I previously had my two laptops (P4 2.4GHz, 512MB, XP Home and P2 366MHz 256MB, XP Pro) connected via a MS Home Network and with ICS through the P4 laptop. I was always having problems with the ICS being blocked on the P2 computer by the firewall (several tried). The other disadvantage of this setup is that the primary computer must always be on. I have now set up a simple network with the two computers connected to a Linksys BEFSR41 version 2 cable/DSL Router with a 4 port switch. I now have independent access to the internet via the two computers, so no problems here. The information given and setup CDROm were easy to use for this phase. I am totally new to networks I am unsure of what I am doing. I have setup Zone Alarm pro 220.127.116.11 on both computers Zone Alarm Pro on the P4 (used to initially setup the Router) tells me that I have two networks, 192.168.0.0/255.255.255.0 and 192.168.1.0/255.255.255.0. Zone Alarm Pro on the P2 tells me I have only have one network 192.168.1.0/255.255.255.0. My problem is this I would like to share files, drives and the printer (connected to the P4) but so far I have been unsuccessful. The computers are both connected to the MSHome network but no domain is specified. What I need is some sound advice and the recommendation of a good but simple book on networking. Now i know most of you will be very bored over the next few days with very little to do so i am hoping that i will get a good response. merry Christmas to you all.
