After restarting TrueNAS the users cannot connect to their SMB shares

TrueNAS General
1

Hi,

For about few weeks I am struggling with my TruNAS. After I reset the Server the SMB users cannot connect to their shares. If don’t restart the server and I set a new passwords everything works fine.

At first I was working with the Freenas 11.3, after some time I updated it to 11.3 U5. With that version the issue started to appear. I tried to update to Truenas 12.0 Core, which went ok. Eventually I update to Truenas Core 12 U8.1.

Unfortunately the issue still exist.

Can someone help me with that issue?

My Truenas specs are:

  • Intel Pentrium Dual Core E5800,
  • 8GB RAM DDR3,
  • 2 NAS HDD’s configured in “mirrored” mode,
  • 32 GB USB 2.0 flash for booting the OS

Regards,
Sławomir Halota

How are you users connecting? Do you have a user set up just for SMB sharing on TrueNAS Core? What OS are users using to connect, Windows 10, 11? What error messages?

Please provide as many details as possible.

Hello,

The users are connecting from Windows Exploreel, where I chose the option “Map network drive”. They are using Windows 11.

The accounts are setup mainly for SMB, there is also one Epson Multifunctional printer which scans via SMB. One of the accounts is used for it.

i’m not familiar with those old versions, but for sure you can grab some audit from GUI, they can for sure help debugging.

I forgot to mention, when I restarted the server the Windows error with the smb shareel says “wrong user or password”.

I tries to contact Ixsystems for support, but they couldn’t help me because I didn’t have a subscribtion.

according to guides, freenas 11.3 has been released on January 28, 2020, so it should already use NTLMv2 by default.
Have you instead activate the NTLMv1 or used some aux param?
What NTLM version are your client using? Should be Send NTLMv2 response only. Refuse LM & NTLM.
Also to mention, that the problem can be entirely on clients, sometimes is worth to delete credentials from the ms store, and re-add

legit :smile:

When I will be near the server I will check those parametres.

When it comes to credential manager in Windows I only clear the saved passwords for SMB share, but the rest I lef.

Also I need to add that when I restart the server the SMB users doesn’t work with Network scanning. It is set in the Epson multi functional printer which has it’s own OS.

That’s why I think that the issue is on the server side.
