Why won't two XP based computers network when the
internet firewall is turned on? Both p.c.'s have Win XP
Professional. I can acccess the shared folders on each
p.c. if the internet firewall in network-properties-
advanced-settings is turned off. I have no connection if
the firewall is turned on. I enabled "Telnet" in the
firewall options but this doesn't help. I added the IP
addresses of each p.c. in the firewall settings but this
doesn't help either. What am I missing? Thanks.
By design, XP's Internet Connection Firewall (ICF) blocks file and
printer sharing. That's how it prevents other people on the Internet
from accessing your shared folders.
You can enable or disable ICF independently on each network
connection.
If a network connection connects directly to the Internet (dial-up
modem, cable modem, DSL modem), enable ICF on that connection.
If a network connection connects indirectly to the Internet (through
another computer or a broadband router), don't enable ICF on that
connection.
So, for example, on an Internet Connection Sharing host computer with
a cable modem connection:
1. Enable ICF on the cable modem connection.
2. Disable ICF on the local area network connection.

The new Windows Firewall in XP Service Pack 2 is different. It lets
you create an exception that allows folder sharing between your own
computers while blocking access by other people on the Internet. I
strongly recommend installing Service Pack 2. For more information:
