Before you set up ISA Server 2006, review ISA Server SE Installation Requirements.

When you install ISA Server, you will be requested to supply the following information.

• CD key. This is the 25-digit number located on the back of the ISA Server CD-ROM case.
  
  
• Installation options. You can select one of the following:
  
  
  • Full installation. All components are installed
    
    
  • Custom installation. You can select which components to install.
    
    
• Internal network configuration. You must configure the address ranges to include in the Internal network. For more information about the Internal network, see the product documentation.
  
  

  Important:
  Because the Internal network must include an IP address that is defined on a network adapter that is currently connected and enabled, you can continue past the Internal Network setup page only if the internal network adapter is connected, enabled, and has the correct IP address assigned.

• As part of the installation process, ISA Server modifies the TCP/IP driver's dynamic port range, setting it to 65,535.
