|Microsoft Internet Security and Acceleration Server 2000|
Set up an internal SMTP server to work with ISA Server.
Microsoft SMTP server comes with Internet Information Services (IIS) 5.0, which is part of the default installation of Windows 2000 Server.
Use the MSEClnt installation share on the ISA server.
Add a text file called wspcfg.ini, with the following content, to the winnt\system32\inetsrv directory, and then restart IIS:
[inetinfo] ServerBindTcpPorts=25 KillOldSession=1 Persistent=1
net stop "World Wide Web Publishing Service" net stop "FTP publishing service net stop "Simple Mail Transport Protocol (SMTP)" net stop "IIS Admin Service" net start "Microsoft SMTP Service"
Note When you switch from a Firewall client test configuration to a SecureNAT client test configuration, or from a SecureNAT client to a Firewall client, the Firewall service and the SMTP service must be stopped and restarted.
