I have some forms published on my server in an intranet website.  The users
access the forms via my asp.net website.  The website is not a sharepoint
site, it is just a web application.  The users are able to open the forms ok
the first time, as they are just opening the xsn file.  When the form is
submited to my webservice, I take the full xml and save it in the database.
The next time the user wants to view and/or edit the form they submitted, my
application retrieves the xml from the database, saves it to a temporary xml
file, and opens it.  The temporary xml files don't load without this error
message coming up:

This form cannot be filled out, either because you do not have adequate
permissions, another user has the form open, or the form is open in another
program.
Do you want to open a read-only version of this form?

Does anyone know how to get rid of this message?  I didn't get this message
when I was working on my development machine. It only started after I
uploaded the website to the intranet server, and published all my forms
there.
