The message Unable to start — server not found when trying to start the client, indicates that the client cannot find the database server on the network.
The network configuration parameters of your network driver on the client machine may be different from those on the server machine. For example, two Ethernet adapter cards should use a common frame type. For Novell NetWare, the frame type is specified in the net.cfg file. In Windows, look for the frame type setting in the Control Panel Network Settings.
Under the TCP/IP protocol, clients search for database servers by broadcasting a request. Such broadcasts typically do not pass through gateways, so any database server on a machine in another (sub)network, is not found. In this case, you must supply the host name of the machine on which the server is running using the -x server startup command line option. This is required to connect to NetWare servers over TCP.
Your network drivers or wiring is not installed properly.
