Certificate Enrollment Fails


I am trying to create a certificate for a radius server, following these instructions:https://kb.meraki.com/knowledge_base/radius-obtain-a-digital-certificate-for-a-windows-domain-member-system

When I get to the last step of creation I am seeing the error: RPC server is unavailable.

Image of the error is attached.

Anyone have an idea of why this is happening?

This looks like a permission related issue, take a look at the previously answered question at:

Also ensure the server you are enrolling from is in one of the groups allowed the Read and Request Certificates permissions.

Took a look at the other article;

I ran Dcomcnfg.exe > Component Services > Computers > My Computer > Properties > COM Security. I do not have a group called CERTSRV_DCOM_ACCESS. (screen attached)

I am assuming Distributed COM Users is a group I can add the server too?

Also noticed in the event viewer I am getting a 0x800706ba error.
