Hi All I restored our Main domain controller from image now the backup domain controller cannot see it and I cant demote the backup domain. Users occasionally see the error 'Trust relationship has been lost with domain controller' when trying to log on to a domain controller. This can.
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. 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. Where you get netdom.

Turn off the Kerberos Key Distribution Center service. You can do this in the Services MMC snap-in. Set the startup type to Manual. Remove the Kerberos ticket cache.
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.

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. Right click on the computer that you are having trouble with.
