.11) copys over the file (copy d:\file.txt ), locking it, and 
  not releasing the lock.
If Unix subsequently changes the file a re-issuing of the MS-DOS 'copy'  
  command will appear to work ... but the MS-DOS file is _unchanged_.
If MS-DOS deletes the file and subsequently re-isses the MS-DOS 'copy' command
  the OLD version of the file re-appears.

IE)
UNIX DOES                                
---------                                
copy /u1/tmp/input.prc /tmp/input.prc 
cd /tmp
l /tmp/input.prc

The relevant parts of smb.conf are:

[global]
  allow hosts = allowed IP range etc.
  guest account = nouser
  comment = SCO OpenServer 3.0
  workgroup = office
  public = yes
  guest ok = yes

  security = user
  wins support = yes
  domain logons = yes
  logon script = %U.bat

  socket options = TCP_NODELAY
  preserve case = yes
  short preserve case = yes
  share modes = yes
  domain master = yes
  local master = yes
  preferred master = yes
  os level = 65
  writable = true
  lpq command = /usr/bin/lpstat -o %p
  printing = bsd
  printcap name = /usr/local/samba/lib/printcap
  load printers = yes
  print command = lp -d%p -oraw -s %s; rm %s
  lprm command = /usr/bin/cancel %p-%j
;  locking = yes            << I've turned this on & off -- no change 
;  op_locks = true          << ibid (also fake oplocks)


[tmp]
; map to D:
; We're NOT preserving case here (everything goes lowercase) as it breaks
; several shell scripts relating to payroll data IMPORT.
  comment = temporary files
  path = /tmp
  read only = no
  public = yes
  create mode = 0644
  preserve case = no
  short preserve case = no
 ; fake oplocks = yes       << also tried 'locking =no' and 'op_locks = false'


Thank in advance for any insights offered.
