Embedded .net Windows Forms Control Security Issue

Hi,
I have been trying to use a .net Forms control in my webpage to open up
an application(notepad) on the client. The control works fine when
embedded in a windows form, but I keep getting a security exception
when trying to run it from my webpage on my intranet. I have tried
playing with the Code Access Security settings, but I can't get it to
work.
What do you think?

Thanks,
Gal

Exception:
System.Security.SecurityException: Request failed.
