During deployment of Microsoft Dynamics AX 2009 Workflow on one of environments running on Windows Server 2008 R2 I was able to validate Workflow URL in Basic > Setup > Settings for workflow. I was also able to access Workflow page from AOS server, but when running the workflow processing batch job I got an error in the Windows Event viewer for Microsoft Dynamics Ax Workflow:
| Exception thrown in SysWorkflowEventDispatcher-onAcknowledgeWorkflowActivation SysWorkflowEventDispatcher-raiseWorkflowActivationEvent : Web service failed: workflow id 000048_201 System.Web.Services.Protocols.SoapException: Server was unable to process request. —> System.ComponentModel.Win32Exception: Access is denied |

The error was caused by IIS Authentication settings where not only Windows authentication was Enabled but also Basic. To resolve this issue we followed the following steps:
– Log in as a local administrator on the Windows Server 2008 R2, and run Start -> All Programs -> Administrative Tools -> Internet Information Services (IIS) Manager
– In the left-hand pane, click on Sites, and then click on MicrosoftDynamicsAXWorkflow50 web application
– From the right-pane in IIS section double click Authentication
– Make sure that Basic Authentication is disabled
