    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;We enforce smart card logins into our VDI environment, and we use Dell 5070 thinOS clients with Win10 1803 instant clones and vGPU.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;We have a handful of users that run into smart card issues when they lock their session and try to unlock their session the smart card isn't read by the clients and they need to reboot the client.
