If you missed the story over at We Got Served regarding XP SP3 and remote desktop, here’s the details.
Some users cannot get RDP connected through Internet Explorer after installing Service Pack 3 (SP3) on Windows XP machines due to the ActiveX control being disabled by default in the Service Pack. Luckily the Terminal Services can be re-enabled by the following method:
Click on Tools -> Manage Add-Ons -> Enable or Disable Add-Ons in IE to enable the Terminal Services ActiveX control. If you are unable to see/enable the Terminal Services ActiveX control in IE7 on XPSP3 as a workaround can you try deleting 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)
Once you delete these keys, the activeX control should be enabled in IE7.
