Server initialisation state 6001 or 21

When you start the Mediaplus Logon Server program for the first time the Server initialisation state is set to 6001.

The ENI Mediaplus service was unable to connect to the ENI licences server.

Check that the ENI Mediaplus service has been started and check the Application log for any errors concerning this service.
If the service has not started correctly, check the properties of the service to make sure that the account associated with the service has the necessary permissions to start a service (for example those of an Administrator account) and also that this account has the necessary permissions freely to access the Internet. Restart the service and the Logon Server.
If the problem persists, check that accessing the Internet does not require authentication.
