Based on one of the previous post Where is AdminPak in Windows 2008 and R2 ?
RSAT (Remote Server Administration Tools) is the replacement toolkit as the AdminPak before Win2008. You may also look for the RSAT in Win Server 2012 and 2012 R2. Here are the download link,
1) Remote Server Administration Tools for Windows 8
2) Remote Server Administration Tools for Windows 8.1
You may have some questions here as I could found from the internet as well. Where is the RSAT for Win7? Is there any RSAT in WinServer 2012 and R2 for Win7?
The answer is, No. Feel bad on this answer? Here is a mapping for the better view on different RSAT for different Server version.
Server 2008 –> Vista RSAT / Win7 RSAT
Server 2008 R2 –> Win7 RSAT
Server 2012 –> Win8 RSAT / Win8.1 RSAT
Server 2012 R2 –> Win8.1 RSAT
