Symptoms
Affected Operating Systems:
- Dell ThinOS
- Dell Hybrid Client
Dell ThinOS and Dell Hybrid Client (DHC) users, running older versions of the operating system and Azure Virtual Desktop agent software, will experience frequent session disconnections after October 26. Windows 10 IoT Enterprise LTSC users are not impacted.
Cause
Microsoft has implemented Web Service enhancements to the Azure Virtual Desktop (AVD) Linux SDK that require customers to upgrade their AVD agent. Starting October 26, older AVD agents will no longer be able to connect to Microsoft Azure Web Services (also known as Kestrel
).
Resolution
To avoid service disruption, customers must update to the latest ThinOS (2306 or later) or DHC (2.5 or later) release and AVD agent package before October 26.
