Networking

After setting up a network between my desktop and laptop it worked fine
until I started making changes based on security suggestions I found on
trusted sites on the web. Now I have problems connecting the computers
and when I am able I have problems with it trying constantly to access
my dial up connection which is continuous until I unplug the network. I
now want to remove all old settings and and start from scratch.

It is a simple direct cable network with no router. I don't need to
connect to the web via the network as they each have access to the phone
line. First, how do I clear all settings so that they do not show back
up in a new setup. Second, all I want to do is share files and the
printer between these computers and let them access the net individually.

Which of these packets should I install “Internet Protocol (TCP/IP)”,
“File and printer sharing for a Microsoft network”, “QoS Packet
scheduler”, “Client for Microsoft networks”.

Also aren't these settings individual to each connection you set up? The
notebook also is wireless 802.11 bg , which I use when I work out of
town each week, at several eating establishments which are not secure.
Should I only install the TCP/IP protocol to prevent access to it in one
of these networks. I have heard about setting up a VPN on this
connection but all info I find is more confusing than helpful.

Both machines are running Win XP Home SP2. Laptop is HP Pavillion zv6130 AMD Athlon 64-3200, 512 MB ram, Desktop custom AMD Athlon XP2500+, 1 Gig ram . Both use builtin Realtech network interface.

I know this is a lot to cover and have looked on the news feeds for
info, but have been frustrated trying to interpret what I find as a lot
of it is not stated in a way that is understandable to a ignorant
novice. Any help is appreciated, Lee
