Answer 1

For SQL Server 2019 Developer

In default installation:

• TCP/IP is disabled
• Authentication is set to Windows Authentication mode only

The Fix

1. To enable TCP/IP:

   Start Menu
    -> Microsoft SQL Server 2019
    -> SQL Server 2019 Configuration Manager 
    -> SQL Server Network Configuration 
    -> Protocols For MSSQLSERVER 
    -> TCP/IP
    -> Enable
   

2. To enable SQL Authentication mode:

    Start Menu
    -> Microsoft SQL Server Tools 
    -> Microsoft SQL Server Management Studio
    -> Right-Click the server node 
    -> Properties
    -> Security
    -> Under Authentication choose "SQL Server and Windows Authentication Mode"
   

3. The above changes needs restarting the "MSSQLSERVER" service.
