在java中( 我使用 eclipse ) 远端连接数据库

代码如下
String username = "sa";
String passwd = "";
Strin jdbcClassName = "com.microsoft.jdbc.sqlserver.SQLServerDriver";
Strin dbUrl = "jdbc:microsoft:sqlserver://192.168.0.6:2433;databasename=jsp;";

Driver driver = (Driver)Class.forName(jdbcClassName).newInstance();
DriverManager.registerDriver(driver);


Connection dbConn = DriverManager.getConnection(dbUrl, username, passwd);


出错提示:

java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket.

请问如何解决 谢谢...
