Cannot open InfoPath 2003 form from SharePoint 2003

[Yan]

I created an InfoPath 2003 form that consumes a web service and also
references MSXML2. It works fine from the VS.NET environment. But after
published to the SharePoint 2003 site, it cannot be opened after I click
'Fill Out This Form'.

I got the following error message:
Form template:
http://localIntranet/sites/SiteName/InfoPathRTF/Forms/template.xsn
The form template is trying to access files and settings on your computer.
InfoPath cannot grant access to these files and settings because the form
template is not fully trusted.

I made this form as fully trusted during development on my computer and can
run this form from VS.NET. The default sharepoint site is also on the same
computer, why I still got above message?

Thanks a lot!

How did you give it full trust? Did you install it on your computer or sign
it with a digital certificate? If you publish it to SharePoint, you need to
sign it with a digital certificate when giving it full trust.

I digitally signed by a free certificate (just for test) and published to the
SharePoint on the same machine, the InfoPath form can be opened and works
fine from the SharePoint, on which I downloaded the certificate. But
accessing this SharePoint site from another machineand, I got a Security
Warning message when I tried to open the published InfoPath form.

I searched MSDN, It says it’s normal to get the warning message after
deploying the digitally signed InfoPath form:
"If the default form template has been digitally signed, InfoPath displays a
security warning about the digitally signed form template. Select Always
trust files from this publisher and open them automatically. Then click Open."

But for my case, the problem is the checkbox "Always trust files from this
publisher and open them automatically" IS NOT ENABLED. So the Open button
cannot be clicked.

Do you know why is that? Many Thanks!

I'm not sure why it is disabled. What kind of free certificate is this? The
test certificates you can generate in InfoPath or something else? Did you
already try generating/using a test cert in InfoPath?
