Strange Remote Desktop Behavior with Dual Monitors.
I posted this at http://social.answers.microsoft.com/Forums/en-US/w7programs/thread/e2c6ebd2-d02f-4fa6-9ff3-da66889099b8, but was directed to post here... Unlike some of the Remote Desktop Connection problems, this one is a bit more obscure and hard to recreate except for this one user's computer and I have no idea how it happens... Symptom: User with a Laptop and a Desktop Monitor, the Monitor a 23" screen while the laptop is a 15" screen, so the resolutions are not the same as the setup is for the Desktop Monitor acts as the primary and the Laptop secondary as an extended desktop. When connected to a Windows 2008 R2 server, using the "Use all my monitors for the remote session", the user has both monitors, however, when moving the cursor from the Desktop Monitor screen to an area that is not part of the desktop for the Laptop, the image of the desktop 'pans', such that you see the part of the Laptop desktop scrolling onto the Desktop screen. Sometimes, depending on the position of the Laptop's Display location, you can shift the screen so that the Windows 7 Task bar shows on the main desktop screen. This is only affecting one user, and I cannot seem to replicate it on another similar laptop nor have been able to identify what is making Remote Desktop Connection act like this. Having the user not have this checked, obviously does not allow the problem to occur.

Hi, Thanks for the post! Firstly, I recommend you update the video card driver and the BIOS to the latest one to check if the issue persists. Then, since I cannot reproduce the issue, please refer to this article: Using Multiple Monitors in Remote Desktop Session , there are some restrictions when using multiple monitors. For example, RDP restricts the maximum resolution to 4096 X 2048 per monitor. What do you mean “This is only affecting one user”? How about other users logging on this computer? What’s the kind of this user? Administrator or standard user? Do you have any domain group policy manage the user account?

1) Video Drivers are current. 2) Resolutions were only maximum to the resolution of the screens in question, so 1920x1080 for the Desktop screen and I believe 1124x800 for the laptop screen (I might be off on the laptop screen, but know it was definitely smaller than the desktop monitor) 3) I also tried to replicate the problem on a similar laptop, using the same system image used on the other user's system. Could not replicate the issue, however, was consistently seeing the user able to run into the problem where user would log into the terminal server running on the Windows 2008 R2 server, and moving the literal desktop screen when moving the cursor towards an edge that is not part of the laptop's boundaries, making both screens pan. I could not replicate this with the laptop I tried setting up the same way as the user. 4) No one else has reported this issue. We have several Windows XP users, and I tried to replicate it myself on two other machines with no similar result, but user with her system can get it consistantly. 5) The user is an administrator to her own computer, but not on the terminal server. Her fellow compatriots are the same. I have Admin rights on both as well as another IT user on our own systems and did not get the same reaction. 6) From what I can tell, we do not have any group that specifically affects this user that isn't applied to other users, myself included.
