I currently manage a large implementation of Remote Desktop Services (RDS).  It is currently running Windows Server 2012R2 session hosts and Windows Server 2016 connection brokers. (We are in the process of upgrading.)  After doing the lastest round of Windows Updates we were unable to manage RDS in Server Manager.

The error we were getting in Server Manager was:

The exception unknown software exception (0xe0434352) occurred in the application at location 0x00007FFAF3A84048.

To find the session host causing the issues i needed to:

  1. Delete the Server Manager list file from: C:\Users\\AppData\Roaming\Microsoft\Windows\ServerManager\
  2. Now launch Server Manager and start to add back your session hosts until one crashes the console.  If deleting the file did not work you may need to delete your user accounts Windows Profile.
  3. Now connect to the Session Host you found that is causing the issues.

I found that on this server Server Manager would just spin when opened.  In the Event Viewer I found the following error:

To fix the server I had to open Regedit.exe and rename this key:




I then rebooted the server and everything started working.  I could then add the servers to my connection broker without issue.
