Install a Digital Certificate on Each Domain Controller? (Configuring Active Directory with MX)

[rodesvera]

Hi everyone. I am trying to perform the Configuring Active Directory with MX Security Appliances
But I am somewhat confused in the Install a Digital Certificate on Each Domain Controller step.
Can someone explain to me step by step how to perform this configuration in a Windows Server 2019 domain controller.
I would appreciate your help as I have tried to search for more documentation in this regard and have not located any. Thank you.

What about this one?

Hi, friend. that's exactly the point that I don't understand what to do. The explanation is very ambiguous. They do not explain if you have to install the CA role on your server and create a certificate. I would like more details about it
