I maintain a small business with a ubuntu 14.04 server running samba 4.3.9-Ubuntu. Everything worked fine with Windows 7, after upgrade to Windows 10 only those can log in to a PC who already logged in once before the upgrade.
For everyone else all I get in the error logs is
NT_STATUS_CONNECTION_RESET
and on the client side it says, that no login servers are available.
I already tried disabling SMB2/3 but this does not help.
I am really confused that some users work (those who already have their profile synced to the pc) and the others don't.
