Hi!
I'm in the process of setting up an W2K3 server / Windows XP client IPSEC /
L2TP VPN service. Everything so far works fine in the lab, except the target
service will have multiple DCs for the single domain for resilience. I would
like to configure the system to have more than one certificate server to
allocate machine certificates, however I'm at a loss as to how to do this.
Configuring one DC as an enterprise CA works wonderfully, but configuring a
second one as a subordinate CA then powering the enterprise CA and DC off
doesn't seem to result in allocation of certificates that can be used to
establish a VPN connection.

Is having a resilient certificate server, possible and / or practical or am
I making a fundamental mistake here?

Thanks

Kevin
