XP Service Pack 2
Windows Firewall
Group Policy Setup for Callisto Pop-up
1.0 Overview
By default, Windows XP Service Pack 2 (SP2) enables Windows Firewall, previously
known as Internet Connection Firewall (ICF).
The firewall’s behaviour is such that by default, file and print sharing is disabled, and
most TCP and UDP ports are blocked. In regards to Callisto, this means the Callisto Pop-
up application is unable to communicate with the Callisto Service, as the firewall blocks
any incoming messages.
The firewall can be modified to allow communication on specified ports. For System
Administrators this can be a major pain to have to set each individual machine's firewall
settings.
The Firewall’s setting can be managed using Group Policy, making the task of the system
administrator much easier.

domain administrator).
