XP SP3 breaks ActiveX in IE 7

A client recently contacted me to report that he lost the ability to use the Remote Web Workplace feature of Small Business Server 2003 after having installed SP3 for Windows XP. It took a while of troubleshooting and some digging into Google Groups, but I soon found reports that SP3 will disable the Remote Desktop add-on of Internet Explorer 7 (perhaps also IE 6, but unsure at this time).

To fix this problem, go into IE's Tools > Internet Options > Programs > Manage Add-Ons and locate the Remote Desktop add-on. If it is set to Disabled, then enable it and your problem should be cured.
