The following table contains a summary of the DNS records that are required to support the hardware load balanced Director. The role of the Director requires similar DNS records as the Front End Server. The number of records needed is reflected in the subject alternative names required on the Director certificate. Different from the Front End Server, the Director pool does not host user accounts or host the Mobility Services.
