Anne,
Go to Start>Settings>ControlPanel>Add/Remove Programs, scroll down until you see Microsoft Internet Explorer 5 & Internet Tools, click the Add/Remove button and select repair.
If that doesn't work:
open Notepad and copy and paste the following between the lines and save the file as dragdrop.reg. Double-click on the file to merge the contents into the registry.
