I have WSUS installed on a Windows 2016 server. It has been up and running for at least a year and was working fine on a small domain consisting of Windows 2016 (the WSUS server)/2008R2 servers and Windows 10/7 workstations. About a month ago we upgraded the domain, removing the 2008R2 servers and replacing them with another Windows 2016 server running Exchange and 3 Windows 2019 servers, 2 of which are DCs. We use group policies to manage the updates and have the same group policies applied to the Windows 2016 and 2019 servers.
In checking the servers for updates (the first time since the upgrade), I'm finding that no Windows 2016 updates have been downloaded in WSUS. However, the 2016 servers are checking in and reporting status to WSUS. They also show other approved updates ready to install, including Office updates and the SQL updates.But they do NOT show that they're being managed when looking on the server itself, i.e., no message stating "Some settings are managed by your organization," even though one of them is the WSUS server.
Never seen this one before...strange!
