I have often seen that the revocation list distribution points of a Server 2008 R2 certificate authority were configured incorrectly or not at all. Therefore, I describe here how to restore the distribution points of an Active Directory integrated certificate authority under Windows Server 2008 R2.
The distribution points are configured under the "Extensions" tab in the properties of the certification authority.

Here are the standard distribution points and the properties:
C:\Windows\system32\CertSrv\CertEnroll\.crl

ldap:///CN=,CN=,CN=CDP,CN=Public Key Services,CN=Services,

http:///CertEnroll/.crl

file://<ServerDNSName>/CertEnroll/<CaName><CRLNameSuffix><DeltaCRLAllowed>.crl

And here are the default values for accessing job information:
C:\Windows\system32\CertSrv\CertEnroll\_.crt

ldap:///CN=,CN=AIA,CN=Public Key Services,CN=Services,

http:///CertEnroll/_.crt

file://<ServerDNSName>/CertEnroll/<ServerDNSName>_<CaName><CertificateName>.crt

After the changes, the blacklists can be published at the new locations:
