Failure to connect to a domain controller is normally due to a network connectivity problem or a permissions problem. To check and correct potential connectivity problems: Check that AD DS is running by confirming that Active Directory services are running on each domain controller. Use network diagnostic tools, such as the Ping and Nltest command-line tools, to check the status of the network connection from the certification authority (CA) to AD DS. Use the procedure Confirm permissions on essential AD DS containers and objects below to confirm that the CA has the correct permissions to objects and containers in AD DS. MSG_NO_CERT_TYPES This error code indicates that the CA looked for a list of certificate templates in the CertificateTemplates container in AD DS, but either could not find the list, or the list was empty. To check and correct potential certificate template problems: Use the procedure Confirm certificate template configuration and availability to check the permissions and other settings on the certificate template and that it has been added to the CA. MSG_DOMAIN_INIT This error code indicates that the CA could not connect to AD DS. This failure may be the result of a network connectivity problem or, more likely, a permissions problem.
