Captive Portal Page Display Error from Devices Using Kaspersky 2016

Scope
Version: All
Solution

Version: All

 
Issue: Using Kaspersky 2016 on hosts in registration will lead to inconsistent and unpredictable results. The browser redirect displays "ERR_CONNECTION_RESET".

Kaspersky 16 has a feature called Kaspersky Security Network (KSN).  With KSN enabled, Kaspersky 16 detects the Network Sentry DNS redirect to captive portal as not secure and produces an error.


Workaround: Disable the Kaspersky product until the device is registered.
Solution:  This behavior has been documented as a Known Anomaly.  A complete list of Known Anomalies is available in the Customer Portal.
