The security database on the server does not have a computer account for this workstation trust relationship

Please help - Four machines with Windows 2008 R2, I encountered a login problem. I'm getting the message "The security database on the server does not have a computer account for this workstation trust relationship." Previously, I used the account 'CN\Administrator' to log on windows. But today I made some update to 'Domains and trusts' in domain controller(my domain is cn.xx.com) and reboot my comuputer. After reboot, I can't logon my comupter with above error message.

I tried to use account adiministrator@cn.xx.com to log on, but failed. I also used other accounts that created in domain controller, but also failed.

Now I have no way to log in my comupter, How can I log into my computer?

 

Any help would be appreciated.

Best wishes

Frank
