Re: No connection could be made because the target machine actively refused it. - 'System.Net.Socket

The security would be on the server side for refusing it.

Using: [SocketPermission(SecurityAction.Demand, Unrestricted=true)] on the
method that opens the server socket would allow the TCPClient to contact it.

Thank you Grant. I am getting build errors when I insert your code so I am
reading about code access security. Thank you for pointing me in that
direction.
I will report back when I achieve success.

The following code;

TcpClient client = new TcpClient();
client.Connect("localhost", 9999);
Stream stream = client.GetStream();

causes the following exception as the attached .jpg shows;

"No connection could be made because the target machine actively refused it"

is this a code access security issue? how is it resolved?
thank you,
