Appendix A - Using the Antigen utility

Applies to: Microsoft Antigen

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

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.
