How To Fix Domain Trust Issues in Active Directory -- mephistolessiveur.info
Just a quick powertip here whenever you get this message on a client's computer : "The trust relationship between this workstation and the. trust relationship between this workstation and the primary domain failed Another option they will give is to delete the computer object and. Delete computer account from the active directory then try re-adding. Dejoining a machine from the domain does not remove the computer.
The reason why this problem happens is because of a "password mismatch.
DON’T REJOIN TO FIX: The trust relationship between this workstation and the primary domain failed
However, in Active Directory environments each computer account also has an internal password. If the copy of the computer account password that is stored within the member server gets out of sync with the password copy that is stored on the domain controller then the trust relationship will be broken as a result.
So how can you fix this error? Unfortunately, the simplest fix isn't always the best option.
The easy fix is to blow away the computer account within the Active Directory Users and Computers console and then rejoin the computer to the domain. Doing so reestablishes the broken-trust relationship. This approach works really well for workstations, but it can do more harm than good if you try it on a member server. The reason for this has to do with the way that some applications use the Active Directory.
Take Exchange Server, for example. Exchange Server stores messages in a mailbox database residing on a mailbox server. However, this is the only significant data that is stored locally on Exchange Server.
All of the Exchange Server configuration data is stored within the Active Directory.
In fact, it is possible to completely rebuild a failed Exchange Server from scratch aside from the mailbox database simply by making use of the configuration data that is stored in the Active Directory. The reason why I mention this particular example is that the Exchange Server configuration data is stored within the computer object for that server.
Fix Trust relationship failed issue without domain rejoining
So with that in mind, imagine that a trust relationship was accidentally broken and you decided to fix the problem by deleting the Exchange Server's computer account and rejoining the computer to the domain. By doing so, you would lose all of the configuration information for that server.
Worse yet, there would still be orphaned references to the computer account scattered elsewhere in the Active Directory you can see these references by using the ADSIEdit tool. In other words, getting rid of a computer account can cause some pretty serious problems for your applications.
A better approach is to simply reset the computer account. Run this command from PowerShell: The underlying problem when you see this error is that the machine you are trying to access can no longer communicate securely with the Active Directory domain to which it is joined.
When you try to access this machine using a domain account, it fails to verify the Kerberos ticket you receive from Active Directory against the private secret that it stores locally.
Error: The trust relationship between this workstation and the primary domain failed
I think you can also come across this error if for some reason the system time on the machine is out of sync with the system time on the domain controller. 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.
