Hi all,
Searching the web, I've not found anyone who was able to successfully install the RSAT tools in Windows 7 using SCCM. Based on a post here http://trevorsullivan.net/2009/11/19/deploying-windows-7-rsat/, I've been able to successfully deploy the RSAT tools to Windows 7 SP1 x64 machines using SCCM. Here is how:
1. Download the RSAT tools from Microsoft from here: http://www.microsoft.com/download/en/details.aspx?id=7887
2. Create a package in SCCM with the attached .cmd file and the .msu file you downloaded from Microsoft.
3. Create an install program in SCCM with the following command line:
c:\windows\sysnative\cmd.exe /c "install.cmd"
4. Under requirements, select All x64 Windows 7
5. Under Environment, select that the program can run whether or not a user is logged on and run with administrative rights
6. Advertise with normal software distribution procedures.
This has worked for me, but might require some tweaking to suit your environment. The real key for me was realizing that you have to run the 64-bit versions of WUSA.exe and DISM.exe to install in 64-bit Windows (hence the calls to C:\Windows\Sysnative\cmd.exe)
Hope that helps.
