Not able to submit infoPath form from windows 7 system to sharpoint 2010 form library

 Hi All,

I have created a form library with an attached form template:

http://... /abList/DesignMessage/Forms/AllItems.aspx

By pressing onto “Add document”, the form to be filled out opens.

In the form a have a submit button to post back the filled out form to the form library.
On windows xp this works well. The form is stored back to the form library.

On windows 7 we get the following error message by pressing the submit button:
The form cannot be submitted to the following location:

http://..... /abList/DesignMessage/EAAD000118.xml

The URL 'DesignMessage/EAAD000118.xml' is invalid. It may refer to a nonexistent file or folder, or refer to a valid file or folder that is not in the current Web.

Please suggest if anybody has face the same issue.

Best regards,

Anitha Vyas
