In addition, when I had problems with establishing a fully operational 
home LAN, I used "Network Magic". It has a free fully operational trial 
period which I think recently has been made made permanently free. It is 
a very user friendly program. I also have two desktops and a laptop and, 
also, when I visit my daughter who uses Network Magic, my laptop is 
automatically tied into their LAN as a permitted visitor.

Visit www.networkmagic.com and decide if you want to at least give it a 
trial.
