Hello Milos, Thanks for information. But I don't have any credentials and any rights to reset Account from Domain controller. And can't able to delete account from Domain and rejoin. Here my main intention is I don't want to delete account and rejoin. The way which I want is To do it by myself from client PC side Not from Server or Domain side. Kindly tell the way which am looking ? Regards, Avis

Hi Avis, Regarding the error message Trust Relationship between Workstation and Primary Domain failed, this issue can occur if the computer's machine account has the incorrect role or its password has become mismatched with that of the domain database. Please refer to the following articles to troubleshoot the issue. Trust Relationship Between Workstation and Domain Fails Trust relationship error.
