When you start the Remote Desktop Web Connection window after installing Windows XP Service Pack 3, the following error may occur, and the Connect button remains grayed out:
Microsoft RDP ActiveX Control is disabled when you install Windows XP Service Pack 3 or Windows Small Business Server 2003 SP1. Follow one of the following methods to enable the ActiveX control.

Thank you Ben Blackmore, removing {9059f30f-4eb1-4bd2-9fdc-36f43a218f4a} after removing {7584c670-2274-4efb-b00b-d6aaba6d3850} made all the difference. I can use VPN again!
Thank You!! I encountered this problem with a new Acer AspireOne (xp home sp3 preloaded) with our existing SBS 2003 RWW. I spent nearly two days researching before I found this article. Deleting the registry key as you recommended fixed my problem immediately. I still had to fidgit a bit with the “trusted sites” security settings in IE7 to get the server to offer me the ActiveX control download. I had to change a couple more security settings to turn off prompting before the “unsigned” control is allowed to run without a pop-up box warning me that the website wants to start a remote session.
I also had to delete the extension GUID {9059f30f-4eb1-4bd2-9fdc-36f43a218f4a}, which is the TS Web Extension, to get it to work.
Can you use the remote access service on a mac?
Have XP SP3 and SBS 2003. Deleting the registry key worked for me. Thank you for your help. I would think many more people will have the same problem within the next few months. This fix is a keeper.
This worked for me…Thanks a bunch!
Do you have a fix if using https website and RDP?
Thank you for the great fix!
It worked like a charm
