This code may work for what you want. You will need to modify it to your requirements, but it does allow 4 simultaneous connections. It may be a bit difficult to understand. It is not for the beginner.

Thanks again Surfer Tim. I am a beginner but i am willing to work for my goals. the code you gave me was for a W5100 Ethernet shield and mine is a W5200. I should have mentioned that. what would help me the most rite now would be if someone could tell or show me how to get my program on this site.
the code I have is a whole lot simpler lol.
Thx

#include <SPI.h>
#include <EthernetV2_0.h>


// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network.
// gateway and subnet are optional:
byte mac[] = { 
  0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192,168,x, x);
IPAddress gateway(192,168,x, x);
IPAddress subnet(255, 255, 255, 0);
IPAddress dnServer(192, 168, x, x);
EthernetServer server(xxxx);

void setup() {
  Ethernet.begin(mac, ip, gateway, subnet);
  Serial.println(Ethernet.localIP());
}

void loop() {
    }

I know i am new and this is not a verry exciting code but i think i am learning thank you guys.

That won't do it. Reload the example chat server code.
