I recently realized that I have only one account (domain admin) that can log in locally to the Win 2012 Essentials server. One other domain admin account is or should be available, but when signing in the message "The User Profile service failed the sign in. User profile cannot be loaded". There is no profile in C:\users (I can view hidden files and folders). When I try to add a local user, it hangs on the Finish and I have to use Task Manager to end it. This is not a major issue today, but could definitely be a problem in the future.
Thanks for the help.
