The first thing you have to do is install the SMTP service on the machine that will act as the ISA Server. Make sure that the server you are using has two NICs installed. One NIC will connect the server to the internal network; the other one will be exposed to the outside world.
- Open the Control Panel and select the Add/Remove Programs option.
- When the Add/Remove Programs applet opens, click the Add/Remove Windows Components button to launch the Windows Components Wizard.
- Select the Application Server option and click Details.
- Pick the Internet Information Server (IIS) option and click Details again.
- Mark off the checkbox next to the SMTP Service and click OK twice, followed by Next.
Windows will now install the SMTP Service. You may be prompted for your Windows installation CD during this process.
