I have a domain user which I am going to use as a "test user" for a new project we are doing. However, I have Group Policies already setup for our domain. How do I exclude this one user from all the domain GPOs that are already in place. I put this one user in their own Security Group but I still believe somehow they are linked to NT AUTHORITY\Authenticated Users. Is there a simple way to exclude this user fro the GPOs?
