See MSKB 889085
I created a custom template that restrict the control panel icon that the user will see once login to there PC.
User Config\Admin Template\Control Panel...Show only specified control panel applets
I am able to add and remove icon that are there by default but when I try to add a SMS icon it doesn't appear.
Any help would be appreciated.
