Problems with Process.Start -- asp.net security

I am trying to run an exe from my .net 2 website but I cannot get
even simple code to work outside of Visual studio debug

very simple example (but my exe behaves the same)

Dim myprocess As New Process
myprocess.StartInfo.FileName = ("Notepad.exe")

myprocess.Start()

In debug this open up a new notepad window - good - that is what I
want

But , using a browser, notepad does not show up. It does start since I
can see it in the task manager.

This suggests insufficient permissions with ASPNET but the examples on
the web suggest that this simple code should work anyway.

Am I missing something here?
Do I need to delve into impersonation etc or is there something wrong
with my IIS setup?

Suggestions would be much appreciated

Thanks

If the process shows up in task manager, why do you think it didn't start?
Obviously, it did or it wouldn't be there. :) The problem here is that it
didn't show up in the same window station that you are in, so you don't see
the GUI because it was started by a different identity.

The thing to know about starting processes from within a web app is that
they MUST show no UI or require input from anyone or it will just sit there.
You don't want this. Notepad is a "semi-inappropriate" app to use for
testing with this since it is a GUI app.
