Socket Listen for single connection

P: n/a
I am writing an application that simulates a TCP device that only
accepts one connection at a time. For my application, I would like
connection requests to fail if one already exists. So far I have the
following code:

IPAddress ip = Dns.Resolve("localhost").AddressList[0];
Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream,
IPEndPoint ep = new IPEndPoint(ip, 2323);

Socket s1 = s.Accept();

It seems that Listen(0) does not work as expected. If I open a client
to this application and leave it idle, and then open up a second
client, it waits for the first client to finish. If I open a third
client, the conneciton fails as I would like it to. It seems to me that
Listen(0) is behaving as I expect Listen(1) should.

How can I prevent the second from waiting? I want it to fail
immediately. Any suggestions?
