Windows Server Update Services: Windows 2016 Servers does not show up on the 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).

- Important Areas to Master on WSUS (Installed and not applicable, Install 1/4, and Installed / Not applicable 100)
- Targeting WSUS Client with the Registry keys: How to configure WSUS Clients to get Updates from the WSUS server using Registry.

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 server was created from a clown (AMI) and new ones will be generated automatically.
