I have a WCF service that places openXML files into a SharePoint library then calls the Word Automation Services JobDefinition's RunNow method in an attempt to immediately convert that openXML file to PDF.
I am getting an "Access Denied" error when we run this in our staging environment, but it works fine in our test environment. In test the WCF service is on the same server as the SharePoint instance, whereas in staging the two are separated.
Is there something that I should be adding to call the RunNow method from a different machine? What permissions are needed by the app pool identity itself to execute the RunNow method of the a SharePoint 2010 job definition?
