Shortcuts cause Explorer error

Vista Business.

Start menu and Desktop application shortcuts cause a Windows Explorer error.
All Office 2007 shortcuts, for example. Popup window is titled Problem with
Shortcut but only displays garbage characters.

Is there any way to repair the links in all the shortcuts?
