It looks like you are using the System account for the IIS process model. This is not an account that SQL Server can use for login to the database.

We'd recommend uninstalling and reinstalling, using the machine account (Network Service) for the IIS Process model. Also, if SQL Server is on a different machine than the Vault Pro Server, use SQL Server authentication in the SQL Server setup portion of the installation.

Another option is to use a Custom (domain) account for the IIS Process Model. Then you can use either Windows or SQL Server authentication.
