The default Windows icons are preferred over custom shortcut icons.
Create a new shortcut element and add all the other information before selecting the icon file field. The Windows icons can be accessed, by browsing to the folder C:\Windows\system32\shell32.dll on the server or computer the Desktop Authority web page is open on, and selecting shell32.dll.
Next choose the option to load icons to populate the default Windows icons represented by binoculars. The icon index should now populate a series of numbers which correspond with the default Windows icons. Select the icon number then save the element. Edit the element and update the icon file field with a dynamic variable that points to C:\Windows\system32\shell32.dll on any workstation. This is $SystemRoot\System32\shell32.dll. Save the element and replicate. The selected icon will now appear on the target workstations.
