There are several tasks that should be performed before you install PMDF for the first time. These tasks are discussed below.

1. Disable any existing SMTP server, so that the PMDF SMTP server can replace it. To disable this SMTP server:
   1. Go to Start Menu --> Settings --> Control Panel --> Administrative Tools --> Services --> Simple Mail Transport Protocol (SMTP). Click "STOP", and set "Startup Type" to "Disabled".
      OR
   2. Go to Start Menu --> Programs --> Administrative Tools --> Services --> Simple Mail Transport Protocol (SMTP). Click "STOP" and set "Startup Type" to "Disabled".
2. Configure the Windows Task Scheduler (also called the Scheduler) so that it runs automatically. To configure the Scheduler:
   1. Go to Start Menu --> Settings --> Control Panel --> Administrative Tools --> Services --> Task Scheduler (or it might just be called Scheduler, depending upon your version of Windows). Click the "Startup" button and set it to "Automatic".
