VS2008连接SQL2005问题,老连接不上。

自己电脑是服务器和客户机。
SQL我已经设置成了混合登陆模式,用户名和密码都是sa,而且SQL用sa已经登录成功了。
VS里连接用户名和密码我也是用的sa,数据库名也是对的,而且连接成功。
但是当我运行程序的时候就报错,说用户sa登录失败。
“/WebSite1”应用程序中的服务器错误。

这是报错信息。我在网上看了好多,都不能解决,麻烦大大们帮下忙。
DB层中的连接字符串是private string strConn = "server=(local);User ID=sa;Password=sa;database=TB001";
Web.config中的是<add key="strConn" value="server=(local);User ID=sa;Password=sa;database=TB001"/>

正确答案如下:

登录数据库的用户名和密码是否正确,配置是否正确
server=(local);User ID=sa;Password=sa;database=master
