How to install and configure a firewall on a computer in Windows 2000

This article was previously published under Q312624
SUMMARY
This article describes how to install Internet Security and Acceleration (ISA) Server and configure it as a firewall. To install the ISA Server schema to Active Directory, you must be an administrator on the local computer. In addition, you must be a member of both the Enterprise Admins and Schema Admins groups. You have to install the ISA Server schema only once to Active Directory for the entire enterprise or organization.

CAUTION The enterprise initialization process copies the ISA Server schema information to Active Directory. Because Active Directory does not support deletion of schema objects, you cannot reverse the enterprise initialization process.
