I wish I could turn it off in off from our GP. Base on our PCI rules require us to follow the CIS to aduit "Success/Failures" on this one.

Are these Events considered a "Red Flag" or a threat? I see that this event shows a 'Windows Firewall' change.

Hi wchew, Thanks for posting here. Have you recently modified any setting on this hosts? Maybe like software/hotfix installation..etc. ? These audit records indicate that the windows firewall policy “Core Networking - Router Advertisement (ICMPv6-Out)” has been just changed , but we can’t determent the root cause without further information yet.

No, we haven't modified the host other than regular windows updates. This is a workstation with applications like Office, IM, HP printer app, and a syslog agent from Trustwave. Most of the users work is just using the web application and office. The OS is Vista Enterprise and similar problems with Win7 Pro. This is on a Group Policy, so may be one of the reasons why Vista and Win7 are both having problems. We haven't had any updates to the network/Switches/Router either.
