Connect to Windows Server 2016 SMB share from CentOS - session setup failed: NT_STATUS_CONNECTION_RESET

  • 772

I tired to mount a Windows SMB share in Linux using autofs, but I kept getting 'access denied'

I decided to test it using smbclient, but I am just getting 'session setup failed: NT_STATUS_CONNECTION_RESET'.

sudo smbclient //myfileserver/myshare$ -U windows_service_account -W MYDOMAIN

There shouldn't be a firewall and the errors aren't very helpful.

Any idea what to check next?

smbclient

  1. 2016 blocks v1 SMB by default.

    Perhaps enable that on the Windows Server (less secure...not great) or change smbclient to use minimum version 2.

    Just a guess though.....

    Also, wasnt sure how to tell you to change the version in CentOS so here you go:

    Edit smb.conf file, run: $ sudo vi /etc/samba/smb.conf

    Find the [global] section and append the following line: min protocol = SMB2

  2. Removing -W resolved the issue
