We've configured two servers MS Windows 2003 Enterprise w/ SP as AD1 and AD2 (Active Directory). They are set-up as Primary and Backup Domain Controllers (respectively).
I made the AD1 as the Enterprise root Certificate Authority (CA) server successfully. Then went on to attempt to make the backup domain controller as the Enterprise subordinate CA. During the installation procedure, I get this message on the subordinate server:
"Cannot Ping the selected CA. Please make sure the CA is running. The RPC
Server is unavailable. 0x800706ba (WIN32: 1722)"
The RPC and RPC Locator service are running on both servers. I can ping the root CA machine by FQDN name okay.
Certificate Services are running on the root CA machine just fine. Any suggestion? Thanks in advance.
