We have a virtual Windows Server 2008 R2 x64 SP1 Remote Desktop server with a handful of users logging in from Wyse C10LE thin clients running the Linux-based Wyse ThinOS.
A user turned on automatic updates and the server automatically
installed updates and rebooted last night
When the users logged onto this server this morning, their display
settings were changed and their dual-displays were showing as one
large screen instead of two separate displays.
Users cannot change the display settings in a remote session.
Background Information and Troubleshooting
Uninstalled the Windows Server 2008 R2 updates that were installed last night and rebooted. I left the Security Updates in place, I only removed updates under the "Microsoft Windows" heading in Programs and Features
Adjusted the Wyse thin client RDP connection display settings
Tried to adjust Remote Desktop Session Host Configuration settings and Group Policy settings to ensure multiple displays can be used with remote connections.
- Windows Updates were installed by mistake
- Remote Desktop connections from our Wyse thin clients won't allow dual displays, shows one very wide display
- All Wyse and Windows display settings I can think of have been checked
- Some of the updates that were installed by mistake have been uninstalled and another reboot has been performed
