You may have heard a lot of horror stories about trying to network a new Vista machine with your old XP machines, and you may have even tried it on occasion with no joy. I know I had.
However, this time around, I was determined to get it working properly. I, once again, Googled for articles explaining how to network the two machines. This time, however, I was able to find a somewhat recent article on the subject (in the past, the majority of the articles I came up with were written when Vista was still in its beta stages). I followed the steps in the article and was 95% of the way to having my two computers networked together successfully.
The last two pieces of the puzzle for me, however, were: 1) setting the correct permissions on my Vista files and folders and 2) configuring my Norton 360 firewall to allow the networking to happen.
