Process List Name with title works on local using IIS Express but not on IIS 7.5

Hi
  I have a piece of code that works fine on Development environment(IIS Express) but when I host aspx pages on IIS and run it does not returns any application title but returns only process name and processID(Handler)
Code is as follows
================================
  Dim p1 = Process.GetProcessesByName("iexplore")             For Each p In p1                 lblApp.Text = p.ToString                 If p.MainWindowTitle.Length > 0 Then                     sb = sb + "Windows Title:" + p.MainWindowTitle.ToString()   ''(Does not work on IIS 7.5)     &n ...
