How to disable SMB version 1 within Windows Server 2012

Windows Server 2012 introduced a new version of the Server Message Block (SMB) protocol.  SMB version 3 includes new features such as encryption.  If your environment does not have any Windows XP or earlier clients, an option is available to disable SMB version 1 to improve security.  The PowerShell cmdlet Get-SmbServerConfiguration will offer information on the current status of SMB version 1 and 2.
