The Windows Filtering Platform has blocked a packet.

We setup 4 new DC's in our AD domain after we updated our schema to 2008 R2. The 4 new DC's are standard builds with all the latest updates applied and now changes to the default firewall settings. In our security logs we are getting thousands of 5152 audit failures.

The Windows Filtering Platform has blocked a packet.

They are announcement broadcasts that are being dropped.
According to this article I should be able to disable these so my event logs stop filling up.


However, the logs start filling up again after a few hours or right away after a reboot. Looking for any suggestions out there. This article seems to be similar to what I have but it does not list R2 as one of the systems it is supposed to fix.

 Looking for someone who may have some experience with this.

This will lead you in the right direction. It looks like the enable feature it audited by default.

Sorry but I already listed that link in my original question but it does not solve the problem permanently as my question explains.

I found the issue to be a buried gpo setting under the Default Domain Policy. Computer Configuration, Policies, Windows Settings, Security Settings, windows firewall with Advanced Settings, domain profile, logging. Click Customize and set log dropped packets and log successful connections to No.
