Certs for Domain Controllers-Trying to Prevent an Issue Christian 03-19-2008

Reposting this issue. It was recommended that I post to this group from
someone in the AD group.

We have three DC's, all running Windows Server 2003 w/SP2. DC1 is unstable,
and needs to be demoted before there is a serious hardware failure. DC2 and
DC3 have been brought online, and all of the FSMO roles have been moved to
them. The one remaining issue is that DC1 issued the Domain Controller
certs to DC2 and DC3. No other certs in our environment where created by
DC1, just the Domain Controller certs for DC2 and DC3. What needs to be
done in order to allow the demotion of DC1 out of AD without affecting the
certs? This server will be salvaged after the demotion.

Thank you,

-Christian

Easiest would be to deploy a proper PKI (not piggy-backing a CA on a DC)
You can use certutil -dcinfo deleteALL to replace the certs after the new
PKI is deployed
You cannot restore the CA. If you read the installation warning, you cannot
change the domain or NetBIOS name of the CA after installing Cert Services

Hi Brian,

Just out of interest. I'm reading your w2k3 PKi book right now and like it
very much. Will there be a w2k8 version?

It is in progress right now. Brian's writing it and I'm tech editing it.
