Access Denied Message on Form open

Good morning,

I've done some Google-research on this and looked some of the books we have in the office. This is the issue.

InfoPath 2003 (11.8165.8221) SP3

XML form (ex: Form.xml) - distributed via email to users
XSN template (ex: template.xsn) stored in folder on an https webserver.
    - Template uses managed code written in Visual Studio 2003
    - Template has embedded data: 3MB XML file, used to populate various form controls
    - Template is published with a certificate and needs "Full Trust"

The template has been in use for about 15 months and has gone through 3-4 updates.

Process:
    Users open Form.xml, which reaches out to template.xsn and pulls down template
    embedded data and properties. Users fill out form and submit form data to a web service via a data connection.
    These users are usually not on our domain, they access the template from their own home internet connection.

Exception:
    When a user opens Form.xml, the progress bar appears showing that it's
    connecting to template.xsn the properties appear to be downloading
    but an error is thrown stating:

        InfoPath cannot open the following file: Form.xml.
        Access Denied.

This is a very non-intuitive message. The template information is not pulled and the form is not opened. Looking in the <user>\Local Settings\Application Data\MicroSoft\InfoPath\FormCache\ folder, the Guid-based folder which is supposed to contain the template information has not been created.

This does not appear to happen to all users, only some. Also, this seems to be a recent development. Our last template update was in February.

I'm not 100% but I don't think that this is neccessarily an InfoPath issue but I am no expert - there have been no changes in how we deploy new templates.

For those who are experts, have you received this error before?
If so, what can cause this error?
    * server-side setting change?
    * client-side setting change?
    * InfoPath deployment or template problem?

Any thoughts or ideas are much appreciated.

Thanks,

Jerry K
