This happens upon a Tree Connect? A tcon without a session setup before?

It sounds a bit strange that a Windows machine will set up a fresh tcp
connection and *not* do a normal smb session setup including negprot, sesssetup
and tcon in that order.

What we would need is a complete debug level 10 log.smbd and a capture of the
traffic between the windows machine and the Samba machine. The complete traffic
might be important, as something in the way the former connection was turned
down (or not properly turned down) might trigger that behaviour.
