How much time between connections?  Can you post your code?

#include <Ethernet.h>


byte mac[] = {0xDE, 0xAD, 0xBE, 0xEF, 0xEF, 0xED };

int CurrentTime = 0;
const int TimeOutMax = 6000;

boolean DebugMode = true;

Server server = Server(23);


void setup()
{
 pinMode(StatusLED, OUTPUT);      // sets the digital pin as output
 digitalWrite(StatusLED, HIGH);
 pinMode(Learner, INPUT);
 pinMode(IR1, OUTPUT);
 pinMode(IR2, OUTPUT);

 digitalWrite(StatusLED, LOW);
 delay(200);
 Ethernet.begin(mac, ip);
 server.begin();
 digitalWrite(StatusLED, HIGH);
 Serial.begin(9600);
 
}

    Serial.println("Connected");
  }

  ReadyChar = client.read();
 
  if (ReadyChar == 0)
  {

  }
  if (ReadyChar == 255)
  {
      client.write(255);
      GetCommandData(client);  
      client.stop();
  }

There is more too it if you want to see it all, but there is normally 10 seconds between connections (sometimes a little less or more). I timed the code to get from the Serial.println("Not Connected"); back to that statement after it connects transfers data and does it thing then back to saying "Not Connected" normally takes about 400 ms.

What are you using to connect to the Arduino?  What exactly are you wanting it to do?

I'd try getting rid of that client.stop();

Seeing the rest of your code and knowing more about what you want to accomplish may help.

I will post the rest of it this evening, but I added the client.stop(); because it wasn't working (it didn't help)

I'm trying to send IR codes to the ardunio then have it flash an emitter to turn my TV on and off, I have an IPAQ running a .net app that takes a standard IR hex code converts it to number of burst pairs, clock speed, and an array or on times and off times. I want to send those to the arduino and once it has the complete information I want to it flash the emitter and send it (which all of that works) the problem comes when I want to send multiple IR codes in a row (example I want to scan though the guide or something ... pushing the guide button then the up or down arrow a couple times) thats when the .net application gets an error saying the arduino actively refused the connection
