Internet Explorer 7 add-ons, such as ActiveX controls and browser toolbars, are used by some Web sites to provide an enhanced browsing experience. To determine whether the problem is caused by an add-on, run Internet Explorer 7 in "No Add-Ons" mode.

To do this, follow these steps:
Click Start, and then type Internet Explorer in the Start Search box.
Click Internet Explorer (No Add-Ons). Internet Explorer 7 opens without add-ons, toolbars, or plug-ins.
Test Internet Explorer to verify that it works correctly.

Are you opening the site in IE7, or following a link from another site? While accessing page are you using popup window which has scrollbar disabled which may cause to disappear scrollbar from IE.
