I got some warnings regarding Event ID 64 CertificateServicesClient-AutoEnrollment
SOLUTION :
Open PowerShell and use command
cd CERT:\\ ls Get-ChildItem -Path "xxxxxxxxx" -Recurse
If PowerShell can’t find it use the GUI
Open mmc and add the Certificates snap-in.
And search for the HASH Key in all stores.
Certificate seems to be expired.
Since this certificate relates to Azure AD Connect, which was uninstalled on this server, I can delete it…
Enjoy !
