Yes, it happens if you try run a 16 bit application (e.g. WinZIP
se-archive). Note, that it does *not* happen if I run *the same*
application from NT server. To test is very simple:

  create self-extracting archive e.g. with WinZIP (be shure to mark
  16 bit)

  rename archive to something like 123456789.exe

  try to start it from SAMBA - you get error message "123456789.exe not
  found"

  Now, copy *the same* archive to NT server and run it from there - runs
  perfectly. Note, that WinZIP gets mangled name - something like 
  123456~1.exe

Most probably, there *is* a difference in API calls between 32 and 16 bit
programs, which are not taken into account by SAMBA. Working on WinNT 4.0
I could not force SAMBA (1.9.18alpha11) to mangle names at all - in
spite of *all* mangling parameters set to yes. 

Note, that the same problem applies to directories as well - currently I
am forced to name all directories on SAMBA in 8.3 format, because LFNs
make installations of 16 bit programs fail (the same names on NT work
fine). Not very handy.
