Unable to access Guest SMB shares

TrueNAS General
1

Hi all,

I’m having difficulties trying to access Guest SMB shares on our TrueNAS. When attempting to access the shares, we’re receiving a prompt for a username + password.

I’ve made sure the ACL for the Share has ‘everyone@’ set to full access, and that the filesystem also has the ‘everyone@’ permission.

I’ve tried restarting the SMB service, the whole NAS, creating new Shares on different Data Sets - all the same issue.

This problem occurs when trying to access the share from any computer (tested windows 10 and 11 machines).

I noticed in the ‘Advanced Options’ of the SMB service, there’s a ‘Guest Account’ field, which is set to ‘nobody’. I attempted creating a new account on TrueNAS with no password, and giving this account full Share and FileSystem permissions, then replacing the ‘nobody’ account with my newly created one, and restarting the SMB service again. However the same issue happens.

The TrueNAS version I’m using is 24.10.2

Has anyone else had this issue? Any ideas or suggestions on how to fix this?

Most modern windows clients do not support this type of guest authentication. You should just create user accounts (much preferable option to degrading your client security).

Ah, thank you for this. Just checked from a Debian machine and can access it fine, so seems to be a Windows issue like you mentioned.

I guess this is solved! Will look into the Windows side of things now :slight_smile:
