Looks like you didn't really understand Marc's answer.

This depends on settings on the Windows client. On the server side, this is not a question of changing behaviour, it's a question of Samba 4 supporting a new feature, SMBv2.

I suppose that the only thing you can do on the server side is setting max protocol to SMBv1, which is really bad for performance and for security. People have been disabling SMBv1 everywhere.
