Thanks for reaching out, I also suspected there's no alternate SMB client...
We tried both the GUI, to be as close as possible to what users would
do, and a Powershell script. Both behave the same.
For the sake of it, I just tried to use the Linux SMB client within
WSL2: but Windows does not support mounting CIFS that way, only via
their own native client!

This might be possible (though some early tests I did with cygwin
weren't that promising), but ultimately our users just use the GUI, so
that's the concern: we wouldn't be in a position to recommend users NOT
to use the File Explorer in their daily work.
Anyone knowing what happened at the time within samba-technical (if it
can be disclosed)?
