A Certificate is one of the obvious things when it comes to identity verification of a user, machine, server, service, application, and many things in the digital world. The ideal process to get a?digital certificate?is: CSR (Create a?Certificate Signing Request), Submit the CSR to a CA (Certificate Authority), and Download the certificate after the CA issues your CSR. We have covered the first part, which is?creating a CSR, in another article. In this article, we are going to cover how to request a certificate from Windows ADCS.

After successful submission of the certificate request, note down the “Request ID”. Ask the CA administrator to issue the certificate.
