I hear that you have to uninstall and turn off the
firewalls on the computers when you try to set-up a
network. Is this correct? If so, how do you protect your
computers afterwards? Do you just simply install it again
later?
 
Greetings Sarah,

The XP's firewall is only intended for direct connections to the Internet
not local area networks. If you wish to use protect your computers, I
suggest a third party firewall. XP's firewall only blockings incoming
connections, it doesn't protect outgoing and a third party firewall does
everything XP's firewall does and more.

Sarah,
As mentioned in a previous reply, if you are talking about th
Microsoft built-in version, it is essentially for a small home networ
and does not offer the protection even a freeware firewall like Zon
Alarm would offer.
If you have a firewall up, keep it in place while adding the machine t
the network. There are no valid reasons to drop your guard to add
machine. In the worst case scenario, you will be prompted to allo
access for that machine on your network. Some older firewalls or les
friendly (TinY) firewalls may not even prompt you but will document th
attempt to connect to the network from the newly added machine. Fro
there, you simply configure it to allow the IP address or range i
within a set IP pool

Uh, to quibble with your words a bit: I'd say that XP's ICF is *not*
intended for small home networks; it is only good for end-nodes which
are not on LANs, since ICF inhibits file and printer sharing on LANs.

And, as pointed out, ICF only blocks incoming traffic, while Zone Alarm
and many other firewalls also block outgoing traffic.
