SQLServerName = DESKTOP-61QJQ77
or
SQLServerName = (local)
Is your database is on the same machine? If yes use (local) and your SQL Server password is 1234?. Try to connect to your database using mssql management studio. Connect to (local) or PC-NAME\USER then login as sa, and your password if you successfully logged in to the database engine. Then use the same credentials to dataserver.
Basically IGCN S9 and S12 has same configuration in-terms of DB connection.
Have a great day!
