Trust Relationship between PC and Domain broken\failed after System Restore
Backup restored to new server loses trust relationship. I tested our Veeam backup by restoring a windows server on to it. password refresh is automatic process that happens between computer and domain controller. Repair a computer's corrupted domain trust relationship with The system failed to register host (A or AAAA) resource records (RRs) for. Error: The trust relationship between this workstation and the Machine was restored to a system restore point or to a snapshot that is old.
In what case we can get this error? For example, when user is trying to login to workstation or server with domain account credential and after entering the username and its password a window appears with an error message: The trust relationship between this workstation and the primary domain failed Or the error may be like this: 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?
Error: The trust relationship between this workstation and the primary domain failed
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.
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. 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.
Fix Trust relationship failed issue without domain rejoining – TheITBros
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. This solution also fixes that problem.
The standard fix This problem can be caused by various circumstances, but I most commonly run into it when I reset a virtual machine to a system snapshot that I made months or even years before. When the machine is reset, it is missing all of the automatic password changes that it executed against the domain controller during the intervening months. The password changes are required to maintain the security integrity of the domain. Support blogs and Microsoft will generally tell you to rejoin the domain to restore the trust relationship.
Another option they will give is to delete the computer object and recreate it without a password and rejoin. Microsoft support article on the topic: Recently, when I ran into this problem, the virtual machine that reset was an enterprise certificate authority joined to my test domain. Well, guess what, Microsoft will not allow you to rename or unjoin a computer that is a certificate authority—the button in the computer property page is greyed out.
Powershell v3 shipped with a cmdlet for resetting computer passwords. For those with Powershell skills, this is a much better option. Powershell v3 ships with the latest version of Windows and can be downloaded from Microsoft: You can fix this by opening Powershell with administrative rights and running Update-Help.
You can use the Get-Credential cmdlet for a secure way to generate a PSCredential, which can be stored in a variable and used in a script. The Server parameter is the domain controller to use when setting the machine account password. A better fix Just change your computer password using netdom. You need to be able to get onto the machine. I hope you remember the password. Another option is to unplug the machine from the network and log in with domain user. You will be able to do disconnected authentication, but in the case of a reset machine, remember that you may have to use an old password.
You need to make sure you have netdom.
