请问怎么修改呢? 我是刚刚学这个的~初学者 能否说得详细点呢? 谢谢了!!!

使用Visual Web Developer 2005 Express Edition调试 Asp.net简单留言板源码，进入主页输入用户名/密码/验证码，51aspx/51aspx 出现下面的出错提示 数据库链接成功，provider: 命名管道提供程序, error: 0 - 管道的另一端上无任何进程 A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)

顺着出错向导至帮助信息 InnerException {"Cannot open database \"LeavewordDB\" requested by the login. The login failed.\r\nLogin failed for user 'sa'."}
