Can't use Certificate Authority console on Subordinate CA to install Root CA certificate - Windows Server 2012 R2

Hi

I am using the following article to setup a 2 tier certificate services on Windows Server 2012 R2.

http://blogs.technet.com/b/yungchou/archive/2013/10/21/enterprise-pki-with-windows-server-2012-r2-active-directory-certificate-services-part-1-of-2.aspx

The Subordinate CA installed successfully with warnings: Installation is incomplete. To complete the installation use request file to obtain certificate from Parent CA.

I generated a certificate request file, successfully issued a cert for my Subordinate CA from the Root CA, and copied the .p7b certificate file issued by my Root CA to my Subordinate CA Server.

When is try to access the Certificate Authority on my Subordinate CA Server using mmc or the Certificate Authority admin tool I get the following error:

Cannot manage Active Directory Certificate Services.
The network path was not found. 0x80070035 (WIN32: 53 ERROR_BAD_NETPATH)

If it try to start the CertSvc windows service I get the following error:

Active Directory Certificate Services did not start: Hierarchical setup is incomplete.  Use the request file in C:\abc.req.req to obtain a certificate for this Certificate Server, and use the Certification Authority administration tool to install the new certificate and complete the installation.

Help!
