For Fax Sharing to work on Windows XP (SP2), you’ll need to do the following:

Reconfiguring Windows XP security settings

To enable Fax Sharing, perform the following steps at the host computer, and then repeat sections 1-4 at the client computer. Do all of the sections in the order given.

Section 1: To ensure that the Windows Firewall is enabled

At the host computer, log on as a user with Administrative privileges. If you already performed sections 1-7 at the host computer, logon at the client computer instead.
From the Start menu, click Settings > Control Panel.
If using the Classic View, double-click Windows Firewall. Otherwise, click Security Center and then, in the “Manage security settings for:” section, click Windows Firewall.
Select On (recommended).

Section 2: To add the WinFax Controller program to the Windows Firewall Exceptions list.

On the Exceptions tab, click Add Program.
Select Controller. The “Path:” box displays a path that ends in Wfxctl32.exe.
If the host and client are on the same network (subnet), click Change scope and select My network (subnet) only.
Click OK, and then click OK again.
In the Programs and Services list, ensure that the box next to Controller is selected.
Click OK, and close the Windows Control Panel.

Section 3: To enable Remote Administration traffic through the Firewall by enabling RPC and DCOM
