I purchased my first Mac recently, a 12" iBook. My desktop is currently running on XP Pro and I've got it hooked up via ethernet to a Linksys wireless router. I have no problem getting the iBook (wireless) and my PC (ethernet) to share an internet connection. However, I'm having trouble getting them to see each other on the network. Can someone go through what I need to do to get them able to access each other?
