Citrix Reciever - Multiple Monitors w/ Different Resolutions - Right Mouse Clicks Not Recognized

Purpose:
This post is to assist in the resolution of right mouse clicks not being recognized on certain published apps when the endpoint device has multiple monitors that are different display sizes.

Symptom:
When the user launches a published application and is unable to right mouse click on certain portions of the application. I had this issue when the user would move the published app to their secondary monitor (in my case it was the left monitor) then one specific portion of the application would not recognize the right click of the mouse. However if the published app was moved to the primary monitor (right monitor) then it would behave correctly. 

Resolution:
What ended up fixing the issue was changing the display settings so that the left monitor was the primary monitor then adjusting the users Start Menu and Desktop icons to the right monitor. Once we did that the published app would recognize the right clicks on both monitors.

Citrix PVS - After Reverse Imaging Unable To Change Computer Name

Purpose:

Show the steps taken after reverse imaging a W2K8R2 Citrix PVS Target Device to fix the inability to rename the server and add back to the AD Domain

Symptom:

After the reverse imaging process is done, the machine removed from the domain, rebooted, name changed and rebooted again the name of the server doesn't change and the ability to add the machine back to the domain is grayed out.



Resolution:

In the registry navigate to the below location:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ComputerName

There are 2 subkeys called ActiveComputerName and ComputerName and within each of there are valumes called ComputerName. Verify that both have the new computer name.

On my issue the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ComputerName\ActiveComputerName\ComputerName value had the old computer name. I renamed the key and then restarted the computer.

Cause:
Computer account not updating correctly
