Windows Tcp client app can't connect W5200 server

Question

Hi Anyone can try to connect W5200 TCP server with windows’s client apps? I’m use the source of W5200_TCP_and_UDP_SampleCode_v1.3. And ping and AX1 loopback test are OK. I’m going to connect other TCP client application to W5200 server mode. But it’s not OK. I’m used windows socket api. Simple code is : CSocket socket; socket.Create(0); if(socket.Connect(_T(“192.168.x.x”), 5000)) AfxMessageBox(_T(“socket opend”)); else AfxMessageBox(_T(“socket not opend”)); here 192.168.x.x : server ip in W5200 Anyone help or advice me?

Hi, I think it is port number problem. Windows is hold port number before connected although socket is disconnected. So try to change port number every time when you want to connect. Thanks.
