As an NT service

If the gateway machine is an NT machine and you installed WorkgroupMail as an NT service, you can start the WorkgroupMail server by double clicking on the Services applet in Control Panel, locating the WorkgroupMail service and pressing the Start button.

Note: Ensure that you have specified the correct username and password when logging onto your ISP. A bug in Windows causes dial up networking to hang when run from an NT service if an incorrect username and password is supplied.
