Dan Pyle one of the gurus at Microsoft is producing a small executable file to be used in place of the SMB1 protocol. I'm sure he's been pestered by other guys like me who need to keep very old Mazak or similar machines running on a network to allow file transfer and job monitoring. He announced this executable in Dec 2023 but as yet nothing is available.
Hopefully something will come up soon as we're living on the wire here with our machines.
