To manage the Microsoft SQL Server and SQL Server Agent Services, use either SQL Server Configuration Manager or SQL Server Management Studio. Manage the services on clustered servers with the Cluster Administrator.
To manage the SQL Server service and set the server configuration options, you must be a member of the serveradmin fixed server role or the sysadmin fixed server role. Members of the Windows Administrators group can start and stop services and configure the server options that Windows provides.
