I have not much experience in networking . I had bought a 2 m LAN cable and connected my PC with win XP and my MacBook Pro . but now I don't know how to start. I read the guide http://guides.macrumors.com/Networking_Windows_with_Mac_OS_X but in the beginning it says .. But I never see the workgroup or Computers . All the networking window show is two Icons "Library" which shows some not found error and "Servers" which has a link to my Mac. Also, how do I know my Mac and PC's IP address ?
