To verify DNS registration and functionality

  1. Open a Command Prompt.

  2. On a Windows Server 2003 computer, type the following command, and then press ENTER:

    netdiag /test:dns

    Note

    For a more detailed response from this command, add /v to the end of the command.

    On a Windows Server 2008 or Windows Server 2008 R2 computer, type the following command, and then press ENTER:

    dcdiag /test:dns

    Note

    For a more detailed response from this command, add /v to the end of the command.

    If DNS is functioning, the last line of the response for all operating system versions is DNS Test…..: Passed. The verbose option lists specific information about what was tested. This information can help with troubleshooting if the test fails.

    If the test fails, do not attempt any additional steps until you determine and fix the problem that prevents proper DNS functionality.
