  • The SQL server service is listening to port 1433. You can check this by using the following command:

netstat –a | find “1433”

if the SQL Server is not listening on port 1433, use the following steps:

    1. Open SQL Server Configuration Manage
    2. Expand the SQL Server Network configuration
    3. Click on the “Protocols for SQLEXP_VIM”. SQLEXP_VIM is the name of the SQL instance

After customizing the SQL file execute it and make sure the RSA database is created.
