Answer 1

你只设置了windows登录，没有设置SQL Server登录和windows登录的混合模式

Answer 2

设置了...我用SQL Server Management Studio 登陆sa账户正常

Answer 3

用SQL Server Management Studio 登陆
身份验证：SQL Server身份身份验证
密码确认无误

Answer 4

选择登录方式和帐号 密码 全部对应着 在sql里面登录一下

Answer 5

右键左侧树最顶端->属性->安全性—>选择"SQL Server和Windows身份证模式"然后重启下电脑或重启下SQLServer服务

Answer 6

连接串用这个试下：
Server=(local);User id=sa;Pwd=sa;Database=master;

Answer 7

如果是安装的时候设置的sa密码，那么Windows登陆后再修改一次。重启服务即可
