Please explain the presence of Metro on Windows Server 2012.
Why did you install Metro on your server? The default install options for Server 2012 and 2012R2 is the Core install which doesn't include Metro and is designed to be managed orimarly via Powershell or via Server Manager running on a workstation.
There is an option to install GUI components but that it primarly designed for Terminal Servers and similar environments where the server is expected to provide desktop sessions to end-users via Remote Desktop or RDWeb. As a result, the server GUI is made to look as much as possible like the client GUI.
Administrators are expected to use Powershell, and/or Server Manager and the Remote Server Admin toolkit (which consists mainly of various MMC snap-ins that haven't changed a whole lot in recent times.)
Indeed, managing servers via the Admin Toolpack running on workstations was preferred in most cases even back in the Server 2003 days and Powershell works really well for machines running Server 2008 or later.
