В моей следующей программе я пытаюсь подключиться к серверу MSSQL, используя jdbc в Windows аутентификации. Но получаю следующую ошибку

import java.io.*;
import java.sql.*;
import java.util.GregorianCalendar;
import java.util.Date;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;

class  Cms_truncate
{
    public static void main(String[] args) 
    {
         Calendar cal = new GregorianCalendar();

         //String name="cmscim";
         //String filename = "D:\\programs\\Tomcat 6.0\\webapps\\timescape\\canteen_scheduller\\CMS_CSV\\cms_cim\\"+ name+"-"+cal.get(Calendar.YEAR) +"-" +(cal.get(Calendar.MONTH)+1) + "-"+cal.get(Calendar.DATE)+".csv";
         Connection conn = null;
         String url = "jdbc:sqlserver://localhost:1433;databasename=CMS_TIMES_MAIN;integratedSecurity=true";
         String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
         String userName = ""; 
         String password = "";
         Statement stmt;
         try
         {

         Class.forName(driver);//.newInstance();
         conn = DriverManager.getConnection(url,userName,password);
         String query = "select * from cim where sapId=10025331";
         stmt = conn.createStatement();
         int flag = stmt.executeUpdate(query);
         System.out.println("flag = "+flag); 
         conn.close();
        System.out.println("");
         } catch (Exception e) {
         e.printStackTrace();
         }

    }
}

Я использую SQL Server в режиме проверки подлинности Windows. Нужно ли настроить другие вещи для подключения MSSQL с помощью jdbc в Windows аутентификации.

ОШИБКА:

com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host localhost, port 1433 has failed. Error: "Connection refused: connect. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".
