Microsoft PKI: problem with autoenrollment for domain controllers Grovnasch 08-14-2007

Hello everybody,
I have the following problem on my AD-Domain (3 Domain Controllers
with MS-PKI):
all the domain controllers have recurrent errors in the Application
Event Viewer that say:
"Automatic Certificate Enrollment for local system could not find a
valid certificate templete to match DomainControlleras specified in
the group policy automatic enrollment object. Enrollment will not be
performed."
The "DomainController" template is the standard template, which I have
removed from the "Certificta templates to issue" container. Besides, I
have created a new personnalized DomainController template, called
MyDomainController, which is accepted by all the CDs, i.e. all the 3
of them have been issued a valid certificate. Nevertheless, all domain
controllers still ask for a "DomainController" Certificate, although
there is no entry at all in the Default Domain Controller Policy (-->
Computer Settings --> Windows Settings --> Security Settings -->
Public Key Policies --> Automatic Certificate Request Settings).
If I try to reintegrate the "DomainController" template on the CA to
--
> Certificate Authority --> My CA --> Certificate Templates: New Cert
Template to issue, I get the following error: "The template
information on the CA cannot be modified at this time. This is most
likely because the CA service is not running or these are replication
delays. One or more certificate templates to be enables on this
certificate authority could not be found. The changes can be saved to
Active Directory and retrieved by the CA next time it is started. Do
you want to save the changes to Active Directory?".
Clicking "Yes" and restarting the CA does not solve the problem...
Did anyone have the same problem? Any ides?
Thanks in advance,

Microsoft CAs are hard coded to request the Domain Controller certificate.
WIndows SErver 2003 introduced the Domain Controller AUthentication
certificate template, which supercedes the Domain Controller.
My question for you is why you have decided to create your own template,
rather than using the defaults?

Hello,
I duplicated the DomainController template to be able to modify
certain setttings while still keeping the original copy.
Autoenrollment with my personnalized MyDomainController template works
fine, I jhust don't understand why the DC's still try to autoenroll
with the DomainController template. It is not specified in either
policy.-
Besides, the DomainController template says in the Certificate
Tempaltes MMC: Minimum supported CA: Windows 2000; Autoenrollment: not
allowed... bizarre that it is not compatible with autoenrollment...
When I try to add the template with certutil -SetCATemplates
+DomainController, it generates the following error:
DomainController: Adding
CertUtil: -SetCATemplates command FAILED: 0x80094813 (-2146875373)
CertUtil: One or more certificate templates to be enabled on this
certification authority could not
be found.

Certutil -Template does not display the DomainController tempalte,
whereas it is shown in the Certificate Templates MMC....
