InfoPath Dev

I haven't found a good answer to the error message:

This form cannot be opened because it requires the domain permission level and it currently has restricted permission.  Contact the form author to resolve the issue.

I have the form set to "Domain level", but why are some users not able to open it. 

 

Are the users on the same domain as where the form is located?  Is the form making any data connections to somewhere outside of the form's domain location?

Yes, they are all on the same domain.  No, the form is not making any data connections to somewhere outside of the form's domain location

Hi, I was tearing my hair out over this error as I'm testing my InfoPath 2003 forms for an upgrade to Office 2010. Found that disabling the SharepointOpenXMLDocuments add-on in IE made the issue go away for me. Though I'm admittedly still looking to see what new problems that will create for us. Hope this helps.
