smbclient getting NT_STATUS_LOGON_FAILURE connecting to Windows box

rated 0 times [ 40] [ 0] / answers: 1 / hits: 334611 / 2 Years ago, fri, august 12, 2022, 9:38:57

I'm running smbclient on Ubuntu, trying to connect to a Windows box, and I'm getting "session setup failed: NT_STATUS_LOGON_FAILURE".

I've verifed that I can ping the box and telnet to ports 139/445, so I'm pretty sure that it's not a firewall issue. And my client says that they can connect to this Windows box from another Windows box with the userid/password combination without issue. Also, this box can connect via smbclient to other Windows boxes that this client has.

Any other ideas for why this isn't working?

Have you checked your smb.conf?

Make sure your workgroup and security settings are properly set. If you are working with a a computer as part of a domain, authentication requests are first passed through your domain controller, so make sure you have something similiar to:

security = domain

workgroup = WORKGROUP

You can also use the -W option to specify the workgroup, and add DOMAIN/ before your username to specify the domain:

$smbclient -L myhost -U DOMAIN/user -W workgroup

Hope this helps!
