Without an NT server, it is not possible using the NETBEUI protocol. It is possible using TCP/IP.

InterBase isn't a file-sharing database, so the Windows file-sharing model is not applicable.

No, the TIB_Connection component does all that for you automatically. For your part, you need to make sure of the following:

1a. You use the correct syntax in your client app for connecting to the server via TCP/IP. This is:
Servername:C:\database_path\MyDatabase.gdb

Achieve this by putting the Servername in the Server property and C:\database_path\MyDatabase.gdb in the Path property. Windows shares are NOT valid. It must be the physical path as seen on the server machine.

No variations are on this format are safe.

1b. You can also change the IB_Connection's Protocol property to cpTCP_IP if you like to dot the i's and cross the t's. However, the component is smart enough to work this out for itself if the Server and
2. The clients must be set up to find the server Servername (can be whatever you like) on the network. To do this, add an entry to each client's HOSTS file:

10.0.0.1 ServerName

The HOSTS file on Win9x (if it exists) is located in the Windows\System folder. If it doesn't exist, create it by making a copy of the file Hosts.sam and renaming it to HOSTS (no suffix).

Apart from that, your TCP/IP diagnostics look just fine.
