|What is currently displayed at the very top of the page? Does the IE window take up the entire screen? If it does, press the F11 key, does that bring the toolbars back?|
If there is something displayed at the top but you're missing some items, try right clicking, that should bring up a list of choices - Menu bar, Favorites bar, etc. Put a check next to the ones you want, uncheck what you don't want.
