I have change the Server name and after that i am not able to login the server showing trust login issue. i tried to disconnet the network adapter but same error is getting can you please help here

Changing the server name on a domain-joined machine can break the secure channel with the domain and cause the error “The trust relationship between this workstation and the primary domain failed.” This must be repaired from a local admin session.

Follow these steps on the affected server:

1. Sign in using a local administrator account
   • At the logon screen, use a local account in the form SERVERNAME\LocalAdmin.
2. Use PowerShell to test and repair the secure channel
   1. Open PowerShell as Administrator.
   2. Test the secure channel:

            Test-ComputerSecureChannel
      

      • If it returns False, continue.
   3. Attempt to repair the secure channel (you will need domain credentials with rights to reset the computer account):

            Test-ComputerSecureChannel -Repair -Credential (Get-Credential)
      

   4. If still not working, reset the computer account password and reboot:

            $credential = Get-Credential
            Reset-ComputerMachinePassword -Credential $credential
            Restart-Computer -Force
      

3. Alternative using Command Prompt (if PowerShell is not preferred)
   1. Open Command Prompt as Administrator.
   2. Verify the secure channel (replace placeholders):

            netdom verify ComputerName /domain:YourDomainName
      

   3. Reset the machine password (replace placeholders):

            netdom resetpwd /server:DomainControllerName /userd:Domain\Username /passwordd:*
      

   4. Reset the secure channel (replace placeholders):

            netdom reset /domain:YourDomainName /userd:DomainUsername /passwordd:*
      

   5. Restart the server.
4. If the trust issue persists after repair
   • After reboot, log on again with the local admin account and:
     • Remove the server from the domain (join to a workgroup), reboot.
     • Join it back to the domain with proper domain credentials, reboot again.

These steps repair the broken trust caused by the name change so domain logons and SCOM agent/management server communication can work again.
