WSUS detects that the server exists but that is about it.Įvery other OS works fine, it is only the 2016 servers that have this problem. I created a completely new 2016 server installation with absolutely nothing installed on it no roles, no firewalls no virus scanner no nothing, just a blank server and tried to force it to connect. There is no firewall or port blocker or anything like that. The client can be pinged from the WSUS server. I have verified in the registry on the affected machines that they are pointing to the WSUS server and it can be pinged. I have verified that the machines are in the correct groups in AD and in WSUS. I have run the cleanup wizard to deny and remove all of the superseded updates. I have run the wuauclt /reportnow and wuauclt /detectnow. I have ensured that BITS and the Windows Update services are running. I have a hard time believing that there are 0 applicable updates for a fresh Windows Server 2016 install. Since they have been installed they have gotten 0 updates. I have manually gone through the installed updates on one of the servers in question and verified that these 'Not Applicable' updates are not installed.Īll these servers are fresh installs and they are in an OU that prevents them from restarting themselves after an update install and I am the only one who manually restarts them. The status for all of them is 'Not Applicable' They are all Critical updates and Security Updates. If I run a report on one of the servers and I set the product filter to 'Windows Server 2016' I get 31 updates installed or not applicable.Īll 31 updates are set to approval 'Install'. These are fresh server installs, they have just been installed straight from a disk image created November of last year. It shows 0 updates needed, all updates show 'installed or not applicable'. WSUS will detect but not send updates to any of the 2016 servers. WSUS detects and sends updates to all systems, including the 2012 servers. We have a WSUS server running on Windows Server 2016.
