I thought that something like that might be the problem, but I can
connect from a win10 machine to a standalone Samba 4.4.5 server, which
has these as the defaults:

	server max protocol = SMB3
	server min protocol = LANMAN1

So, as Windows PE 10 is probably a subset of Windows 10, it should
work. It is definitely worth trying, but if it doesn't work, then it
could be a bug, but in Windows PE 10 not Samba.

What got me thinking along these lines was reviewing Windows PE & PXE

PXE uses common protocols such DHCP & TFTP as  to boot a "blank"
machine
to a network share.

https://en.wikipedia.org/wiki/Preboot_Execution_Environment

In essence, the client loads a network driver that finds a network share 
through DHCP or TFTP, and from that share, it downloads whatever files 
are necessary to "install" an operating system (Solaris used to do
this)

Windows PE is a subset of the full Windows installation, so yes, it 
essentially boots a slimmed down version that acts much like a command 
line environment from which the entire operating system can install.

https://en.wikipedia.org/wiki/Windows_Preinstallation_Environment

It's a nice method of being able to install new clients with a prebuilt 
environment to a new machine.

It's more-or-less hands-off while the installation takes place. We used 
to do that with Windows NT 4.0

And, as I said, we used to do something similar installing a brand new 
"blank" Sun machine (install from network)

I have a USB drive that "boots" Windows 7 PE  It allows me to install 
new machines or to troubleshoot existing.  You use "net connect" to 
connect to a network share and download whatever tools you need from there.

Can you get a debug level 10 log from Samba, plus a wireshark
trace of this operation failing please ?
