[python-win32] (no subject)

[walou]

Thanks for your quick answer, I've thought a little more about it and
ftp, ssh, and other external methods can't be used. Our servers are
installed by teachers, or other tech assistants and we don't have any
control on the server's accounts. So we have to use a built-in method to
transfert files. XML-RPC should be a good solution.

About the problem about registry modification, we've used a brutal
method. ;-)

user open a session on XP, samba preexec sends the remote registry
function to the NT service which loops 300 times (2/10 seconds
interval). The samba server doesn't wait for the registry to be
modified, continue its process, user gets his registry hive, loop's
still runing and can now modify the registry.

I hope that one day we'll write a dll that gets the "open session" event
and does the process cleanly.
