TrueNAS SMB Share not working on Win11 but on MacOS

TrueNAS General
1

Hello all,

This is pulling my hair out. I recently moved and setup my TrueNAS Core rig on my Unifi UDM with an SFP for 10gbe.

The macbook i have can open the SMB share no problem and I can access the data over wifi. The two windows desktops on one Wifi one on Ethernet give me an “the folder you entered does not appear to be valid”

I can login into my TrueNAS from the local IP on any computer… I have googled the issue and done various things with the windows registry, I have turned netbios id on, made sure the workgroup is correct, etc Nothing seems to work… I have ACL permissions with a non-root user I created setup, that’s been assigned to the the filesystem.

Any help would be greatly appreciated

Do you have any SMB auth log entries correlating with the auth attempts by Windows?

midclt call smb.status AUTH_LOG | jq

I just tired again on the windows computer here’s what I get

And on the windows computer I get this error

You’ve enabled guest access on the share and windows security settings are rejecting it. The general rule of thumb with modern OSes is to not use guest access. It’s not that difficult to create a user account in the GUI.

Create a user account, disable guest access to the share, and then go about your business. :slight_smile:

You can see I was sharing “Vault” before but I created a new share sharing the filesystem up and I see the folder has a new folder name? And that was the cause of my problems…
