I have many production InfoPath Service forms on running on SharePoint 2010 (no code). Something has happened to our SharePoint farm over the weekend, and now all calls to GetUserProfileByName are generating an error:
"You do not have permissions to access a web service that provides data required for this form to function correctly". I can't get to the SharePoint logs, and sys admins are occupied with other problem (Exchange, so maybe related).
SharePoint profiles are functioning. I'm not experienced in technical troubleshooting outside of InfoPath. Is there a way to see behind the scenes (ip addresses??) when clicking button in InfoPath browser form? I've heard of Fiddler but never used it - is that a possibility? Thank you!
