I need to disable UAC on a Windows Server 2008 R2 domain controller, but I can't access its settings through the usual path (Control Panel -> User Accounts -> User Accounts), because a DC doesn't have a local user database, so the "User Accounts" icon in the Control Panel simply doesn't work.
How can I access the UI for UAC settings on a domain controller?
I know I can use a GPO for this, but I'd prefer to manually configure it on this single server.
