    Unable to talk to core. Authentication fails.

    Rosta Rookie

      Hello,

      recently I installed Management Suite 2016-3 on new server. Deployed agents on clients and Remote Control from server works fine. But when I am trying to use Remote Console for Remote control, then connection fails with message "Unable to talk to core. Authentication fails.".

      I did not have this problem with previous version of Management Suite, I used.

      Any idea, what might causing it, or possible source of additional log information?

          I would check the authentication method you are using for Remote Control in the agent settings. I would also check the connection between both the Core server and the client machine and if the Core server name is pingable by the client machine.

            I have tried to change settings in "Remote Control Settings->Security Settings->Remote control security settings" from "Integrated security" to "Local template" which I used in previous version, but without any effect.

             

            I can connect from Core Server to Client machine without any problems and both Core Server and Client Machines are discoverable and accessible on network.

              Hi,

               

              Any messages in the remotecontrol.dll.log in the LDLog share on the Core?

               

              Thanks,

              Frank

                Every unsuccessful attempt log record ends with this:

                Any idea what does it mean?

                  The problem was caused by using one account for running the console and another account for logging into it. So I had to add permissions, so I could login with account which I used to run the console.
