My server was connected on Windows 7 environment and my client was installed on Windows Xp. The client could connect the server very easily. However the connection between the server and client broke around 30-minute use (have not counted). Are there any settings on either the server or client such that the connection is always connected with any breaks.

I don't know why the connection broke.
If the connection lose at a period of time, I think you may be able to avoid it.
Please try to set the number of TCP connections to about 10 and the establishing interval about 10 minutes.

Please check your NAT or firewall's setting. If there is a function to "cut-off too-long existing connection", it might be a cause.
