i have checked from my server and found this error : CDP Location #1 expired. I need help

You need to make sure the CA publish a CRL, this can be done locally on the CA server using the command: certutil -crl If the CA is an enterprise CA, the CRL should have been published automatically. In such case, you need to check why the CRL has not been published automatically. You can always check the history of CRL publishing activities by running the Certification Authority console locally on the CA server using the command: certsrv.msc /e /Hasain

certutil -crl said the rpc server is unavailable certsrv.msc /e said results cannot be obtained from a stopped service. please start active directory certificate services. i started the service but got an error 1604 installation suspended or incomplete

Is this a newly installed CA or has it been running for a while and just expired? Could you give us some more info about it? /Hasain

it has been running for some time and realised it expired
