Hello; Recently I noticed that my CA is expired and I cannot access my Certificate Authority console; I get an error message Access Denied (the service Certificate Services is stopped). If I try to manually turn on the service it goes for few seconds then its shut off again. In logs I have the following erros : A certificate in the chain for CA certificate 0 for IT has expired. 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). Certificate Services did not start: Could not load or verify the current CA certificate. IT 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 Certificate Services service terminated with service-specific error 2148204801 (0x800B0101). I've run C:\>certutil -error 2148204801 0x800b0101 (-2146762495) -- 2148204801 (-2146762495) Error message text: A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file . CertUtil: -error command completed successfully. What should I do in order to renew the CA ?
