Can anyone help me with a data connection recipe for the following scenario:

Windows NT 2000 Prof with P.SQL 2000i SP3 Workgroup edition with 3 client
licenses
contains a database with DDF files.

My delphi 6 application must be able to connect to the db above when
installed on a Win98 client.  The app must also work on the server itself.
I need relation access with SQL support.

The following has not worked:
P.SQL 2000 SDK SP2 does not support Delphi 6.
TRDSConnection - TADODataSet - TDataSource works on the Win98 client (once
the client has the P.SQL2000 WG installed and a drive mapped to the DDF
files) but running on the server gives the following error:
EOleException: Object provider is not capable of performing the requested
operation.

Any solutions or recomendations greatly apreciated.
