RDP Problems with XP SP3?

Some users on the network have reported problems with Remote Desktop after installing Windows XP Service Pack 3. I couldn't get too many details since I'm in the software development division and the problems are reported to the technical support division and a rollback was already performed for the affected users. My Remote Desktop seems to be working just fine. In fact, I've also got the username and saved credentials information from the SP3 version as seen in this screenshot:



Has anyone else had problems with Remote Desktop after installing Windows XP Service Pack 3? Any idea what they are related to and how to resolve them?

EDIT: XP SP3 causes a problem with accessing remote desktop through Internet Explorer as the ActiveX control gets disabled. To get around this, you can Enable the Add-On "Terminal Services ActiveX control" in Internet Explorer 7 - if you are unable to see this add-on listed, you have to delete the following registry keys:
HKCU\Software\Microsoft\Windows\CurrentVersion\Ext\Settings\{7390f3d8-0439-4c05-91e3-cf5cb290c3d0}
HKCU\Software\Microsoft\Windows\CurrentVersion\Ext\Settings\{4eb89ff4-7f78-4a0f-8b8d-2bf02e94e4b2)

If you're trying to enable concurrent remote desktop connections to Windows XP SP3, see the article here.
