Client Server - Establishing a Connection
One of the steps involved in configuring client/server systems is establishing a connection between the client, and server computers. Both machines must see each other on the network, with the appropriate ports open for communication to occur.
It can not be assumed that because two computers both see the internet in a web browser, that they'll necessarily be able to communicate with each other.
Testing for connectivity with Ping
From a command prompt, ping the name of the server machine from the client machine. If ping responds, then you have connectivity. If you have no connectivity, then you have a network configuration error, which you must resolve before moving on.
If you have connectivity the next step is to test the port you wish to connect to using telnet. Telnet Client and Server may need to be turned on in windows features, in order to use telnet.
Testing port 5190 using telnet.
c:\>Telnet "Ip address " 5190
If the connection can be made on the port you will receive the telnet screen and a cursor.
If you can not make a connection on the desired port, then you should verify that the ports are open on both computers in the windows firewall settings.
