Group Policy Management about:security_mmc

cn flag

In Group Policy Management, when I click on an existing GPO, I get an Internet Explorer Enhanced Security Configuration messaged that "about:security_mmc.exe" is not a trusted site.

Error received when selecting a GPO

It happens every time I click a different GPO. I read to add this to the trusted site list, which I did. I confirmed it is in the policy when I do gpresult.

GPResult

But I'm still getting this message. Anything else I need to do so this doesn't keep popping up?

That usually means the host has Internet Explorer protected mode enabled.

@GregAskew There should be a way to have protected mode enabled and not have this pop up. In an environment where I was not involved the the Domain level configuration, I do not get this problem on servers that have protected mode enabled.

When you say you added it to trusted sites, did you add it within the GPO only or manually on the server itself? If you added it via GPO, it may take some time to replicate to that server.

You can run rsop.msc to check your applied group policies.

You can check IE trusted sites on the local server as well(settings)

I added it via GPO more than a week ago. My Internet Option settings are grayed out, so I cannot check there. When I run rsop.msc, I do see it listed there as I expect it would.

As soon as you use Site to Zone Assignment List in a (computer) GPO: everything else is blocked including the built-in ones, and you cannot see the list.

I have to do some test to pinpoint exactly where this comes from but long story short: prefer using (user-side) Zone mapping GPO that is simply adding registry entries.

JJStellato's answer from this social TechNet post helped me figure it out. As well as the last reply from Alan Burchill.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
