[Samba] Legacy samba 3.x connecting to server 2022

[Greg Dickie]

Hey Rowland,

  Thanks for the reply. It was indeed SMB1 that was missing. It had been
installed but not rebooted so of course was not working. I know we have a
mix of versions but some 3.6 which should be able to do SMB2 so I'll
definitely try that out. It was just kind of a surprise that they updated.
Of course they also had issues with old Windows 2003 servers that also need
SMB1.

Appreciate the help,
thanks,
Greg
