I am having trouble adding a InfoPath data connection to the SharePoint web services in an extranet environment. It worked fine in the internal (non-https) test environment.
"InfoPath could not open the XML document: Not enough storage is available to process this command."
Trying to add a data connection in InfoPath Designer, when I give a valid url (this same url works in the browser)
Once I click the Next button I get 2 popups.
I opened up Fiddler, and when I click the next button I see the request for the XML, and the proper XML response coming back on the third try after two 401 Unauthorized's.
