This procedure verifies that the operations masters can be located and that they are online and responding.

Administrative Credentials

To perform this procedure, you must be a member of the Domain users group in Active Directory.

Note

You can use these tests prior to installing Active Directory as well as afterward. To perform the test prior to installing Active Directory, you must use the /s option to indicate the name of a domain controller to use. You do not need the /s option to perform the test after installing Active Directory. The test automatically runs on the local domain controller where you are performing the test. The commands listed in this procedure show the /s option. If you are performing this test after installing Active Directory, omit the /s option. For a more detailed response from this command, you can use the verbose option by adding /v to the end of the command to see the detailed response.

To verify the availability of the operations masters

  1. Open a Command Prompt.

  2. Type the following command to ensure that the operations masters can be located and then press ENTER:

    dcdiag /s: domaincontroller /test:knowsofroleholders /verbose

    where domaincontroller is the name of a domain controller in the domain in which you want to add the new domain controller. The verbose option provides a detailed list of the operations masters that were tested. Near the bottom of the screen, a message confirms that the test succeeded. If you use the verbose option, look carefully at the bottom part of the displayed output. The test confirmation message appears immediately after the list of operations masters. Press ENTER.

  3. Type the following command to ensure that the operations masters are functioning properly and are available on the network:

    dcdiag /s: domaincontroller /test:fsmocheck

    where domaincontroller is the name of a domain controller in the domain in which you want to add the new domain controller. The verbose option provides a detailed list of the operations masters that were tested. Near the bottom of your screen, a message confirms that the test succeeded. Press ENTER.

    If these tests fail, do not attempt any additional steps until you determine and fix the problem that prevents locating operations masters and verifying that they are functioning properly.
