Microsoft SQL Server 说我的登录被禁用，即使在单用户/DAC 模式下

Question

我被锁定在本地数据库之外，过去对我有用的单用户模式选项在这里对我不起作用。我可以使用一些选项来尝试。

据说该帐户已被禁用，我认为这在单用户模式下是不可能的。

我已经尝试过的：

在单用户模式下重启：

C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBNAME\MSSQL\Binn>net stop MSSQL$DBNAME
The SQL Server (DBNAME) service is stopping..
The SQL Server (DBNAME) service was stopped successfully.


C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBNAME\MSSQL\Binn>.\sqlservr -sDBNAME -m -c

[seems to come up]

登录尝试如下所示：

C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBNAME\MSSQL\Binn>sqlcmd -S .\DBNAME
Msg 18470, Level 14, State 1, Server MY-PC\DBNAME, Line 1
Login failed for user 'My-PC\sarahg'. Reason: The account is disabled.

服务器输出：

2012-05-29 15:55:25.11 Logon       Error: 18470, Severity: 14, State: 1.
2012-05-29 15:55:25.11 Logon       Login failed for user 'My-PC\sarahg'. Reason: The account is disabled. [CLIENT: <local machine>]

在 DAC 模式下重新启动：

C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBNAME\MSSQL\Binn>.\sqlservr -sDBNAME -m -c -t 7806
... blah blah ...

2012-05-29 15:59:05.74 Server      Server named pipe provider is ready to accept connection on [ \\.\pipe\MSSQL$DBNAME\sql\query ].

登录尝试如下所示：

C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBNAME\MSSQL\Binn>sqlcmd -A -S .\DBNAME
Msg 18470, Level 14, State 1, Server MY-PC\DBNAME, Line 1
Login failed for user 'Mys-PC\sarahg'. Reason: The account is disabled.

使用服务器日志：

2012-05-29 16:00:24.86 Logon       Error: 18470, Severity: 14, State: 1.
2012-05-29 16:00:24.86 Logon       Login failed for user 'Mys-PC\sarahg'. Reason: The account is disabled. [CLIENT: 127.0.0.1]

非常欢迎任何帮助，

我遇到了完全相同的问题并尝试了这个解决方案并且它有效：使用 PSExec（从 Microsoft 免费下载）使用该NT AUTHORITY\SYSTEM帐户连接到实例。示例语法：

PsExec -s -i "C:\...\Tools\Binn\ManagementStudio\Ssms.exe"

这将作为具有本机系统管理员权限的 Windows 帐户启动 Management Studio，这将允许您切换到混合模式、启用 sa 帐户、重置 sa 帐户、添加您自己的 Windows 帐户作为管理员等。

但是请记住，您可能会违反某些合同，只是想注意一下。:)
