Windows 2022 21H2 Cumulative Updates Failing
I have a Windows 2022 21H2 server that is a domain controller this has happened the last 2 months where the Windows CU do not install. They fail with error 0x800f0831. The CU for .NET installs fine, but the Windows CUs fail every time with the same error. this happened on KB5031364 and on KB5030216. It is a newly build VM that I built a back in August of 2023. I've tried the Windows Update Troubleshooter, Disk Clean up, with and without our Anti-Virus software. BITS is Automatic (Delayed start) and Running, Windows Update is set to Automatic and running. I've tried deleting the C:\Windows\SoftwareDistribution folder. I've also tried applying the CUs from Windows update and downloading them directly from the Windows Catalog download site. Everytime I get the same result, failed 0x800f0831Windows Server 2016 does not install updates at scheduled time
We have an OU for servers that we don't mind if they install Windows Updates and reboot nightly. For some reason, the Server 2016 servers in that OU do not automatically install updates at the time scheduled by the GPO. The settings on the servers appear to be applied correctly, and it does detect that there are updates available... it just doesn't install them at the scheduled time. Settings from relevant Windows Update GPO: WU settings on the server: WU Restart Options on the Server: WU Policy Registry settings on the server: Any suggestions as to why this may be?
