Q. How do I manage Windows Server 2012 instances from Windows 10?
A. You need to use the Windows 10 Remote Server Administration Tools (RSAT) from http://www.microsoft.com/en-us/download/details.aspx?id=45520. These tools support management of Windows Server 2008 and above (in varying levels of functionality) but updates are required on some of the older OS versions to enable the remote support. These updates are referenced in the aforementioned link.
