Running Other Services with ISA Server

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

You can run ISA Server on a computer with other services running already, such as e-mail or Web servers. However, it is not recommended to place other services on the firewall. For improved security and protection, place services behind the firewall, as shown in Figure 5.7. For example, if your organization needs to deploy ISA Server to connect branch offices to the Internet in integrated mode, ISA Server can be installed on existing e-mail or Web servers to simplify deployment and minimize the cost.
