Ensure 'Remote Admin Connections' Server Configuration Option is set to '0'

中等級 1自動化mssql

說明

The remote admin connections option controls whether a client application on a remote computer can use the Dedicated Administrator Connection (DAC). Clustered instances are not applicable and are reported compliant. Default: By default, this option is disabled (0), only local connections may use the DAC. Runs one sqlcmd query with its defaults (Windows authentication to the local default instance); set SQLCMDSERVER, SQLCMDUSER and SQLCMDPASSWORD for another instance or SQL authentication. Needs VIEW SERVER STATE / sysadmin-level read access.

預期輸出: compliant
