SharePoint - How to resolve the security issue in infopath form 2007?

Hi All,

I got the below issue while opening the infopath 2007 form from SharePoint 2007 document library,

Error Message:

Your user name cannot be verified because the form's security settings do not permit it.
Error occurred during a call to property or method 'get-UserName'.

I am using the username() method to retrieve the user name filled out the form. How to resolve this issue?

Thanks & Regards,

 open each SharePoint site that you  are using in IE and look at the security zone for each site.  if there are difference between them.  The production site had "Local Intranet" and the development site had "Internet".  You can easily tell this by looking at the bottom right corner of the IE 7 browser.  if its like that then add the development site to the "Local Intranet" zone and then test your  InfoPath form out again and there will be no errors this time.
