Unable to connect Ethernet shield with Arduino Board

I am trying to connect Ethernet shield with Arduino board.I am using my office proxy network.When I ping on IP address assigned to Ethernet shield, it shows connection but web page doesn't open.The function EthernetClient client = server.available(); always giving false value i.e. client=0. Code is as below,
#include <SPI.h>
#include <Ethernet.h>
byte mac[] = {0x00, 0xAA, 0xBB, 0xCC, 0xDE, 0x02 }; //physical mac address
IPAddress ip(192, 168, 32, 3);
IPAddress myDns(192,168,32, 1);
IPAddress gateway(192, 168, 32,254);
IPAddress subnet(255, 255, 255, 0);
EthernetServer server=EthernetServer(80); //arduino server port
void setup()
{
Serial.begin(9600);
Ethernet.begin(mac, ip, gateway, subnet);
server.begin();
//enable serial data print
Serial.println("servertest1"); // so I can keep track of what is loaded
}
void loop()
{
// Create a client connection
EthernetClient client = server.available();
delay(1);
if (client)
{
while (client.connected())
{
if (client.available())
{
char c = client.read();
//read char by char HTTP request
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println();
client.println("");
client.println("");
client.println("TEST");
client.println("");
client.println("");
client.println("

DEMO WEB PAGE

");
client.println("");
client.println("");
}
delay(1);
client.stop();
}
}
}

how to tackle this problem.

Ethernet.begin(mac, ip, gateway, subnet);

should read

Ethernet.begin(mac, ip, myDns, gateway, subnet);
