There is no Status property. That was a mistake on my part. It should have said State. If the state property is 0 then you are not connected. the connection is closed. It should be 7 if you are talking to one another.

As nothing else appears to be wrong and it is working with another protocol, it sounds like you have a problem with TCP. Can you ping the client from the server? Can you ping the other way?

From the server:
ping < IP address of the client >

From the client:
ping < IP address of the server >

If this works, you may have a problem witht he ports being used. Try another port.
