Home Network

I have a new desktop, running XP Home, hardwired to a wireless router, and a laptop, running win98SE, which connects to the router by wireless. Both machines are able to connect to the internet. I am trying to create a home network with these two. The laptop was originally networked with a previous desktop which ran w98. I am having difficulty creating the network, despite running the network setup wizard from the XP machine, and running a network setup disk on the laptop. Does the fact that Norton Security is enabled on the desktop have an effect, as well as Network Neighbourhood for the previous network? Or am I doing something else wrong?
