Windows 2016 Servers does not show up on WSUS console

Happens most times because the servers are created from an AMI (never syspreped)

Note: All other servers are reporting to WSUS such as Windows server 2008R2 and Server 2012 R2 but Windows Server 2016 does not.

Note: All registry keys are created on Server 2016 and there is connectivity between the wsus server and the windows server.

Solution: Delete the SusClientID and SusClientIDvalidation keys from the registry. This is because the sever was created from a clown (AMI) and new ones will be generated automatically.

Steps

  • Stop windows update service
  • Delete SoftwareDistribution folder 
C:\Windows\SoftwareDistribution folder

Run the commands below from the commandLine

wuauclt /resetauthorization /detectnow

And this as well

wuauclt /detectnow /reportnow
