2.4. Windows Firewall is blocking traffic Usually, when the KDS Configuration app is started for the first time, Windows will display a security alert message: Click "Allow Access" and follow the prompts to allow the required network traffic to pass through the firewall. If this was cancelled, simply restart the KDS app and the message will reappear. It is possible that this message will not display, for example if a prior version was previously installed. In this case you can either make firewall changes manually (if needed) or completely switch off the Windows firewall (please consult your IT department prior to making this decision), see next page.
