Windows Server Update Services: Windows 2016 Servers does not show up on WSUS console

Windows Server Update Services (WSUS): WSUS previously known as Software Update Services (SUS), is a computer program and network service developed by Microsoft Corporation that enables administrators to manage the distribution of updates and hotfixes released for Microsoft products to computers in a corporate environment

This happens most times because the servers are created from an AMI (never syspreped). For more information PowerShell and USOClient commands, see https://techdirectarchive.com/2020/02/05/handy-windows-server-update-services-commands-wauaclt-powershell-and-usoclient/

Note: All other servers are reporting to WSUS such as Windows server 2008R2 and Server 2012 R2 but Windows Server 2016 does not.

Note: All registry keys are created on Server 2016 and there is connectivity between the wsus server and the windows server.

Solution: Delete the SusClientID and SusClientIDvalidation keys from the registry. This is because the sever was created from a clown (AMI) and new ones will be generated automatically.
