I want to be able to limit one of Task Sequences to only running on a Vista machine.  On the “Advanced” tab of the Task System Properties I’ve selected the “This task sequence can run only on the specified client platforms” radio button and then made sure I’ve only selected the Vista checkboxes.

However, I’m able to run my Task Sequence on any machines not just Vista.


If you are running your Task Sequence by either PXE booting or from boot media then this option is ignored which is why you are seeing this (it’s like you have the “This task sequence can run on any platform” radio button selected).
