Bug # “Windows 7 Pro machines trust relationship fails” : Bugs : samba package : Ubuntu
we have a server (Debian) running Samba version serving about twenty workstations running Windows 7. to log in, with the message "The trust relationship between this workstation and the primary domain failed.". Nov 22, Logon fails with "The trust relationship between this workstation and the primary I heard you saying "Disjoin and rejoin the machine to the domain" You may ask how that can happen if Windows 7 doesn't change the.

"The trust relationship between this workstation and the primary domain failed." – Reference Point
For the SC to be successfully established, the computer account password stored in Active Directory and the member's password known as LSA secret and stored in the member have to be in sync. The member has to change its password every 30 days by default.
Maximum machine account password age" using Local computer policies or domain GPOs. If you increase this interval significantly, or set it to 0 so that the computers no longer change their passwords, an attacker will have more time to undertake a brute force attack to guess the password of one or more computer accounts.
Which breaks the secure channel immediately. Let me give you 3 examples for clarity sake: Same situation but now Joe closes his laptop and leaves it on his desk. When he returns notices his laptop has been stolen The computer password gets reset later on the same day and life goes on.
"The trust relationship between this workstation and the primary domain failed."
Wisely the IT department has upgraded all laptops to Windows 8. So when Joe returns from leave experiences no problems logging on to the domain because his computer only changes its password if it can contact a DC. By the way if you read my previous blog, mind the Windows XP support lifecycle note.
Recently I came across an issue that has been puzzling System Admins minds for some time. The security database on the server does not have a computer account for this workstation trust relationship What is the cause for The trust relationship between this workstation and the primary domain failed error?
When you connect the computer to Active Directory domain it sets a password like for AD users.
Trust at this level is provided by the fact that operation is performed by Domain administrator or another user with the same rights. Each time when domain computer login to the domain, it establish a secure channel with a domain controller and send credentials. In that case, trust is established between the workstation and domain and further interaction occurs according to administrator-defined security policies.*EASY FIX* The trust relationship between this workstation and the primary domain failed
The computer account password is valid for 30 days by default and then automatically changes. It is important to understand that the change of password initiated by computer is defined by Domain policies. This is similar to the changing user password process. You can configure maximum account password age for domain computers using GPO Domain member: Maximum machine account password age, which is located in the following GPO editor branch: You can specify number of days between 0 and by default it is 30 days.
For a single machine, you can configure the machine account password policy through the registry. To do this, run regedit. Edit the value of the MaximumPasswordAge parameter, in which you can specify the maximum period of validity of the computer password in the domain in days. Other option is to completely disable sending a request for computer password updates, by changing the value of the DisablePasswordChange parameter to 1.
The Active Directory domain stores the current computer password, as well as the previous one just in case.
Fix Trust relationship failed issue without domain rejoining
If the password was changed twice, the computer that is using old password will not be able to authenticate in the domain and establish a secure connection. If the password has expired, computer changes it automatically when login on the domain. Therefore, even if you did not Power on your computer for a few months, trust relationship between computer and domain still be remaining and the password will be changed at first registration in the domain.
Trust relationship failed if computer tries to authenticate on domain with an invalid password. Typically, this occurs after reinstalling the OS, then the system state was restore from an image backup or snapshot of the Virtual machine, or it was just turned off for a long time. In this case, the current value of the password on the local computer and the password in the domain will be different. The most obvious classic way to restore trust relationship is: Reset local Admin password Move computer from Domain to workgroup Reboot Reset Computer account in the domain using ADUC console Rejoin computer to the domain Reboot again This method is the easiest, but not the fastest and most convenient way and requires multiple reboots.
