I am going down the path of designing a PKI.

Initially it will be used to provide SSL for OWA and Citrix but will be
used for secure logon to AD in the future.

The architecture I have come up with after some reading is to install a
Stand-Alone Root CA, publish the CRL and Root Certificate to AD, then
install an Enterprise Subordinate Issuing CA to provide the secure AD
function for the internal users. The Stand-Alone Root would then be
secured off the network.

I would then have another Stand-Alone CA in the DMZ to provide the
certificates for SSL and any future VPN requirements from external
parties.

Does this sound reasonable to the CA knowledgeables out there? Also I
had intended for the DMZ CA to be another Stand-Alone Root but have
read articles stating that this could also be a subordinate Stand-Alone
CA.

TIA,
R.

Your design looks solid. Make sure to consider your root CRL publication
interval, AIA and CRL locations before you get going.
