Samba is not involved here, so 2.0 or 2.2 makes no difference. The problem
you are seeing is that smbfs, a kernel filesystem, does not implement file
locking. The result is that the linux client (dosemu) thinks it gets the
requested lock but the server has not granted that lock.

I also don't know if running programs in dosemu will make the lock
requests reach smbfs or not. If it does not then changing smbfs will not
help.


There are some experimental patches for smbfs, but nothing that is ready
for production use. If you feel comfortable building your own linux
kernels then I can send you the address of the patches. But there is
nothing that says they will work.
