Enable ICF

I am trying to enable the ICF in XP. I followed the help
file routines and tried the network wizard and can't tell
if its enabled. If I try to enable the ICF manually I
right click on the icon for my ISP and try to open the
properties tab but nothing happens. This is the same for
MSN or AOL. It seems like this option is disabled. This
is my home PC and is the only PC connected to the
internet.

Am I missing something here?

Thanks Chris
