The WSUS server and 2 other servers will not report to WSUS

Question

All computers and servers are all in the same GPO created for WSUS. All servers are windows 2016, computers windows 10. 3 servers including the WSUS itsels have not reported for over 30 days. I have tried the usual commands of:

wuauclt /detectnow, /reportnow, /resetauthorization none of them do anything.

I have tried all these suggestions - https://www.drivereasy.com/knowledge/windows-update-error-0x8024401c-fixed/#:~:text=the%20error%200x8024401c%20usually%20occurs,device%20drivers%20in%20your%20computer.

again no luck.

I have found this and tried this - https://winaero.com/blog/find-windows-update-log-windows-10/#:~:text=Press%20the%20Win%20%2B%20X%20keys,in%20the%20details%20pane%20below.

again no luck.

I have tried running -

net stop bits
net stop wuauserv
reg delete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v AccountDomainSid /f
reg delete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v PingID /f
reg delete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v SusClientId /f
reg delete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v SusClientIDValidation /f
rd /s /q "C:\WINDOWS\SoftwareDistribution"
net start bits
net start wuauserv
wuauclt /resetauthorization /detectnow
PowerShell.exe (New-Object -ComObject Microsoft.Update.AutoUpdate).DetectNow()

I just keep getting the same error on all of them:

There was some problems installing updates. But W'ell try again later. If you keep seeing this and want to search the web or contact... 0x8024401c

the last working update on all the faulty servers was KB4540723

I have rebooted all of them, I am getting nowhere. They can ping the WSUS server, FW is off on all of them. Please can someone help, im going crazy with it. It makes no sense.

Answer 1

Delete the computer object from the WSUS MMC and run the client side script again

Answer 2

Hi PeteRuggles-7943,

Thanks for your posting on Q&A.

For my further search, please consider providing information:

1. Whether the other clients reported correctly or not.
2. Have you tried to clean up the database recently? If not, please try to clean up the database.

Here is a link for your reference to clean up the superseded updates:
