Hi,
I have a DC that has the Warning Event ID 64 for CertficateServicesClient-AutoEnrollment. I tried to renew the Expired Certificate but I keep getting an Error 16 about "The signature of the certificate cannot be verified." This Certificate expired awhile ago but our AD is working fine, how can I renew this and what exactly is this being used for? Thanks for any help and supporting documents you can provide.
