WSUS - Client server issues

Question

Hello Good day,

I have a odd situation with two client servers.

All updates approved on WSUS, current month (July2021) but only KB890830 is showing as needed on those two servers, all the other clients servers reporting to this WSUS have no issues.

Deleted the server from WSUS and ran below script:
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 "%SystemRoot%\SoftwareDistribution"
net start bits
net start wuauserv
wuauclt /resetauthorization /detectnow
PowerShell.exe (New-Object -ComObject Microsoft.Update.AutoUpdate).DetectNow()

Servers are reporting well but same issue onlt KB890830 is showing.

Any suggestions on how to tshoot/resolve this?

Thanks

Answer 1

Some more testings.

I removed both servers from WSUS and configured them to go get updates in internet and they have needed updates for this month.

Once i force them back to WSUS, back to same issue, only KB890830 is showing.

Answer 2

I ran Solarwinds diagnostic tool and it is showing some error on "content" and "iuident.cab"

"content" - Error forbidden - incorrect proxy client config - i don't have any proxy
"iuident.cab" - Invalid URI, a port was expected because of there is a colon - Invalid WUServer URL

i can open https://server-FQDN:8531/clientwebservice/client.asmx with no issues, i can download iuident.cab

Any other suggestions?

Thanks
