Hello,
To accommodate Windows 10 with Credential Guard we want to create a new group policy that configures the Wired Network authentication to use PEAP with certificates on our W10 devices.
When I create this policy (Policies > Windows Settings > Wired Network Policies > Create a new wired network policy for Vista and later) things start to go wrong. After everything is configured and I check the Settings tab of the policy, nothing is shown in the overview as if there is no policy set. When adding another group policy setting in this same policy, like for example the Wired AutoConfig service to start automatically, then this does show up in the Settings overview.
After this new policy then replicated to all other DC's, things get worse. The policy is not shown anymore in the GP Management console but it's GUID is still available in AD under System > Policies and in the SYSVOL folder. See screenshot below.
We have older wireless and wired network policies for our W7 devices that are working fine and my newly created wireless policy for W10 devices is also working fine. Also I can still create new policies without any problem as long as I don't touch the wired settings.
Anyone seen this behaviour before?
