Running Process on Server via ASP.NET/C# on IIS

Question

What I am trying to do is run a batch file that is located on the webserver's desktop when a button is clicked. This is what I have thus far.

ProcessStartInfo psi = new ProcessStartInfo("Notepad.exe");
   psi.WorkingDirectory = @"C:\Users\Administrator\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Accessories";
   psi.UseShellExecute = false;
   psi.UserName = "administrator";  //username
   psi.Password = secure;  //secure string
var process = Process.Start(psi);

When I debug it, it does exactly what I want it to, but when I access the site on IIS (localhost:81) the batch file never runs. I've tried many different variants of ProcessStartInfo and Process with no luck. I've tested the username and password and they are both correct too.

I don't get any errors, the button just triggers a page post back.

I have given IUSR and IIS_IUSRS permissions to the file, and still nothing runs. I also removed the username and password and set the UseShellExecute to true, but that did nothing as well.

EDIT:

It looks like everyone thinks its some permissions. Any idea on what I need to do to allow IIS to open the process?

Thanks in advance!

Just change the third line to this:

  psi.UseShellExecute = true;

or read this article which really gets the work done:
