Today we have been playing with the Microsoft Deployment Toolkit and actually had a bit of a stuggle with it - Using the latest Windows Automated Installation Kit (WAIK) for Windows 7 with the previous version of MDT throws out an error something like the following:

"PEIMG.EXE IS NOT RECOGNIZED AS AN INTERNAL OR EXTERNAL COMMAND"

When you look in the location where MDT searches for the peimg.exe file, you will notice the file does not exist at all.

So what's happening here? Its actually quite simple - the AIK and PE Image in the Windows 7 environment has changed from Vista to use img files only.

In simple terms, there are 2 ways you can solve this error;

1. Download & Install the Windows Vista AIK on the MDT Computer
2. Download & Install MDT 2010 on the Computer

So basically the latest AIK is only compatible with the latest MDT...
