JBulider2006与SQL2000的连接问题~~~~急

[shixinyiran]

我的操作系统是Microsoft Windows XP Professional 版本2002 Service Pack2
在JBuilder2006中写好了数据库的连接程序,SQL2000单独运行正常,但是程序运行连接的时候就会报错,SQL2000已经打了SP3的补丁sql2ksp3,这是编译器报的错误,我是个初学者哪位大虾帮下忙,
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket.
