WSUS update server not updating clients (Server 2019)?

Question

Hi ,
we have WSUS and different servers in our network.
Windows 2019 does not automatically connect to the WSUS server.
WSUS Server (Windows Server 2022),
This was reinstalled to rule out errors here (previously Windows Server 2016)!
Windows update log from windows server 2019
Date of last check 07.02.2022 > there was a manual search

Regards
Wolfgang

Answer 1

Hi Rita,
no, it affects 3 Windows 2019 servers with remote service.
1 of them has updated today.
All other servers Windows 2016 have no problem.

Reset Windows Update

Some DLL's could not be found e.g. muweb.dll.
netsh winsock reset needs a reboot, this is only possible tonight.

Answer 2

Run the client side script after deleting it from the WSUS MMC Console and see if that fixes it

If it doesn't, continue down the page for troubleshooting.

Hello Wolfgang,

Thanks for your posting on Q&A.

This was reinstalled to rule out errors here (previously Windows Server 2016)!

Would you mind talking more about this? I want to get more information before moving on.

Please try to share the below registry values on the Windows Server 2019.

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate

Best regards,
Rita

Hello @Wolfgang Barthel

Can you confirm that WSUS URL is: https://WSUS.local.de

Have you always used port 8531?

What is the startup type of wuauserv ?

Can you share all WU configuration from: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate

Thanks,

Hi ,
Thank you for your answer!
I exchanged WSUS in the log for the correct name and the domain name (anonymous).
The same settings work on the other servers (e.g. Windows 2016).

@ ajtek-adam-j-marshall
i will run the scripts and delete from WSUS
