Weird problem with Outlook, WebBrowser control and Windows Server 2003

[Nordiek, Christof]

I have an applaction, that is an addin for Outlook. It opens a form with a
WebBrowser control wich then shows a page from a Webserver. It works fine,
but when I installed it on Windows Server 2003 the page didn't get shown in
the WebBrowser control.

I have another application wich uses the same form, but is a standalone
Winform-Application. This works on both machines (my development PC with
Vista and the Windows Server 2003.

Does anyone have an idea, what this cuold be, or any hint where to search
further?

Thanks
Christof

Nordiek,

This probably has to do with the fact that internet explorer is locked
down on Windows Server 2003 and does not show pages which are not in the
trusted sites without confirmation. The WebBrowser control is based on IE,
and I wouldn't dobut that this is the reason.

If you make your site a trusted site, does it work?

Thanks for answering.

The site is trusted. Actually it is the machine itself. Also this wouldn't
declare, why it does work, if the application isn't an Outlook-AddIn.

May also ve caused by the Outlook-Version. The system where it runs, has
Outlook 2003, the other Outlook 2007.
