Hi Steve,
It appears that I did not correctly set up my CRL and AIA publication
settings from the get go.
I deployed my enterprise offline root and subordinate CA with these defaults.
I am using AD and GP with autoenrollment for deploying ONLY the certificate
chain to the client computers .
I currently have a limited internal cert deployment, only for PEAP for
wireless.

I hope there is an easy fix...
I see where to change the CRL, AIA settings .....After I update them
Do I have to re-issue all the published certificates? And/or will the
changes (if allowed) propagate down the chain?

I also read, that it is recommended to configure empty CDP and AIA ext to
ensure that the certificate chaning engine does not perform revo checking on
the rootCA. Do you agree?

Before I set my CRL and AIA.....
I need to plan ahead for the day my subordinate server is replaced with
another, and want to have a consistent dns cname for the CRL and AIA files (
I don't want to use a server name) . I prefer to use the LDAP or a DNS
pointer to the current subordinate CA http.
