Reset WSUS Authorization and get new WSUS SID

Sometimes Machines will get updates from WSUS and not report. This is usually caused by Duplicate WSUS SIDs shared between machines. This is usually a result of cloning or deploying from a template. Once you run this script the machine will delete its current SUS ID and reach out

      Personally I also make the folder on the computer and in a GPO computer

$path = "c:\windows\SoftwareDistribution" 

Stop-Service wuauserv 

Push-Location
Set-Location -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate"
Remove-ItemProperty . -Name SUSclientid
Remove-ItemProperty . -Name SusClientIdValidation
Remove-ItemProperty . -Name PingID
Remove-ItemProperty . -Name AccountDomainSid
Pop-Location

Remove-Item -path $path -force -recurse

Start-Service wuauserv

Invoke-Command {wuauclt.exe /resetauthorization /detectnow}

      the line 
wuauclt.exe /resetauthorization /detectnow

will work on all servers except 2016.

In 2016 you will need the following line:
usoclient.exe startscan

Hopefully that helps.

      Ping key will fail
ACcountDomainSID will fail

Those 2 have failed for me 100% across 2008R2/2012R2/2016

However this has worked for me 100%. 
1. Run Powershell as administrator
2. Run this command/bat.
3. Retry Windwows update. Once Windows Update updates the time of the last check to your current time, refresh WSUS Unassigned Computers. You will see your missing server.

No need to reboot.

      Thanks for script. Can we run this from Group Plicy? it will reset wsus id for every time this can be problematic?

      You could run from GP but i don't recommend it. I would only run this when you have issues on individual machines 
Imaging a machine is generally what causes duplicate SID's. which is generally the problem people have and need this script for.
