Some users have received a black screen when attempting to connect to various systems (primarily those running Windows Vista) via the Remote Desktop protocol (RDP). In some cases, the host machine may crash when this problem occurs.
Other users have reported receiving the error “atbroker.exe crashed” or “Transitions Accessible technologies between desktops has stopped working”
Make sure updates are installed, not waiting It appears that, in some cases, this problem may occur when updates are downloaded, but not installed in Windows Update on the host machine (the one receiving the connection). Try installing any pending updates then restarting the system.
Uninstall drivers Try uninstalling any recently installed third-party drivers, or drivers that you installed right before the problem started to occur, then restart. To do this, click the Start button then navigate to Control Panel > System and Security > Device Manager. Right-click any recently installed third-party items and select “Uninstall” then restart. Some users have reported that the Logitech QuickCam driver may be to blame.
Update to Windows Vista SP2 Some Windows Vista SP2 beta testers have reported that updating to the new release resolves this issue. Unfortunately, SP2 is not yet publicly available, but is available in final form to TechNet subscribers.
