help about oracle client 8.0.3 with win98 and visual c++6.0

         My platform is Windows 98 with visual studio 6.0(include vc6,vb6...),

         the Oracle Server is 8.0.3 in NT 4.0 SP3,
         later I install the oracle 8.0.3.0.0 client,
         when I try to setup the SQLNET 8.0.3 easy configuration,
         the setup option is as follow:
           network protocal:TCP/IP
           port number:1521
         Then I run the test service,
         a error message occured as follow:
