求救!~~~JDBC连接sql server问题,,,急
我的系统是windows server 2003
数据库是sql server 2000
已经安装了一个Microsoft SQL Server 2000 Driver for JDBC

然后已经把msbase.jar mssqlserver.jar msutil.jar 三个文件放到j2sdk的lib下了.我用一个JCreator 写一个连接数据库的程序.程序如下:
import java.sql.*;

public class DTool{
  //Connection conn;
  public static void main(String[] args) {
  try {
  Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
  Connection conn=DriverManager.getConnection("jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=pubs","sa","123");
  System.out.println("连接成功!");
  }
  catch(Exception e){
  e.printStackTrace();
  }
  }
}

编译时没错,可运行时出现如下错误:
--------------------Configuration: <Default>--------------------
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket.
  at com.microsoft.jdbc.base.BaseExceptions.createException(Unknown Source)
  at com.microsoft.jdbc.base.BaseExceptions.getException(Unknown Source)

  at java.sql.DriverManager.getConnection(DriverManager.java:512)
  at java.sql.DriverManager.getConnection(DriverManager.java:171)
  at DTool.main(DTool.java:8)

Process completed.

打上数据库SP3补丁应该就可以解决了
