Hi,
My problem deals with Web Service & System.Net.WebPermission

I created an InfoPath Visual C# projet with Visual Studio 2k3 and added a
form (called toto).
When the form is load a Web Service is called to retreive data stored in a
DB (this is not the issue).

In design mode I can preview the form. The Web Service return the desired
informations.
Everything work fine.
Then I published the form on a shared directory
(\\SERVER\SHARE$\DIRECTORY\toto.xsn)

When I double click on \\SERVER\SHARE$\DIRECTORY\toto.xsn I obtain the
hereunder error

System.Security.SecurityException
