Can I have some help on Datasnap server-client connectivity problem. Using Delphi 2010 Enterprise IDE running on Window 7 (tried on 32 and 64 bit machine with similar problem) I tried to build Datasnap server/client according to the tutorial provided by Bob Swart 2009 white paper (Delphi2010 Datasnap: Your Data - where yu want it, how you want it'. In summary I created a Datasnap Server using VCL Forms Application selecting only TCP/IP and TDSServerModule. Everything is left at default. Port 211. DSServer autostart set to true. Build and compiled without problem. The server ran without a glitch. Check on Kapersky showed the server application was allowed.
I then followed that up with a new VCL form as client. Added in TSQLconnection using datasnap driver. Unfortuntely the BDE hanged everytime I try to connect SQLconnection at design time. TCPVIew showed Both BDS and server application has established connection at 211. The only way I can get out of this loop is to close and restore BDS and the following error showed. 'Window socket error: An existing connection was forcibly closed by the remote host (10054), on API 'recv'.
The stack trace attached.
