Windows Update failing Windows Server 2016

Question

Hello,

KB5036609 and KB5036899 are failing on one of my client's Servers. The error code that I'm finding in the Windows Update log is Failed to obtain 9482F4B4-E343-43B6-B170-9A65BC822C77 redir SecondaryServiceAuth URL, error = 0x80245002.

This what we've tried so far:

1.) Ran Windows Update Troubleshooter:

2.) Tried manually downloading and installing the updates. Tried rebooting the server.

3.) Reviewed ticket Rebooted server Checked WU Updates still failed Ran commands Net Stop bits Net Stop wuauserv Net Stop appidsvc Net Stop cryptsvc Ren %systemroot%\SoftwareDistribution SoftwareDistribution.bak Ren %systemroot%\system32\catroot2 catroot2.bak Net Start bits Net Start wuauserv Net Start appidsvc Net Start cryptsvc

3.) Ran disk cleanup. 20GB of free space available on the C drive.

4.) Ran sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth

These were the results:

We have rebooted the server multiple times in between these steps. Do you have any other suggestions? Thanks.

Hello   Patrick Wilson3，

Thank you for posting in Microsoft Community forum.

I understand that you are experiencing issues with Windows Update on your client's Windows Server 2016, and you have already tried several troubleshooting steps. Based on the error code you provided, it seems that there is an issue with the Windows Update Agent. Here are some additional steps you can try:

1. Reset the Windows Update components by running the following commands in an elevated Command Prompt:

net stop wuauserv

net stop cryptSvc

net stop bits

net stop msiserver

ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

ren C:\Windows\System32\catroot2 catroot2.old

net start wuauserv

net start cryptSvc

net start bits

net start msiserver

2. Check if there are any pending updates in the Windows Update queue. If there are, try installing them first before attempting to install the failed updates.
3. Check if there are any third-party antivirus or firewall programs that may be blocking the Windows Update process. If there are, try temporarily disabling them and then attempt to install the updates again.
4. If the issue persists, you can try downloading the updates manually from the Microsoft Update Catalog and then installing them manually.

I hope the information above is helpful.

If you have any question or concern, please feel free to let us know.

Best Regards,

Haijian Shan

I have 6 Windows Server 2016 servers that this does not work on.
Windows update install the monthly rollup. It downloads, then appears to install. After reboot to finish the update, it shows up as failed in Update history
