Surface Area Configuration for Features (DAC) - Database Engine
[This topic is pre-release documentation and is subject to change in future releases. Blank topics are included as placeholders.]
The dedicated administrator connection (DAC) allows an administrator to connect to a server to execute diagnostic functions or Transact-SQL statements. The DAC can be used when the Database Engine will not respond to regular connections. By default, this feature is only enabled for a local connection. Enable this option to use the DAC from a remote computer. On cluster configurations, you must enable this option to connect with the DAC.
Options
Enable remote DAC
If checked, the DAC is enabled from remote computers.For more information about the DAC, see Using a Dedicated Administrator Connection in SQL Server Books Online.
