This is a new first time install.
I have a stand-alone Windows 2008 Enterprise R2 SP1 server in a workgroup.
I also have a subCA issuing Certificate Services server in my domain. It is a Windows 2008 Enterprise R2 SP1 server in our domain.
My issuing subCA generates a request for the root CA. I copy this .REQ file  to my stand-alone ROOT CA server. It signs and issues the new cert.
I then open the cert and do a copy/export. It defaults to file with an extension of .P7B.
I copy this .P7B file to my issuing SubCA in my domain.

It is my understanding I need to run CSUTIL DSPUBLISH on this file now so it is in our Active Directory.
IS THIS CORRECT??
Or when I to my copy/export on my stand-alone root CA, do I need to save the file as a .CER file extension, then copy to my issuing subCA server. Where I run CSUTIL DSPUBLISH?

The problem I am having is when I start the services on my issuing subCA it won't start an wants to import my Root CA. When I point it at my copied .P7B file it errors out with the following error:

"The certificate for the CA "mycert-ca" on  myserver.mydomain.com is mssing. Do you want to install the certificate?"

I say yes, then point it at the copied file. Which is a .P7B extension.

Then I get the error;

Cannot find the certificate to build a certificate chain. A certificate chain could not be built to a trusted root authority.

Looks Like I need to run the CSUTIL DSPUBLISH command, but on which file extension?

I just want to be certain before I publish this to my AD.

Am I on the right track? If so which file ext. should I use that I copied from my stand-alone root CA?

Step 1. I created my stand-alone RootCA server and Published my Root CA.

Step 2. I created my issuing CS server in my domain.

Step 3. I generated a request from my issuing CS server in my domain, this created a .REQ file. I copied the file to my stand-alone RootCA and submitted a new request and then Issue the requested certificate.

Step 4. I opened the certificate, copy and exported as a .P7B file.

Step 5. I then copied this file to my issuing CS on my domain. I then tried to start my CA services it prompted me about do you want to load a certificate? When I said yes it would error out with trusted root errors, and chain errors.

Step 6. So I copied the Trusted RootCA that was created during my stand-alone RootCA server setup to my issuing server on my domain. I then ran the csutil -dspubish command as you stated.

Step 7. I then added the Trusted Root Cert. to my Certificate Group Policy of trusted Root Certs.

Step 8. Then from my issuing CS I opened the trusted root cert that I copied from the stand-alone RootCA and opened the cert and clicked on Trust this certificate.

Step 9. I then tried to start the CA services on my issuing CA server, it prompted me do I want to install a certificate. I selected yes, then selected the certificate and my services FINALLY started.
