If you search for "Role Management Tool" for Windows 2008 on Microsoft.com, chances are you won't find what you seek.
If you go to Google and type in that phrase you'll probably find the first site that comes up to be exactly what you are looking for.
I do not know why Microsoft makes things so different between each version of their software, but they do. The Role Management Tool allows you to add features to Windows such as .NET 3.5 which ships with Windows 2008 but apparently is not installed by default.
I like the idea about not having everything you don't neccessarily need and want installed and running, but I found the error message when I tried to download and install .Net 3.5 service pack 3 a bit cryptic. Why not just pop up a link to instructions that explain how to install it?
And why doesn't Microsoft search return a relevant answer that explains what the Role Management Tool is in Windows 2008?
Mysteries of life to ponder....
