So I had a question that prompted me to remind people about the setup for Workflow. The workflow in AX runs under the Windows Workflow foundation which is hosted, in AX2009, under IIS. This engine and the AOS communicate together to execute the workflow.
So if you have running the demos VMs and the workflows are in the queue but you they are not running for you then make sure you have the Webserver running on the demo VM.
To do this click Start\Control Panel\Administrative Tools\Services. Scroll down to “World Wide Web Publishing Service” and start this service.
