If you receive the message Unable to start — server not found when trying to start the client, the client cannot find the database server on the network.
Check for the following problems:
The network configuration parameters of your network driver on the client machine are different from those on the server machine. For example, two Ethernet adapter cards should be using a common frame type. For Novell NetWare, the frame type is set in the net.cfg file. Under Windows 98, Windows NT, and Windows 2000, the settings are accessed through 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. If this is the 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 are not installed properly or the network wiring is not installed properly.
The network configuration parameters of your network driver are not compatible with Sybase IQ multi-user support.
