The standard MS SQL driver 4.2 just doesn't work and using the JAR for 8 and 10 still doesn't allow Servoy to access the database.
The error says that a TCP/IP connection can't be initiated over port 1433. Yet SQL Configuration shows TCP/IP active and the system's firewalls are turned off.
Excel and other third party applications can access the SQL server (we used AdventureWorks as a test DB) but Servoy just refuses.
