In my rush to get a demo network setup for a customer I was trying to install Microsoft Exchange 2007 onto a Windows 2008 R2 Server and got this error: “the system cannot find the file specified”.
Fix: All you need to do is install the RSAT tools for the OS you are installing it to. For Windows 2008 R2 just go to server manager, features, add features, then add the remote administration tools.
