[SOLVED] 0xc000018d STATUS_TRUSTED_RELATIONSHIP_FAILURE

[chris.holmes]

Description:
Zentyal 6.1.6 - Ubuntu 18.04.6 LTS
Modules - Network, Firewall, DNS, Logs, NTP, Domain Controller and File Sharing

System is apt-get updated and apt-get upgraded

Production Level Domain Controller only. 75 user license. 73 user accounts.

Running in a VM on an Unraid server that is not part of the domain.
Windows 10 computers joined to domain.
Other Unraid servers joined to domain as file servers.

No ebox packages.
Domain Controller is rebooted weekly and has been running flawlessly for over 2 years.

Hypothesis
Domain based issues with computer to computer authentication.

Specifics:
- Mounting a Windows Share <REMOTE COMPUTER> from a Slackware Linux based (Unraid) <SERVER> no longer works.
- Has been working for close to 2 years until now.

SYSLOG from Unraid Server
<SERVER> kernel: CIFS: Attempting to mount \\<REMOTE COMPUTER>\ServerData
<SERVER> kernel: CIFS: Status code returned 0xc000018d STATUS_TRUSTED_RELATIONSHIP_FAILURE
<SERVER> kernel: CIFS: VFS: \\<REMOTE COMPUTER> Send error in SessSetup = -5
<SERVER> kernel: CIFS: VFS: cifs_mount failed w/return code = -5
<SERVER> unassigned.devices: SMB 3.1.1 mount failed: 'mount error(5): Input/output error

The mounting script goes through SMB 3.0, 2.0 and 1.0 with the same error.

Lookup up this error:
0xc000018d STATUS_TRUSTED_RELATIONSHIP_FAILURE
Comes up with this description.
The logon request failed because the trust relationship between this workstation and the primary domain failed.

Troubleshooting
Removing a couple of computers/servers from the domain and rejoining it doesn't fix this.
The same <REMOTE COMPUTER> (Windows 10) can connect to the Slackware Linux (Unraid) SMB share with no issues.
Two other Unraid servers with different versions of Unraid have the same issue.
Trying to manually make the connection from the command line generate the same error.

Non specific error code issues that might be related.
- Windows Remote Assistance stopped working unless initiated by end user.
   - Been all through the Firewall issues.
   - Remote Desktop does work.
- USB shared printer are acting like they are only capable of one way communication.
   - Adding a shared USB printer works fine.
   - Label printers that don't require bi-directional communication work.
   - Been through all the Firewall is not the issues.

Things I've Done:
- do-release-upgrade caused a major issue. Failed to enable the MySQL service during upgrade. Failed. Revereted VM to previous state.
- Posted this in the Unraid forms as well.
- Looking for info on how to upgrade Zentyal to 6.2 or beyond and/or which order to upgrade the Ubuntu LTS Release.
- Creating a test envionment for this VM tomorrow.

Please request any info you may need to help solve this. Thank you.

Win 10 update (KB5028166) - uninstall and re-apply - Fixed all my issues

Note: uninstalling the update then rebooting the system triggered installing the update before the login screen.
FALSE This did not happen. The update was removed and stayed removed, but it looks like it will re-install on the next run of Windows Update.

This has to do with a SAMBA bug. https://forum.zentyal.org/index.php/topic,35598.0.html

Fixed the following issues I was having.
- Unraid mounting an SMB share on a Window 10 Workstation
- Remote Assistance now works when initiated remotely
- Shared bi-directional USB laser printer now works from remote workstations

The Actual Samba Bug - https://bugzilla.samba.org/show_bug.cgi?id=15418

SOLVED-ISH - There is no fix for Samba for Ubuntu 18.04.6 yet. Don't reapply KB5028166 until there is.

SOLVED Patch for 18.04 LTS Bionic - https://launchpad.net/~ahasenack/+archive/ubuntu/samba-kb5028166/

If I were to install your patch, the official updates continue once it reached or exceeded the version of your patch? This bug is affecting me as well
