[Samba] problem with samba and a dos application

[Stephan von Krawczynski]

Hello all,

I am trying to export a share to several Windows clients, that start some
application in a dos box. The application itself is located on the share. The
first client can start it, the second cannot. It looks like a locking problem,
but experiments with "locking = no" showed no effect. The application in
question is OpenAccessIII (SPI), just in case somebody knows it.
Any hints are welcome.
