How to backup databases with an environment with a centralize DB server and no server machine?

SOLVED

Our environment is set without a server, except the DB that is on centralize DB server and a licence server.

Applications are installed on workstation of users and they rely on DB server and license server.

I try to do backup with Management Console on the license server, but I have the same error.

Important! You are not running estimating Management Console on the Server.
