Appendix A - Using the Antigen utility

 

Applies to: Microsoft Antigen

Topic Last Modified: 2009-07-23

The Antigen utility (antutil.exe) is a command-line tool with which you can enable or disable Antigen.

noteNote:
Unlike a reset, the Antigen services are not removed. Only the dependencies that have been set are removed.

The antutil.exe command is located in the Microsoft Antigen for Exchange installation directory. It has the following parameters:

  • antutil /enable - Enables Antigen by reestablishing dependencies.
  • antutil /disable - Disables Antigen by removing dependencies.
  • antutil /status - Displays an onscreen report showing the status of Antigen and the server.

There are other parameters, but they should be used only when you are directed to do so by support technicians.

You can use the Antigen utility to disable and enable Antigen.

To disable Antigen
  1. Stop the Microsoft Exchange and Antigen services.

    noteNote:
    In a clustered environment, when running the Antigen utility to disable Antigen, the Exchange services are automatically taken offline. Therefore, you can skip step 1 and proceed directly to step 2.
  2. From a command prompt, navigate to the Antigen for Exchange installation directory. Disable Antigen dependencies by typing:

    antutil /disable

  3. To confirm that the Antigen dependencies have been removed, type:

    antutil /status

  4. Restart the Exchange services.

CautionCaution:
When you are not running Antigen, you do not have its protection.
To enable Antigen
  1. Stop the Exchange services.

    noteNote:
    In a clustered environment, when running the Antigen utility to enable Antigen, the Exchange services are automatically taken offline. Therefore, you can skip step 1 and proceed directly to step 2.
  2. From a command prompt, navigate to the Antigen for Exchange installation directory. Enable Antigen dependencies by typing:

    antutil /enable

  3. To confirm that the Antigen dependencies have been reestablished, type:

    antutil /status

  4. Restart the Exchange services.
