Windows Server 2012 Remote Management

Windows Server 2012 allows you to manage multiple servers as long as they are enabled for remote management. You can also create server groups. Windows Server 2012 Remote Management

WMI DCOM and WinRM

Windows Server 2012 Remote Management uses the Windows Management Instrumentation (WMI) based queries and scripts that are executed through the Distributed Component Object Model (DCOM) or Windows Remote Managemnt (WinRM). DCOM is the older proprietary protocol for software communication over the network whereas WinRM is the MS implementation of an independent standard called the WS-Management protocol.

WMI over DCOM requires you to at least open the DCOM-In port on the remote server. By also enabling the All (NP-In, RPC and RPC-EPMAP) rules in the Remote Event Log Management group you should be able to run most MMC consoles or computer management to control a server over the network.

Windows Server 2012 Remote Management

WMI over WinRM has been available since Server 2008 most notably as the Windows Remote Shell (WinRS) cmdlet and also server manager in Windows Server 2012. WinRm is a service which is started automatically and requires the WinRM listener to be enabled on the destination machine. This can easily be achieved by running the command Winrm Quickconfig. Remember that remote management is enabled by default in Windows Server 2012. WinRM requires a single port to be open for communication, either port 5985 over HTTP or 5986 over HTTPS.

Configure-SMRemoting is the powershell equivalent of Winrm Quickconfig and configures only WinRM. Remember to open up the necessary DCOM ports manually if you want to use MMC consoles for remote management.

When using Windows Server 2012 Remote Management Sconfigis a command line tool which is implemented to configure WinRM on a Server Core version of Windows.

To manage remote servers running server 2008 (R2), the .NET framework 4 and the Windows Management Framework 3.0 updates need to be installed first. You also need to install the performance update mentioned in KB 2682011 in order to get performance updates for servers running Windows Server 2008 or Windows Server 2008 R2.
