DenSter's:
You have your database file on the network, and someone is just connecting directly to the database file. This way only one session at a time can be connected. You are not connecting through the Navition Database Server.

You need to install the Navision Database Server, and when connecting to it, instead of browsing to the database file, you enter the server name and then it should find it automatically. Note that when you want to use the name your machine must know how to resolve it, so you need to add the IP address and port number to your hosts and services files. You can always use the server's IP address directly in the server name box when you connect the client.
