Specifying an instance name

Updated: August 22, 2005

Applies To: Windows Server 2003 R2

On the Instance Name page, you must provide an easily recognizable name for the Active Directory Application Mode (ADAM) instance that you are installing. This name is used on the local computer to uniquely identify this ADAM instance.

The name that you specify appears in the following places:

  • Event Viewer

  • Services snap-in

  • Add or Remove Programs

To specify an instance name

  • On the Instance Name page, type a name for the ADAM instance that you are installing, and then click Next.


  • The Active Directory Application Mode Setup Wizard presents a default instance name of instanceX, where X equals 1 for the first ADAM instance that is installed on the computer, 2 for the second ADAM instance that is installed on the computer, and so on.

  • The name that you specify must meet the following requirements:

    • It must be unique with respect to other ADAM instances running on the same computer.

    • It must be no longer than 44 characters.

    • It must use characters only from the ranges of a through z, A through Z, or 0 through 9.

    • The name "ntds" cannot be used.

  • The instance name that you specify is used to construct the service name, the service display name, and the service description, as follows:


    Name supplied during setup Service name Service display name Service description




    Blank (No default description is provided.)

  • You can modify the service display name, as well as the service description, after installation. For more information, see Related Topics.
