Error processing XML. The remote server returned an error: (401) Unauthorized

Hi,

I'm getting the following error when running a Scheduled workflow:

Error processing XML. The remote server returned an error: (401) Unauthorized

- The error is on an XML query action

- Im trying to query xml from an infopath form

- I am using a noredirect=true in the querysting

- I am providing explicit credentials on the action so it is not a double hop issue

- Worklfow works fine when I run manually, but fails when it runs under a schedule

 Any help would be greatly appreciated

Regards
