With SQL Server 2005 or 2008, Microsoft offers a new feature, the dedicated administrator connection. This configuration is intended to serve as a last means of defense to troubleshoot and kill the offending SQL Server processes as opposed to rebooting the server possibly causing database corruption and/or access violations. The DAC allows you to connect to the server and issue T-SQL commands to troubleshoot and correct the problem.
