If you are having problems getting your client application to communicate with a database server, you need to ensure that the client and the database server are using compatible protocol stacks.
A helpful method of isolating network communication problems is to work up the protocol stack, testing whether each level of communication is working properly.
If you can connect to the server computer in any way, then the data link layer is working, regardless of whether the connection is made using the same higher-layer protocols you will be using for Sybase IQ.
For example, you may want to try to connect to a disk drive on the computer running the database server from the computer running the client application.
Having verified that the data link layer is working, the next step is to verify that other applications using the same network and transport layers as Sybase IQ are working properly.
