GPO only works on authenticated users

I am trying to apply a group policy to select users. All of the select users are in a security group. The group policy includes user settings

I am applying the policy to an OU that includes the user i'm testing with (I've also tried on an OU where the computer is). After it is applied, I run gpresult /r and see that its not applied and it says:

Filtering: Not applied (Unknown Reason).

Digging deeper if I run gpresult /scope user /h rsop.html, it says that it's "inaccessible"

Strangely, if I remove my security group from the security filtering and add Authenticated Users, it works fine.

I've re-created the policy and the security group and still the same result.

Does anyone have any suggestions? I know I'm missing something. Are there additional permissions that need to be applied to the security group in AD?



There was a change in GPOs recently (security issue that was corrected in Windows Update KB3163622) that I'm pretty sure is what you're running into.

After the new security change, if Authenticated Users is not in the Delegation tab, the GPO won't work (period).

When you remove Authenticated Users from the Security Filter via the GUI, it ALSO removes it from the Delegation tab. This used to not be a problem, now it is. :)

So, after you remove Authenticated Users from the Security Filtering, add them (back) into the Delegation tab (Read-only access should be enough), and then continue editing you Security Filter as you wish.
