sql2005破解
在 SQL Server Management Studio 中，不打开其他 DAC，单击工具栏上的“数据库引擎查询”。
在“连接到数据库引擎”对话框的“服务器名称”框中，键入 ADMIN:，并在其后继续键入服务器实例的名称。例如，若要连接到名为 ACCT\PAYABLE 的服务器实例，请键入 ADMIN:ACCT\PAYABLE。
完成“身份验证”部分（提供 sysadmin 组成员的凭据），然后单击“连接”。将建立连接。
2 . -- DAC设置可以连接，
0 - 指明仅允许本地连接使用 DAC
1 - 指明允许远程连接使用 DAC
sp_configure ' remote admin connections ' , 1 ;
GO
RECONFIGURE ;

在STUDIO DAC模试下执行或在sqlcmd - A - o c:\ 1 .txt模式下执行，输出文件
