Error message on start up: The connection to the server has been lost. The application will close.

We're using NAV 2013 with NAV users (not windows authentication).

We've installed NAV 2013 on 4 new computers. On 3 computers (and all previous installed computers) NAV is working smoothly. Only 1 computer can't connect to the NAV database.

On startup, after typing the connection string, NAV shows all companies in the database. Then we select a company. After choosing a company, we have to re-enter the username and password.
After entering the username and password. NAV gives the error: "The connection to the server has been lost. The application will close."

We followed the same installation procedure as we did with the other computers: Same installation DVD (= same version no.), same certificates, same client-configuration file. We always use the same account to test whether we can log in. On the 3 new computers and the previous installed computers we can log in with our account, only on this computer we can't log-in. The user has super rights within the NAV database.
Using another user account doesn't make a difference.

When we type a wrong username and password, NAV gives the correct message that the username and password isn't correct.

We've also reïnstalled NAV, certificates: no solution.

Does anyone know what causes this problem and how we can resolve this?
