Inform all your users of the downtime you'll need. If your server runs
other Internet services, such as Microsoft's IIS, notify your users that the
services will be unavailable while you install IAS.
Make sure the only applications running on the server are those that are
absolutely necessary. The Setup program overwrites particular files on the
server, so if other programs are using them, Setup will not continue properly.
Stop any Microsoft Internet services that you have running, or you can let the
IAS Setup program stop them for you.
Before starting installation, be sure to log in as Administrator or as a
user who is a member of the Administrator group. You will need administrative
privileges to complete the installation correctly.
Gather all the IP address ranges your network uses. You'll need them during
Determine what client operating systems the workstations on your network
run so you can install the appropriate client packages during setup.
Be sure that the disk drive on which you install the software has about
3.5MB of free space available.
Be sure you already have a second network card installed in the server and
that the card is pre-configured with a non-routable IP address, such as
10.0.0.1. If you're connecting to the Internet with a regular modem or
Integrated Services Digital Network (ISDN) connected to a COM port, you'll need
only one network card, because NT sees modems as Ethernet devices.
