I have two Windows Server 200 R2 in my Hyper-V Test environment. One has the role of a Domain Controller and the other is a normal server. In the AD I've created a User and added him to the Domain Admins. I've joined the other Server to the Domain and added my AD User to the local Admin Group but when I login with my AD user I have no Admin rights.
I have no Idea why. Maybe the problem has something to do with the User Access Control Policy on the DC? I have no Idea what else I can try to make my AD User having Admin rights on the Server (by the way, when I login with my AD User on the DC everything works fine: I have Admin rights on the DC, but not on the other server).
I would be happy for some suggestions what I can try to make this work.
