Answer 1

Have you really installed SQL Server database engine or only the tool SSMS = "SQL Server Management Studio"?

Is SQL Server service running at all?

Which Edition have you installed? By default the free Express Edition gets installed as "named instance" and you hve to add the instance name to the machine name, lik

MACHINENAME\SQLEXPRESS

Answer 2

Hi @Mohamed El Sayed Mohamed

From this doc: Error when you use SQL Server Configuration Manager to restart the SQL Server Agent service in SQL Server

Try this workaround:

Start the SQL Server Agent service by using the Services management console (Services.msc).
