Tests connectivity to all linked servers on specified SQL Server instances
Validates that linked servers are properly configured and accessible by attempting to establish connections to each one. This function iterates through all linked servers on the target instances and uses SQL Server's built-in TestConnection() method to verify connectivity. Returns detailed results including success/failure status and specific error messages for troubleshooting connection issues. Essential for validating linked server configurations after setup, during maintenance windows, or when diagnosing cross-server query failures.

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
