sql server 2005是否允许混合登录,你可能只允许windows认证
sqlserver 2005采用'sqlserver身份验证'去登录, 出错的原因是:'用户 'sa' 登录失败。该用户与可信 sql server 连接无关联'。
具体的方法是:
1:打开sql server manager管理器!在左面找到 ‘安全性’ 单击右键 选择‘新建”,“登录” 弹出一个对话框,在登录名中输入你的登录号,选择'sqlserver身份验证',并输入密码,可以把‘用户下次登录时必须修改密码’取消掉。 点击‘用户映射’,在右面选择要映射的,并在前面打勾!在下面一栏中‘db-owner’和‘public’前面打勾。然后点击'状态'在右面栏中选中"授予"、“启用”,这两项一般是默认的,但如果默认的不是此两项必须改过来,不然是连不上的!点击‘确定’。
2:找到sql服务器,在左栏中上面,单击右键,在弹出的菜单中选择“属性”命令。弹出一个对话框,单击“安全性”,在“服务器身份验证”下面选择“sql server和windows身份验证模式”,在前面打勾!记得这一步很重要,如果没有这一步你就别想登录成功!然后单击“确定”就可以了!
3:重新启动服务就可以选择sql server 身份验证模式登录了!输入刚才的用户名和密码就可以登录成功了!(重新启动服务)
