Windows server 2022 / 21H2 failing windows updates

Question

2 - Instances of Windows server 2022 / 21H2 failing windows updates. Showing Error encountered - last checked 9/12/23. Have gone through the normal channels. Have run the troubleshooters. I have run SFC and variants. I have manually installed kb5031364 for Server 2022 21H2. I have run DISM tools. We have other Windows 2022 / 21H2 servers having no issues at all. Need a fix.

Answer 1

Hello Jay Scott (jscott)

Based on the troubleshooting steps you have already taken; I would recommend trying the following:

1.In services.msc, are Windows update service and Background Intelligent Transfer Service open?

2.Whether the network is connected?

3 Check if there are any third-party antivirus or firewall software installed on the affected servers and temporarily disable them to see if it resolves the issue.

4. Check if there are any pending hardware driver updates and install them manually in the Device Manager.

Answer 2

I have experimented with them both running and not. Has no impact...

AV agents disabled. Firewall open. No impact.

There are no firmware updates to be performed.

Answer 3

Is the September cumulative update (KB5030216) installed?

Answer 4

No it is not. I will try installing that now.

Answer 5

This server is definitely 21h2 - however this update KB5030216 is coming up N/A for this machine.
