Determining What Kind of Network You Have
This section explains how to determine the network protocol that you should use with the database engine. If you already know what protocol or protocols are supported on your network, you can skip this section.
Database Engine on Windows
If your network is 100% Microsoft, and you have a database Server engine, then your network probably uses TCP/IP. The Server engine does not support NetBIOS.
You can run applications over SPX on Microsoft networks if the applications use only the PSQL MicroKernel Engine (Btrieve or ODBC).
If your network is 100% Microsoft, and you are using Workgroup engines, then you can use either NetBIOS or TCP/IP.
