If the hostname of a primary domain controller or an additional domain controller (ADC) has more than 15 characters, you must ensure that the first 15 characters of a new ADC that is added to the domain is different from the first 15 characters of the primary domain controller or any existing ADC in the domain. Not complying with this guideline will lead to failure in provisioning of the new ADC.
