With Windows Vista I had to install the Admin Pack for Windows Server and then run a cmd file to register a load of DLL’s I tried this fix with Windows 7 but it didn’t work. I then found out that there was a tool created for Windows 7 Beta called Remote Server Admin Tools (RSAT) for Windows 7 Beta, so I downloaded this and installed

After the install I went into my Administrative Tools menu but I could not see anything. It turned out what I needed to do was to add these in through the Programs and Features (as this was not an added feature of Windows 7)
So what you need to do is to go into Control Panel, Programs and Features, Turn Windows features on or off and then select the Remote Server Admin Tools option:
I added all the options in there as I wanted to see what there was but you only need to select the tools you specifically require.
At the moment I am still having no luck installing Exchange System Manager on Windows 7 so if anyone knows how to please get in touch.
