SQL server configuration manager
This tool is installed onto the computer’s All Programs menu and is used to enabled SQL services and protocols. If you first look at the settings for SQL Server Services, both the SQL Server Browser and the SQL Server services for the database instance are usually not enabled by default after installation. They can be started or stopped or otherwise configured by right-mouse clicking over them. In the example screen below, both services have been configured to run automatically when the computer is started.
After installation, some or all networking protocols may have been disabled by default. In the picture below, three of the four protocols are disabled.
After configuration, the Named Pipes and TCP/IP protocols have now been enabled (see example below). You may choose not to enable unused protocols for your own security reasons.
SQL Native Client protocols can also be configured in a similar way (see below).
