5070, info missing in WMS

Hi,

I have three Wyse 5070's, all on WES, that are showing in WMS with missing info. They all show offline, though they are up, and you can use VNC to remotely connect to them. The are also missing the Serial Number/Tag, and "Last User" info.

Things I have tried to resolve the issue:

- Unregister/Register (both from WMS & from WDA)

- Clear out the following in the CCMProtocolConfig.xml:  strip out the MAC Address, Owner ID, Wyse ID, Authentication Code and Group Key, save and reboot (while write filter was off)

- Re-image with newest Win 10 IoT Enterprise 2019 LTSC

- Re-image with original Win 10 IoT Enterprise 2016 LTSC

*** When re-imaging, I also applied the steps above to each OS version.

Anyone know how to resolve the issue?
