Clients not checking in or checking in and then disappearing
Cloned images – SUSCLIENTID is not reset with Sysprep!!!
This needs to be done if your creating a template for Windows 2016 and Windows 10 in a virtual environment.
So if you have deployed servers from template already, do the following fix. Or if you realised before deployment, just delete the reg keys before converting the virtual machine to a template.
Solutions / Fix
Stop Windows Update service
Open up regedit
Browse to : computer\hklm\software\microsoft\windows\currentversion\windowsupdate
Delete susclientID
Delete susclientidvalid
Start Windows Update service
Open up command prompt as admin on the effected Window 2016 or Window 10 client, if the image has already been deployed
type
c:\windows\system32\UsoClient.exe RefreshSettings
The clients should then check in and create a new SusClientId and SusClientIdValidation
