Hello community,

I have an issue, my windows server 2016 are unable to connect to WSUS but other os (windows 10, windows server 2019 are updated using this update service).

User's image

Here are tests :

  • $(New-Object -ComObject "Microsoft.Update.ServiceManager").Services | Select-Object Name, IsDefaultAUService > WSUS is true and windows update is false
  • WSUS is reachable on web interface using selfupdate/ or browse to ClientWebService/client.asmx
  • Regedit is up to date with GPO
  • On event viewer, i got this error : Windows Update failed to check for updates with error 0x80072EE6.
  • I tested all tips on this site :
  • Create a GPO only for this windows version : same issue

Please can you help me to solve this issue?

    Does the computer show up on WSUS at all as a computer? If so, have you tried deleting it and running the client side script?

    Does it appear again and report in after a while?
