When Microsoft Internet Explorer 7 is installed on network pcs, it blocks access to Microsoft Access. Whether it's a automatic update from Microsoft or a manual install of explorer 7 it blocks users from accessing the Microsoft Access Database. I have to uninstall explorer 7 in order for users to access the database. I don't understand how a Microsoft product would block access to another Microsoft product. It will open access files that are not being used by other users. Only the main database that users log into will not open. Can anyone provide me with some insight on this situation. All users have Windows XP Pro and Office 2000.
