Hi there,
We have been asked by a client to renew their Exchange server certificate, however when we tried to renew the cert we received the following error:
Event ID 22 Certification Authority
Active Directory Certificate Services could not process request 56 due to an error: 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). The request was for CN=clientdomain.com, OU=client ou, O=client o, L=Edinburgh, S=Midlothian, C=GB. Additional information: Error Verifying Request Signature or Signing Certificate
We noticed that the Root certificate had expired so we renewed it via the CA. However the error persists and we are unable to issue certificates.
Can anyone help?
Steve
