Windows Server 2008 (R2) blog by Kurt Roggen [BE]

Microsoft Remote Server Administration Tools (RSAT) enables administrators to remotely manage roles and features in Windows Server 2008 R2 from a computer running Windows 7. 
It includes support for remote management of computers running a Server Core or Full Server installation of Windows Server 2008 R2.

Installing RSAT is a 2 step process:

1. Installing RSAT package
2. Enabling/Installing the RSAT snapins/features

Step 1. Installing the RSAT package

wusa Windows6.1-KB958830-x86.msu /quiet  (x86) or
wusa Windows6.1-KB958830-x64.msu /quiet  (x64)

After installing the RSAT update package - containing most feature and role based administration tools - these snapins are accessible through Control Panel/Programs & Features/Windows Features - for installation.

Step 2. Enabling the RSAT features/snapins

After installing the RSAT update package, enable all (required) RSAT features.  Similar like installing features and server roles in (Windows Server 2008 R2) Server Core, you can install the Windows 7 RSAT unattended using the CLI tool DISM (Deployment Image Servicing and Management).

DISM enumerates, installs, uninstalls, configures, and updates features and packages in Windows images. The commands that are available depend on the image being serviced and whether the image is offline or running (online).

To get a list of all available features:

dism /Online /Get-Features

To enable available features:

dism /Online /Enable-Feature /FeatureName:<FeatureName>

dism /Online /Enable-Feature:RemoteServerAdministrationTools
dism /Online /Enable-Feature:RemoteServerAdministrationTools-Roles-DHCP

Below you find a list of available feature names

With Windows Server 2008 R2 and Windows 7 RSAT, you will also be capable of managing remote servers (running Windows Server 2008 R2) using Server Manager through PowerShell remoting.  Server Roles/Features will be manageable using local and remote PowerShell 2.0 scripts. So, you will now find the Server Manager snapin as part of the Windows 7 RSAT.
