workflow stop error (Event viewer error: failed to logon to AX)

Hi,

We are trying to create a workflow for project timesheet.  Workflow is setup but we submit the workflow then item queues are not created and we see the Workflow stop error.

I have checked the event viewer and I can see below error.

First Error:

Workflow threw an exception for the following reason: Failed to logon to Microsoft Dynamics AX.

Second Error:

Workflow Instance ID: 000123 mscorlib Failed to logon to Microsoft Dynamics AX.

I have checked the workflow execution account and it is set to admin account who has system admin role in AX.

Is there a way to resolve this?

Thanks in advance.
