“Certificate Services did not start: Could not load or verify the current CA certificate. mail A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file. 0x800b0101 (-2146762495).”
I checked the system time and that was good so I went into the Computer Certificate store and found 2 certs that had expired and as I mentioned one of them was the CA Root Cert. So I opened the Certificate Authority on the Cert Server and it had failures to open some of the pieces of this because of the service was not running. But it allowed me to right click on the server name and select Renew CA Certificate. Once I did that the services started and life was good again.
Till later just Roger]]>
