I modified your supplied error message and asked google.

The first link looks interesting. Have you seen Google.com?

I have Microsoft Fax Server Version 5.2.1776.0 which was included in XP Home Edition SP 2.
I cannot view any incoming faxes.
This is the message I receive: The fax document cannot be displayed because your operating system does not have a default viewer for fax documents (.tif files).
What should I do to get this "default viewer"?
