  • AFAIK only one AD Domain can run from a Domain Controller.
    You can build another DC and add that as a second Domain in the Forest.
    On build it as a DC in a new Forest then create a Forest trust between the two.

    It all depends on why you want to do this?

  • Hi,

    That will not be possible. You cannot have 2 domains on 1 DC. If you need multiple domains you need to have multiple DC's for that. As Harrison propose install new server and promote it to DC. Now depending on your need you have options to create a new forest or to add second dc to an existing one.
