Issue
If you want to disable some toolbar buttons like the collaboration, sign or commenting buttons you must do this using application-level Javascript.
Solution
Place the following Javascript code inside a .js file in %ProgramFiles%\Adobe\Reader 9.0\Reader\JavaScripts to disable the toolbar buttons:
// [File - Create Adobe PDF Using Acrobat.com], plus toolbar button app.hideMenuItem("WebServices:CreatePDF"); app.hideToolbarButton("Weblink:CreatePDF"); // [File - Collaborate], plus toolbar button app.hideMenuItem("Annots:FileCollaboration"); app.hideToolbarButton("Annots:CollabToolButton"); app.hideToolbarButton("CommentTask"); app.hideToolbarButton("SigTaskButton");
Additional Information
To discover the names of the toolbar buttons and menu items you should save the following Javascript in a .js file in %ProgramFiles%\Adobe\Reader 9.0\Reader\JavaScripts. The Javascript console window will pop up when you start Reader and will list the buttons and menu items.
