Windows server 2012 domain controller.
I installed the 9.5 update on June 2, did not see any issues with this for the client, updated to 9.501-5 on June 12 midnight, and Internet access is failing on multiple sites.
Can get to Google.ca
Cannot get to canada411.com - Too many http redirects message.
Turned off web filtering and the websites were available - but the client requires filtering.
Re-enabled and turned off AD SSO authentication and websites are available again with correct content being blocked.
Attempted to remove from and rejoin domain, but domain join failed.
Currently, I have the client functioning, but, I need to rejoin AD and resume SSO authentication.
