Error Message: Invalid Connection String Setting

Scenario

Upon launching the Delta Module Manager application, the following error message (or similar) is displayed:

Note: After pressing 'OK', the 'DMM Connection Strings' window appears

Reason

One or more of the connection strings is configured with the incorrect server name and/or database.
A firewall on the SQL server is blocking access to the database.
The Active Directory account which is logged on to Windows does not have permission to the Report~Pro database objects.

Resolution

Check each connection string by clicking the ‘Set’ button.
If a firewall is active on the server, open inbound port ‘TCP/1433’.
Add the Active Directory account to the security group which was created during the Report~Pro installation, typically called ‘DomainName/DMMGroup’.
